    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.

Comments and Reviews

   
 Post comment/review
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 great communication and collaboration tool and channels make it easy to group topics of conversation. However, it has it's quirks which can be quite annoying as an everyday user.

it is a scam. i know ppl who like iPhones or dislike using a brain will not like this comment, but lets be real: slack is a scam.

create an account with any fakemail, create a workspace and channel, add ANYONES emailadress, invite a second and third user user to the same space. the third user can spam the the other invited user and there is NOTHING you can do about it.

Just paste 100 images in a direct chat and no matter if the user has ever used slack...they will send reports and other spam to the user.

Sure you can hate Slack and CEO Denise for illegal dataexfiltration when she was at salesforce. or you could argue that training an AI on your company talk is not a good idea...but that wont stop the iPhone users still.

so: SLACK is a scam. Now you know.

Also I remember when ppl said mySpace isnt dead, or facebook...because they got around on the plattform.

the app is crap and so is their very poorly written webinterface that only works in spyware like Chrome but wont in Firefox.

But ppl will insist it is "a g00d mAssageR" because they use it. It is not.

So if you still use Slack you might wanna ask yourself if it was a smart idea to keep on using windows, myspace, turbotax and so on...OR if you are just weak.

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.
