It’s very customisable and helps organisations work better together. I really like being able to set up different types of channels and groups, depending on what the team needs. The new canvas feature has also improved the quality of my 1:1s, because it makes the information you need easy to find and access in one place.

It’s also useful for communicating across organisations. On top of that, there are loads of integrations with other apps like Google Suite, Kadence, Miro, and more, which means you rarely need to leave Slack to stay on top of your work day. Review collected by and hosted on G2.com.

Although I’m a big fan overall, it can still be hard to track down previous conversations. The search functionality isn’t great, and the AI features haven’t reached a point where they feel truly indispensable. I’d also add that, despite improvements over the years, managing the sheer volume of chats and channels I’m part of remains difficult. Review collected by and hosted on G2.com.

What I like best about Slack is how easy it makes day-to-day communication within the team. We use different channels for projects, QA discussions, release updates, and automation notifications, which keeps conversations organized instead of mixing everything in emails. Sharing screenshots, documents, and quick updates is very smooth, and the search feature also helps find recent discussions quickly.

One feature that has been especially useful for us is Incoming Webhooks. We integrated our Selenium automation framework with Slack, so after every automation execution, the test summary is posted directly into a dedicated Slack channel. Previously, we used to send automation reports through Email, but Slack made the process much faster and easier for the team to track in real time. Review collected by and hosted on G2.com.

One limitation I noticed in Slack is the restricted chat history in the free version. Sometimes we need to refer to discussions or shared files from older projects, but older conversations are not always available. Apart from that, the overall experience has been very smooth for daily collaboration and communication. Review collected by and hosted on G2.com.

I like Slack because it keeps team communication organized and easy to follow. The channel system helps separate topics, so conversations don’t get mixed up. It reduces the need for long email threads.

The search feature makes it easy to find past messages, files, or links without wasting time.

Finally, the integration support. I can integrate with tools like Google Drive, Zoom, and project management platforms. So, I don't have to switch between multiple apps during work. Review collected by and hosted on G2.com.

Slack can sometimes feel overwhelming when I need to stay active across many channels and group conversations at the same time. A large number of notifications quickly flood the dashboard, which can become distracting during busy workdays. In fast-moving teams, important messages may also get buried under ongoing discussions, making them easy to miss.

In those situations, the search feature becomes very important. While it is generally helpful for finding older messages, shared files, or specific conversations, the experience is not always as smooth as I would like, especially in large workspaces with a long message history.

In our organization, Slack serves as our official communication medium, keeping everyone aligned. Beyond text-based chat, we frequently use the Huddle feature for quick, seamless voice and video collaboration. Additionally, the ability to build and implement workflow automation is fantastic—it really helps our teams optimize daily tasks and work much more efficiently.

Sometimes the constant stream of messages and notifications can become overwhelming, making it difficult to focus on deep work. It requires strict personal setting management to avoid notification fatigue and maintain a good work-life balance. Review collected by and hosted on G2.com.

What I like best about Slack is that it goes far beyond being just a messaging platform. The integration with Salesforce and other tools makes collaboration much more efficient by centralizing communication, notifications, workflows, and updates in one place.

I especially like how you can interact with business processes directly from Slack, automate tasks, and stay connected with your team without constantly switching between platforms. Features like channels, huddles, integrations, and Slack AI help keep communication organized and productive instead of overwhelming.

The user experience is intuitive, performance is reliable in day-to-day usage, and the onboarding experience is smooth even for new users. From a business perspective, Slack can significantly improve team collaboration, productivity, and response time, which brings real value to organizations using it as a central workspace.

Sometimes the amount of notifications and conversations happening at the same time can feel overwhelming, especially in highly active communities or large organizations.

It can take some time to fully organize channels and customize the experience in the best way for your workflow. Review collected by and hosted on G2.com.

I really appreciate how straightforward the app is and how clean the UI looks, and it has performed consistently well for me. The theme customization options are genuinely useful, and the chat summarization feature saves me time by cutting down on how much I need to scroll back and reread earlier messages. Huddles are another great feature, and they’ve been a helpful addition to the overall experience. Integrations are solid as well, including Jira, Calendar, and others. Review collected by and hosted on G2.com.

It automatically switches to quiet mode and pauses notifications for all messages, which really shouldn’t be enabled by default. Also, Huddles should allow remote control of the machine that’s sharing its screen. Review collected by and hosted on G2.com.

I love how easy it is to organize chat channels by specific projects and teams. It completely stops me from wasting hours searching through endless emails, and the real-time huddles feature makes it incredibly fast to jump on a quick voice call to solve problems instantly with colleagues.

The notification system can become incredibly overwhelming and noisy when you belong to multiple active channels, as the non-stop pings make it very difficult to stay focused. Additionally, the built-in search functionality often feels clumsy and inaccurate when you are trying to find specific files or older buried conversations from months ago. Review collected by and hosted on G2.com.

What I like best about Slack is how incredibly intuitive and user-friendly it is right from the start.The interface feels natural and clean, so even new team members pick it up in minutes without needing training. On top of that, the integration compatibility is outstanding. It connects seamlessly with almost every tool we use, pulling notifications and updates right into channels. The admin features are also extensive yet surprisingly intuitive: setting up user groups, permissions, channel management, security policies, and compliance settings is straightforward and powerful without being overwhelming. Overall, Slack has become the central hub for our team's communication and workflow at work, saving time and reducing email clutter dramatically. Review collected by and hosted on G2.com.

Some features that I’d consider relatively basic are locked behind higher-tier pricing plans. For example, the ability to export the contents of a channel to a PDF or another format isn’t available, unless you’re willing to take an inordinate number of screenshots and stitch them together. Permissions management for users and channels is not well organized and explained. Administration is doable, but can be a bnit of a headache at times. Review collected by and hosted on G2.com.

I like that it is the corporate version of Discord, in a UI/UX sense, and includes all the features someone in an office would use, just like someone gaming or chatting would in Discord. Such features include marking people as VIP, muting certain threads, and the ability to add code snippets, which is particularly useful.

It has good integration with GitHub, but its behaviour is a bit inconsistent, because one of my colleagues wasn't able to get the embed to show, and he was sure he hadn't disabled it when prompted initially, and we couldn't figure out how to enable GitHub embeds for him like they were on for me. JFYI, he had his GitHub connected to Slack.

I can imagine Slack lacking some performance on low-end devices, but that's an issue with all the browser-based applications (Electron), so I can't totally blame them. Review collected by and hosted on G2.com.

If there were a solution for the lags and delays during screen share with a lot of people on call, it would be good. Another thing is also the huddle control bar that appears when in a huddle, and the sharing screen becomes a blank bar on Mac OS sometimes (rarely, but observed by my senior colleague and me too).

Also, there should be an easier way to just silence or completely remove some Apps/Integrations on a personal user level, as they can get pretty annoying, and muting doesn't work. e.g., Birthday Bot with the "I'd like to remind you about some important events" message now and then.

Slack makes teamwork feel simple. I really like how easy it is to jump into a channel, share updates, and follow conversations without losing track. Being able to send quick messages, react with emojis, and keep files organized in one place makes collaboration feel smooth and natural. Overall, it helps keep everyone connected and on the same page. Review collected by and hosted on G2.com.

One downside of Slack is that conversations can end up scattered across multiple channels, which makes it easy to miss important updates. When several threads are active at the same time, it can feel overwhelming to keep track of what’s happening where. Notifications also build up quickly, and that can interrupt my focus.
