It have organized Channels for different types like for examples announcements, general etc, for working Professional plus you can divide specific conversations for specific projects, topicss etc.

It has Built in AI and Automation which I like the most about it and it is very optimized as per my usage. Review collected by and hosted on G2.com.

There is one thing I hate about Slack bacause we have partners, colleagues around the globe.

Similar to other tools like Notion etc, there should be an option to add a special type while writing/typing for datetimes so when I say we meet at 4 pm, it should automatically translates to what that mean for the people in different time zones. Review collected by and hosted on G2.com.

What I like most about Slack is how it keeps team communication organized without overwhelming everyone. Channels make it easy to separate discussions by project or team, while threads prevent conversations from becoming cluttered. The search functionality is excellent, allowing me to quickly find old messages, shared files, or links instead of asking teammates to resend information.

Slack also integrates seamlessly with tools like Jira, GitHub, Google Drive, and CI/CD notifications, which helps keep important updates in one place and reduces context switching. The desktop and mobile apps are fast and reliable, and the clean UI makes it easy to navigate even with multiple workspaces. Features like huddles, reminders, message scheduling, and workflow automation have improved collaboration and saved time. Overall, Slack has streamlined communication, increased team productivity, and reduced the need for lengthy email chains. Review collected by and hosted on G2.com.

While Slack is an excellent communication platform, the notification system can sometimes become overwhelming, especially in large workspaces with many active channels. It takes some time to fine-tune notification settings to avoid distractions without missing important updates. The search feature is powerful, but locating older conversations can occasionally be difficult if you don't remember specific keywords.

Another drawback is that message history and certain advanced features are limited on the free plan, which can be restrictive for smaller teams. Slack also uses a fair amount of system resources when multiple workspaces are open. Although integrations are one of its biggest strengths, managing a large number of app notifications can sometimes make channels feel noisy. Overall, these are relatively minor issues compared to the value Slack provides for day-to-day collaboration. Review collected by and hosted on G2.com.

What's kept me on Slack for years isn't any single feature, it's that it quietly becomes the searchable memory of a team. Threads keep side conversations from burying the main channel, and search is good enough that the answer to "why did we do it this way" from six months ago is usually one query away.

The second thing is how much of my actual workflow lives inside it without writing glue code: CI/CD results, monitoring alerts, and PR pings land in the right channel through webhooks and the App Directory, and Workflow Builder handles routine approvals and reminders without any engineering effort. For anyone doing on-call work, a dedicated incident channel with pinned status updates is one of the simplest, most effective ChatOps patterns out there, it doubles as a ready-made timeline when you sit down to write the postmortem.

What's made me more bullish on where it's headed: Slack recently rolled out a native MCP server, letting outside AI tools query workspace data through a standardized, permission-aware protocol instead of a pile of one-off integrations, plus real-time secret-scanning that flags an API key someone pastes into a channel before it turns into an incident. Small details, but they show the platform evolving with how engineering teams actually work now, not just chasing chat features. Review collected by and hosted on G2.com.

The free plan quietly undercuts the exact thing I praised. History and file visibility roll off after 90 days, and anything older than a year is deleted unless you've upgraded, so "searchable team memory" only holds up if you're paying for it or you've built your own export habit. The same free tier caps you at 10 third-party app installs, which bites fast once you're piping in CI/CD, monitoring, and a ticketing tool at the same time.

Second is scope creep. What used to be a very good chat app now also wants to be a workflow engine, a docs tool, a lightweight CRM via Salesforce channels, and a full AI agent that drafts messages and summarizes channels for you, and a lot of what makes it smart is limited to Business+, Enterprise+, or a separate AI add-on. None of these are bad individually, but tracking which capability lives on which plan has become its own chore. Slack

That AI point cuts both ways: Slackbot can already send messages, update your status, and take actions on channels on your behalf once you've approved it. Useful, but I'd want clearer after-the-fact visibility into what it did and why, not just a one-time permission prompt. And on Linux, the desktop client is still a heavy Electron app, noticeably more RAM-hungry than a messaging tool should be Review collected by and hosted on G2.com.

It’s easy to keep track of important conversations and organize day-to-day communication with company members.

I can’t imagine a workday without Slack.

There’s no shortage of connections, and the voice and video quality in Huddles is magnifique.

Although the price isn’t cheap, for a small-to-medium company it’s affordable for the value you get.

It offers a wide variety of integrations, and you can even create your own. It’s also very easy to use, with different ways to connect with the Slack backend.

I can’t really comment on support because I’ve never needed it. Everything works as it should, and it’s always been clear how to use it. Review collected by and hosted on G2.com.

If I have to say something… it’s owned by Salesforce. In my experience, when Salesforce takes over anything, it tends to become a pain in the ass and ends up super expensive. Review collected by and hosted on G2.com.

Using Slack day to day feels like juggling really good collaboration with some equally specific annoyances. On the good side, a lot of our team culture has grown around custom emojis, little graphics we've made that basically stand in for running jokes only we understand. When our Huddle calls turn into messy brainstorms, Slack Canvas is what I reach for to pull that mess into something that actually looks like a dashboard afterward. Search modifiers are another one I rely on constantly, things like during:march, has:link, or from:@user help me find decisions from years back in seconds instead of scrolling forever. And with sidebar nesting, I've been able to fold a bunch of unrelated channels into folders so my sidebar doesn't feel like chaos. Review collected by and hosted on G2.com.

Honestly the Huddle join sound gets me every time, that sharp ringing noise the second someone starts a call just breaks whatever focus I had going. There's also this quiet pressure around the green status dot, like people are watching whether you're active, so you end up clicking around just to look present. Threads are another pain point, they branch off into replies on replies until it's genuinely hard to figure out where a decision actually got made. Review collected by and hosted on G2.com.

Slack's performance over the past decade has consistently set a high bar. Its easy-to-access UI works without extensive tutorials, which is genuinely valuable, and it offers multiple day-to-day features that are intuitive and practical. Fast integrations with Okta, Jira, and Claude are very helpful and have become essential for routine workflows. The upcoming AI capabilities — such as summarising context and meetings, rephrasing content, and more — look particularly promising and useful. Ongoing support for understanding user intent, paired with features like screen sharing, audio and video calls, and maintaining thread continuity, further enhances collaboration and creates a positive impact. Together, these elements make Slack a reliable, productive tool for everyday team communication. Review collected by and hosted on G2.com.

During a video call, when screen sharing opens in full-window mode, I can’t quickly access the slack conversation from the desktop icon — trying to open it doesn’t bring up the chat. I have to minimise the shared screen and then open slack to view the chats. Review collected by and hosted on G2.com.

What i love about Slack is how organized it keeps all the communication.And for multiple teams we can create different channels to seperate the chats for specific projects.It is also very user-friendly along with the features like file sharing,integration that saves a lot of time. Review collected by and hosted on G2.com.

Although it makes the chats organized but when you are a part of multiple channels then your chats will get buried under constant notifications.So i need to manually scroll to the chat or need to search.Also the free version has limited features like message history is restricted.

Slack makes team communication much easier and keeps everything organized in one place. I like how conversations can be separated into channels, so it's easy to find the right information without searching through long email threads. The integration with other tools, quick file sharing, and reliable notifications help me stay on top of my work. It's simple to use, works well on both desktop and mobile, and has made collaborating with my team much faster and more efficient. Review collected by and hosted on G2.com.

One thing I don't like about Slack is that it can become overwhelming when you're part of many channels, as it's easy to miss important messages. The search feature is useful, but finding older conversations isn't always as straightforward as I'd like. Also, the free version has message history limitations, which can be frustrating when trying to look up past discussions. Other than that, it's been a reliable tool for day-to-day communication.

What I like most about Slack is how it keeps communication organized without slowing people down. Channels make it easy to separate conversations by team or project, searchable history helps you quickly find context, and integrations with tools like Google Drive, Jira, and GitHub reduce context switching. It supports both real-time collaboration and asynchronous work, making it easier for teams to stay aligned regardless of where or when they work. Review collected by and hosted on G2.com.

One aspect I dislike is that Slack can become overwhelming when there are many active channels and notifications, making it easy to miss important updates. However, I think this is manageable with good channel organization, notification settings, and clear team communication practices. Overall, the benefits of fast collaboration and transparency outweigh this drawback.

Also i could not able to pin channels in a particular order Review collected by and hosted on G2.com.

It feels less like a formal work tool and more like a personalized communication space for the team. The UI is clean, friendly, and easy to use, but what really stands out to me is the way Slack lets people communicate beyond just plain text. Emojis, reactions, GIFs, quick replies, threads, and huddles make conversations feel more natural and expressive, especially compared to more formal workplace tools.

I also like how customizable and flexible each chat or group can be. You can pin important documents, keep useful links in a channel, react to messages, organize conversations in threads, and make a workspace feel specific to how your team actually works. Even the profile experience feels a little more human and less corporate, which makes day-to-day communication feel lighter.

Another big plus is the number of integrations. Slack connects well with tools we already use, like Gmail, Lattice, and other workplace apps, so updates and workflows can come into one place instead of being scattered across multiple platforms. Overall, Slack makes collaboration feel faster, more connected, and more personal without losing the structure needed for work. Review collected by and hosted on G2.com.

Honestly, there is not much I actively dislike about Slack. The only thing that sometimes bugs me is that Slack has so many features that I feel I am probably not using it to its full potential. For example, I would like to use Slack more as a personal document organizer or link organizer, but I do not always know the best way to set that up or build that habit.

It would be helpful if Slack prompted users more proactively with learning paths, tips, or use-case-based onboarding. For example, if someone frequently saves links or pins documents, Slack could suggest better ways to organize them, create workflows, or use features that already exist. So my issue is less about the product lacking features and more about discoverability. There is a lot of value in Slack, but I would appreciate more guidance on how to unlock it.
