Slack brings team communication and collaboration into one place so you can get more work done, whether you belong to a large enterprise or a small business. Check off your to-do list and move your projects forward by bringing the right people, conversations, tools, and information you need together. Slack is available on any device, so you can find and access your team and your work, whether you’re at your desk or on the go.

Use Slack to:
• Communicate with your team and organize your conversations by topics, projects, or anything else that matters to your work
• Message or call any person or group within your team
• Share and edit documents and collaborate with the right people all in Slack
• Integrate into your workflow, the tools and services you already use including Google Drive, Salesforce, Dropbox, Asana, Twitter, Zendesk, and more
• Easily search a central knowledge base that automatically indexes and archives your team’s past conversations and files
• Customize your notifications so you stay focused on what matters

Scientifically proven (or at least rumored) to make your working life simpler, more pleasant, and more productive. We hope you’ll give Slack a try.

What's New

Version 3.2.0

What’s New
• Myriad improvements for the people of Enterprise Grid, including quicker Quick Switching, better proxy support, and direct message draft syncing across multiple workspaces (meaning that whichever workspace you started typing that message in, you can finish in another.)

Bug Fixes
• Unread badges were occasionally unreliable or inconsistent, so we tweaked a few doohickeys to improve them. It worked.
• Smoothed some wrinkles in the loading of Slack calls and boosted general under-the-hood call performance while we were in there.
• We tinkered with the workspace sign-in flow, updating how we handle errors and improving magic link support.
• Copying email links now does what you’d expect (as long as you were expecting it to copy the email link. If you were expecting it to do something like file your taxes for you, you are still out of luck).
• Slack will no longer interrupt macOS when restarting or shutting down.
• After changing displays, pinch-to-zoom gestures will no longer insist on continuing to zoom the app when you pinch.
• Twelve crashes have been fixed. Yes. 12. If you were unlucky enough to experience the full dozen, please accept a) this imaginary medal and b) our sincere apologies.

Editors' Notes

Organize your team communication by topic, task, and project.

Best in the industry by far.


You’d be hard pressed to find a better piece of software, well supported ongoing development, excellent user experience and backed by a powerful set of APIs. Integrations with everything you can ever want or need. An absolute must for collaboration and productivity - unless you like spending your day sending rubbish emails back and forth and think your employees should too! In that case, get the fax machine out!

memory and cpu hog, closed ecosystem


800MB of RAM and a constant 10-50% CPU for a chat client.... typical javascript rubbish.

Developer Response

Thank you for sharing your feedback. We really appreciate it! CPU and memory usage is definitely something we're focused on improving, as we know it could be much better. Our apologies for the poor behavior this is causing.
