Effortless Communication with Stellar Flexibility **Rating:** 5.0/5.0 stars **Reviewed by:** giorgi d. | coordinator, Consumer Services, Enterprise (> 1000 emp.) **Reviewed Date:** November 14, 2024 **What do you like best about Mattermost?** I use Mattermost at work for inside company communication, and I think it's really easy to use. I like how it can send and receive every type of information, like text, photos, files, and zip files, which is super handy. It's fast to use and I can choose between the desktop version, web, or mobile app, and they are all comfortable to use. I have also connected it with my job's mailbox, allowing me to save every chat with my boss in my mailbox. The initial setup was easy, and everything is simple to find in the app. I think Mattermost is one of the best, and I can't remember any issues. **What do you dislike about Mattermost?** i have use it more then 6 years and can't remember anything i wanted and app hasn't it **What problems is Mattermost solving and how is that benefiting you?** I find Mattermost easy to use for sending and receiving all types of information. It's fast and convenient across desktop, web, and mobile. I like having my chats synced with my mailbox, especially conversations with my boss. ### 2. Great secure alternative to Slack for tech-heavy teams **Rating:** 4.0/5.0 stars **Reviewed by:** Maximilian C. | Team Lead Recruitment, Small-Business (50 or fewer emp.) **Reviewed Date:** March 16, 2026 **What do you like best about Mattermost?** The biggest advantage of Mattermost is the ability to self-host it. Since data privacy is a huge concern for us, having full control over our chat data on our own servers is a gamechanger. The interface feels very familiar if you've used Slack before, so onboarding the team was incredibly easy. I also really appreciate the deep integrations with developer tools like Jira and GitLab. **What do you dislike about Mattermost?** The mobile app can sometimes be a bit clunky. Push notifications are occasionally delayed by a few seconds compared to the desktop app, which can be slightly annoying when you are away from the keyboard. Also, the search function could be a bit smarter when looking for older files. **What problems is Mattermost solving and how is that benefiting you?** We needed a central communication hub that doesn't store our sensitive company data on third-party cloud servers. Mattermost solves this perfectly. It keeps our internal communication organized in channels without compromising our strict compliance and data security rules. ### 3. Flexible Self-Hosted Control, But UI and Plugin Ecosystem Feel Behind **Rating:** 3.0/5.0 stars **Reviewed by:** Victor S. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** April 30, 2026 **What do you like best about Mattermost?** What I appreciate most about Mattermost is the level of control and flexibility it gives me. Because I run it self-hosted, I can keep everything within my own infrastructure, so performance, privacy, and compliance stay in my hands instead of being tied to a third-party SaaS environment. For engineering teams, that kind of autonomy is a genuine advantage. I also value the developer-friendly workflow. Channels and threads remain easy to follow even when conversations get busy, and integrations tend to behave predictably. With webhooks, slash commands, and custom bots, it’s straightforward to tailor Mattermost to internal workflows rather than forcing the team to fit a rigid tool. **What do you dislike about Mattermost?** The biggest downside for me is that parts of the platform still feel a bit dated compared with newer collaboration tools. The UI is functional and reliable, but it isn’t as polished or modern as some alternatives, which can make the overall experience feel a little utilitarian. Self-hosting is definitely a strength, but it also comes with extra overhead. Upgrades, backups, and plugin management require ongoing maintenance, and even small configuration issues can take time to troubleshoot. If you don’t have a solid DevOps setup in place, that operational burden can add up quickly. The plugin ecosystem also feels more limited than Slack or Teams. While the core integrations work well, there are times when I wish there were more out-of-the-box options, rather than having to build custom bots or scripts to fill the gaps. **What problems is Mattermost solving and how is that benefiting you?** Mattermost gives me a secure, self‑hosted hub for engineering communication. It centralizes alerts, discussions, and automation in one place, cutting down on context switching and keeping sensitive data inside my own infrastructure. It’s fast, reliable, and easy to integrate into DevOps workflows. ### 4. Fast, Secure Team Messaging with Full Control and DevOps-Friendly Integrations **Rating:** 4.0/5.0 stars **Reviewed by:** Abir S. | SEO Consultant, Small-Business (50 or fewer emp.) **Reviewed Date:** February 02, 2026 **What do you like best about Mattermost?** What I like best about Mattermost is the control it gives you without sacrificing collaboration. It delivers fast, reliable team messaging while letting organizations self-host, customize, and meet strict security or compliance needs. Channels keep conversations focused, integrations plug neatly into DevOps workflows, and everything feels purpose-built for teams that value transparency, ownership, and serious work over noisy chat. **What do you dislike about Mattermost?** What I dislike about Mattermost is that it can feel less polished out of the box compared to some mainstream chat tools. Initial setup and administration require technical effort, and advanced features often need configuration or plugins to shine. **What problems is Mattermost solving and how is that benefiting you?** Mattermost solves the problem of insecure, uncontrolled team communication by giving organizations full ownership of their collaboration environment. It replaces fragmented chats, shadow IT tools, and compliance risks with a secure, centralized messaging platform that integrates deeply with workflows. The benefit is trust and focus—teams communicate in real time, keep sensitive data in-house, and collaborate efficiently without compromising security or operational control. ### 5. Secure, Customizable Self-Hosted Messaging That Boosts Team Collaboration **Rating:** 4.5/5.0 stars **Reviewed by:** Vo P. | học sinh, Small-Business (50 or fewer emp.) **Reviewed Date:** March 31, 2026 **What do you like best about Mattermost?** What I like most about Mattermost is its strong focus on security and customization. The option to self-host gives us complete control over our data, which is a major advantage compared to other messaging platforms. On top of that, the interface is clean, performance has been reliable, and the available integrations make team communication and collaboration noticeably more efficient. **What do you dislike about Mattermost?** One thing I don’t really like about Mattermost is that it can feel a bit less polished compared to other tools, and sometimes the setup or integrations take more effort than expected. **What problems is Mattermost solving and how is that benefiting you?** Mattermost helps keep all team communication in one place and makes it easier to organize discussions. It also gives us better control over our data, which is important for security, and overall it makes collaboration faster and more efficient. ### 6. Reliable, Secure, and Perfect for Organized Team Communication **Rating:** 5.0/5.0 stars **Reviewed by:** Himanshu V. | Product Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** December 01, 2025 **What do you like best about Mattermost?** Mattermost is reliable, fast, and keeps all internal communication organized in one place. I like how it’s built with privacy and data control in mind, which makes it stand out from typical cloud-based messengers. Channels, threads, and integrations with tools like Jira and GitHub make it great for team coordination. It feels professional but still easy to use for quick updates or in-depth project discussions. **What do you dislike about Mattermost?** The interface can feel a bit dated compared to newer messaging apps, and the mobile version sometimes lags or misses notifications. Setting up integrations also takes some trial and error, especially for non-technical users. A few small improvements in search speed and UI polish would make the overall experience smoother. **What problems is Mattermost solving and how is that benefiting you?** Mattermost helps streamline team communication across projects and departments, especially when working remotely. It replaces scattered email threads and unstructured chats with a central, searchable platform. The result is faster decision-making, fewer miscommunications, and better visibility into what everyone’s working on. It’s made collaboration much more structured without adding unnecessary complexity. ### 7. Streamlined Team Communication with a Few Notification Hiccups **Rating:** 4.0/5.0 stars **Reviewed by:** Tammy H. | IT Specialist/Business Owner, Small-Business (50 or fewer emp.) **Reviewed Date:** April 28, 2026 **What do you like best about Mattermost?** I like Mattermost for work since it provides a clean interface, making it easy to navigate. The ability to use chat is good and the platform is quick and responsive. The interface is pretty easy to use, with standard menus that simplify finding what I need. Setting it up was fairly simple and straightforward. **What do you dislike about Mattermost?** The notifications did not always come through as configured, so things were lost sometimes. Also, when Mattermost was upgraded, there was no communication about the change, so it was frustrating to figure out the new updates without any heads up. **What problems is Mattermost solving and how is that benefiting you?** I use Mattermost for communicating between different areas and specialties at work, as well as with our global team. ### 8. Reliable for Communication, Needs UI Update **Rating:** 4.0/5.0 stars **Reviewed by:** Suresh P. | CloudFinOps Lead, Mid-Market (51-1000 emp.) **Reviewed Date:** May 04, 2026 **What do you like best about Mattermost?** I've been using Mattermost for a while now, and it's been reliable for team communication, especially with external partners. It works well for DevOps workflows. I also appreciate the cost savings at scale since there are no costs per usage, which means no SaaS headaches. **What do you dislike about Mattermost?** I feel the UI is a bit outdated. A more modern and intuitive UI would add an advantage. Also, it was a little difficult because technical effort is required to set up. **What problems is Mattermost solving and how is that benefiting you?** I have used Mattermost for reliable team communication, especially with external partners, and it works well for DevOps workflows. It offers cost savings at scale, avoiding per usage SaaS headaches. ### 9. Mattermost could be a next Whatsapp for the Corporate! **Rating:** 4.5/5.0 stars **Reviewed by:** Abhishek S. | Senior UI/UX Designer, Mid-Market (51-1000 emp.) **Reviewed Date:** November 21, 2025 **What do you like best about Mattermost?** I feel using Mattermost in the office is exactly like using WhatsApp, it’s so easy to use. I use the Mac version of Mattermost, so whenever someone messages me, the app icon bounces and gives me a hint with a notification sound, which is very useful. And yes, it’s also a bit addictive. We colleagues sometimes set GIF profile pictures just to add some fun while chatting this is the feature I like the most. I never require customer support. Whole day we use Mattermost only **What do you dislike about Mattermost?** Sometimes, finding a group or a person in the long list becomes difficult. I remember seeing some onboarding screens that explain Mattermost shortcuts, but I haven’t been able to find them again. After the latest update, the option to use a GIF as a profile picture also seems to be hidden, it’s quite hard to locate now. Files above 15 MB can’t be shared on Mattermost, and there’s also an issue with SVGs. I have to zip the file first, otherwise Mattermost doesn’t show it as a downloadable asset. Mattermost should find more ways to find new fun features that help office people feel more engaged. **What problems is Mattermost solving and how is that benefiting you?** Earlier, we used WhatsApp in the office for internal communication. For that, we had to rely on WhatsApp Web on our desktops, which often felt awkward because our personal messages were also visible there — it really affected privacy. Now, for both formal and informal communication, we use Mattermost. I can easily connect with anyone across the entire organization, and it genuinely feels like every person is just one “Hi” away. We can also pin groups or people at the top of the list, which is especially helpful when working on projects with a specific team. ### 10. Efficient, Self-Hosted Solution for Secure Team Collaboration **Rating:** 4.0/5.0 stars **Reviewed by:** Aaditya Raj K. | Game Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** January 14, 2026 **What do you like best about Mattermost?** I appreciate Mattermost for its easy-to-use interface and the ability to create different channels for different teams within the company. Hosting our own server makes everything fast, and it is valuable to integrate a lot of useful systems and custom bots in the platform. Having our important data stored on the company server and the option for developers to set up and integrate various bots and tools easily are significant advantages. I find the bot commands especially useful for creating instant tickets and receiving automatic notifications for different alerts. The fact that custom bots can provide helpful information from external systems inside Mattermost is a great feature as well. Additionally, the overall setup process was pretty easy, aided by online video tutorials and documentation. **What do you dislike about Mattermost?** I don't like that the search system is sometimes too cluttered and shows everything, making it hard to find what I'm looking for. Also, the UI design seems primitive compared to competitors like Slack. **What problems is Mattermost solving and how is that benefiting you?** Mattermost allows us to self-host our server, keeping important data in-house. It's fast, easy to use, and supports custom bot integration, making internal communications and notifications efficient. ### 11. Reliable Platform with Room for UI Improvement **Rating:** 4.5/5.0 stars **Reviewed by:** Abhishek C. **Reviewed Date:** December 28, 2025 **What do you like best about Mattermost?** I use Mattermost as a secure team collaboration and messaging platform to support day-to-day communication and coordination. I appreciate how it helps keep conversations organized through channels, direct messages, and integrations, especially in environments where data privacy and self-hosting are important. The platform eliminates the need to rely on multiple tools or public chat apps by combining messaging, file sharing, and integrations in one place. I like how it centers on reliability, transparency, and control, which builds trust within the team. It supports disciplined communication through clear channels and integrations, which helps teams stay aligned without noise. Mattermost grows alongside technical and organizational needs, making it feel like a platform you invest in, not just a tool you use. Its strong focus on security, permissions, and self-hosting addresses compliance and data ownership concerns while keeping conversations organized and easy to follow across teams and projects. **What do you dislike about Mattermost?** While Mattermost is strong in reliability and security, the interface feels very utilitarian, which can make everyday use feel less intuitive or engaging compared to more modern collaboration tools. Some useful features are buried in menus or settings, making them harder to discover without prior experience. Onboarding can also be challenging for new or non-technical users, as concepts like permissions, integrations, and self-hosted configurations often require extra explanation. Additionally, managing plugins and updates can feel manual and time-consuming, especially in larger deployments. Improving the visual polish, simplifying configuration flows, and providing clearer in-app guidance would make Mattermost easier to adopt while preserving its core strengths. **What problems is Mattermost solving and how is that benefiting you?** I use Mattermost for secure team collaboration, solving fragmented communication issues by centralizing discussions and integrating workflows in one platform, emphasizing data privacy and self-hosting. ### 12. Perfect for Collaboration and Self-Hosting **Rating:** 4.0/5.0 stars **Reviewed by:** Alessandro L. | Managing Partner, Small-Business (50 or fewer emp.) **Reviewed Date:** May 05, 2026 **What do you like best about Mattermost?** I like the possibility of running it in self-hosted mode, which allows us to reduce costs while having complete control over our data. Additionally, the mobile app is very intuitive, aesthetically pleasing, and extremely functional. **What do you dislike about Mattermost?** The server deployment cannot be performed on machines with ARM architecture. **What problems is Mattermost solving and how is that benefiting you?** It allows me to communicate effectively on projects and create a company knowledge base. The self-hosted mode reduces costs and manages data, and the mobile app is functional and aesthetically pleasing. ### 13. Easy Direct Messaging, Quick Group Chats, and Fast File Sharing **Rating:** 4.5/5.0 stars **Reviewed by:** Niranjana Devi D. | Project Manager, Computer Software, Mid-Market (51-1000 emp.) **Reviewed Date:** February 18, 2026 **What do you like best about Mattermost?** Direct messaging is easy, and creating a group chat with users is quick and straightforward. File sharing is also fast, which makes it convenient to send documents without delays. **What do you dislike about Mattermost?** One thing I’ve always had issues with is their updates. Sometimes the updated installer fails for no clear reason, and then after a while it works fine again. **What problems is Mattermost solving and how is that benefiting you?** We use this for our organization’s internal communication and calls. It helps us stay connected and collaborate smoothly in a hybrid setup. ### 14. Self-Hosted Mattermost: Full Data Sovereignty with Excellent Webhook Integrations **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** January 31, 2026 **What do you like best about Mattermost?** The primary reason we chose Mattermost is the ability to self-host. working in a secure environment, we cannot have our operational chat logs stored on a public cloud servers; Mattermost gives us full data sovereignty. Beyond security, the webhook integrations are excellent. We have easily scripted our monitoring tools (like Zabbix and Grafana) to pipe alerts directly into specific "War Room" channels, which keeps our incident response strictly internal and organized. **What do you dislike about Mattermost?** ​The mobile app experience can be frustrating, specifically regarding push notifications on the self-hosted version. Getting reliable alerts requires either using their encrypted relay server or compiling your own app, which is a significant administrative hurdle for our team. Additionally, the search functionality isn't as intuitive or "fuzzy" as Slack's; if you don't recall the exact keyword or file name, retrieving older documentation from chat history can be difficult. Managing the server upgrades also adds to our operational overhead, as it requires manual maintenance windows rather than being a seamless SaaS update. **What problems is Mattermost solving and how is that benefiting you?** ​We are primarily using Mattermost to solve the issue of data sovereignty and secure communication. Because we handle sensitive infrastructure data, we are restricted from using public cloud-hosted messaging platforms for our Ops channels. Mattermost allows us to keep all our chat logs and file shares on-premise and behind our firewall, ensuring we meet strict compliance standards. Operationally, it serves as our "ChatOps" hub we have replaced cluttered email threads with webhook integrations that pipe critical network alarms directly into incident channels, which has significantly reduced our reaction time during outages. ### 15. Instant and innovative tool for social chatting **Rating:** 4.5/5.0 stars **Reviewed by:** Gaurang Y. | Associate consultant, Mid-Market (51-1000 emp.) **Reviewed Date:** August 29, 2025 **What do you like best about Mattermost?** An straight foreword tool for fast and protected messaging facility and sharing work too. The application also has the ability to manage and track multiple business channels under this one shade. Centralizes the work of collaboration within teams and external members also from other organization. Document sharing enhances in the app, as it allows to send files from your end to others seamlessly with your team members or even with the external teams also. All the operation involved in the app are completely protected and secured end to end. Mattermost tries its best to meet all enterprise requirements, manage and message instantly. Also it does support to have business calls, conferences, video meets instantly when needed that to with single person or in groups, everything is supported here. Software even allows to integrate with various platform and web pages, to import documents/data and sometimes for connecting with the online business world wide. The enhances the ability of connecting to more people and increase leads. **What do you dislike about Mattermost?** While switching to multiple devices with same account credentials, the server needs to be updated everytime. **What problems is Mattermost solving and how is that benefiting you?** This product was really a blessing for our team as we were able to us connected all the time with our customers and team also. We were able to manage our business workflow, track projects status and even it allowed to easily connect and collaborate seamlessly. ### 16.

MatterMost Review **Rating:** 5.0/5.0 stars **Reviewed by:** Elie S. | Information Technology Consultant, Small-Business (50 or fewer emp.) **Reviewed Date:** October 08, 2025 **What do you like best about Mattermost?** Easy to work with and easy to implement and host it in the Azure cloud services. **What do you dislike about Mattermost?** I found it difficult to customize the mobile app and personalize it with my own name. It wasn't a straightforward process, so I ended up needing to hire Android developers to assist with the customization. **What problems is Mattermost solving and how is that benefiting you?** I use this to stay connected with my customers, organize classroom trainings, and facilitate discussions among colleagues. ### 21. one stop convenient work tool **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** September 08, 2025 **What do you like best about Mattermost?** Looking at Mattermost from my perspective as a data product officer, what stands out most is how it streamlines cross-functional collaboration in our data workflows. The combination of channels, direct messaging, and task assignment features works really well when I'm coordinating between data scientists working on models, engineers handling pipeline deployments, and business stakeholders who need updates. Instead of juggling Slack, email, and separate project management tools, I can keep conversations contextual and assign specific roles or tasks right within the chat threads. The threading feature is particularly useful during model reviews or when troubleshooting data quality issues - I can keep technical discussions organized while still giving business heads visibility into progress without overwhelming them with implementation details. The search functionality across all channels helps when I need to reference previous decisions or find specific code snippets that were shared weeks ago. And since it's self-hosted, our security team is happy with how we handle sensitive data discussions. The integration capabilities with our existing data stack (Jupyter, Git, monitoring tools) mean less context switching for the team. Overall, it's made our data product development cycles more transparent and collaborative across all the different roles involved. **What do you dislike about Mattermost?** The constant code formatting is my biggest pain point. I'm sharing SQL queries, Python scripts, and config files all day with data scientists and engineers. Having to wrap everything in triple backticks kills momentum during rapid debugging sessions - paste code, realize it's unreadable, edit to add formatting, repeat. It's death by a thousand cuts. Search fails me when it matters most. In stakeholder meetings, when someone asks about a model decision from months ago, I know we discussed it but can't find it. The search is too basic - no proper filtering, no context awareness. I end up scrolling through endless channel history while everyone waits, which looks unprofessional. Mobile is unreliable for critical moments. Data pipelines break at inconvenient times, and coordinating emergency responses from my phone is painful. Notifications are inconsistent, the interface is clunky, and I've missed production issues because alerts didn't come through properly. That's unacceptable when you're managing data products that business depends on. **What problems is Mattermost solving and how is that benefiting you?** Mattermost solves the coordination nightmare of managing data products across technical and business teams. Before, I was juggling Slack for quick chats, email chains for stakeholder updates, and separate project tools for task tracking. Critical context got lost between platforms, especially when coordinating model deployments that involve data scientists, engineers, and business stakeholders who all need different levels of detail. The biggest business problem it fixes is visibility gaps during data product development. When a model needs urgent fixes or a pipeline breaks, I can loop in the right people immediately without losing technical context. Business heads can see progress without getting overwhelmed by implementation details, while technical teams can dive deep in threaded discussions. This eliminates the constant "can you update me on..." interruptions that used to fragment my day. It's also solving our compliance headache. With sensitive customer data discussions happening across multiple tools, our security team was constantly worried about data governance. Having everything centralized and self-hosted means we control our data science conversations end-to-end, which removes a major blocker for working with regulated datasets and sharing model insights with stakeholders. ### 22.
