Comments and Reviews

   
Comment summary: Slack is praised for its ease of use, intuitive design, and seamless integration with various other apps, making it a popular choice for team communication and collaboration. Many users appreciate its capabilities for organizing discussions through channels and integrating tools like Google Drive and Asana. However, criticisms include concerns about its high memory usage, issues with features becoming paid services, and requests for improved security and notifications. Some users find its user interface unfriendly and compare it unfavorably to open-source alternatives.

As an application that I use across multiple devices and multiple professional and personal contexts, Slack manages to deliver an effective, efficient, and truly seamless collaborative hub. Not only do we use it here at AlternativeTo, but many companies and both formal and informal working groups use Slack every day to maximize collaborative productivity while minimizing the effort needed to ensure that everyone is on the same page. With the ability to create workspaces that can house seemingly limitless channels, as well as support for plenty of add-ons that can both enhance productivity as well as give you a moment to breathe (such as polling or GIPHY icon GIPHY gifs, respectively), Slack can ensure that you're never far from your career or your hobbies.

The UI is consistently unfriendly and getting worse with each change. It's a very busy, brightly colored (toddler friendly color scheme) chat tool with so-so voice chat functions which seems to be progressively getting less stable than Skype for Business (a bar so low that they have to try very hard to be that bad).

They've been introducing more and more "features" to get in the way, such as mandatory channels, the emoji that is mandatory, unprofessional plugins that they encourage you to use, non-chronological order discussions in the same channel, etc. Almost all of this just worked fine if you used their IRC or XMPP gateway. Except -- they're shutting that down precisely because they don't support those features.

The security implications of third party stored communications that you cannot delete are also huge, making it unsafe to use in the enterprise unless you pay for it and have an explicit delete policy.

The company is not responsive to feedback, showing consistent arrogance especially on user accessibility for those who have specific needs like their fonts.

Slack is a leading team communication platform designed for structured, real-time collaboration. It organizes conversations into channels, making it easy to separate topics, projects, or departments while keeping everything searchable and accessible.

It really shines in professional environments thanks to its integrations (Google Drive, Trello, etc.), file sharing, and automation capabilities. Messaging is fast, reliable, and well-suited for both async and real-time work.

Cons: Can become cluttered with too many channels, and the free plan has limitations on message history and features.

Verdict: A top-tier solution for team communication and productivity, especially for businesses that rely on organized workflows and integrations.

Easy and versatile. Connects to everything. Couple things I'd like them to improve: make slack connect easier to use, and improve the process of inviting free single channel members. Our team keeps inviting people as members instead because its a little clunky. Otherwise SUPER HAPPY.

It’s a great tool for teams, especially remote ones. It helps keep work discussions organized, but it takes some effort to manage notifications and avoid getting sidetracked.

If you want to use a free plan, for example to launch a community, I would not advise Slack. Every semester they implement a new constraint to limit their tools to free-plan users.

Works nice on multiple devices. Linux support out of the box.

What is Slack?

Slack is a unified communication platform built with an optimized workflow to keep modern teams focused and productive. A familiar chat interface facilitates discussions while advanced features are easily exposed based on context. Hover over a message to see more options such as emoji reactions, sharing and pinning features and more. A navigation bar provides easy access to key features including a powerful search to find important discussions, files and more.

Conversations are organized across dedicated Channels, neatly arranged in a responsive sidebar with collapsible sections. These Channels are highly configurable and allow for flexibility in working with various teams but can also be shared externally, making it easy to hold discussions with partners and clients.
