John FastmanDoes everything Slack does AND it's open source. However, it's also self-hosted. This means you have to put in the effort to set it up, but you control your own data, which is a huge advantage to your privacy - your chats and files don't sit on someone else's servers, ready for them or hackers to look at.
10Rocket.Chat comes very close to slack regarding it's core features and handling.

Comments about Element as an Alternative to Slack
because its open source, decentralised, and end-to-end secure. Plus the folks at matrix.org are working to get us out of our communication silos by creating standards for communication interoperability!
decentralised, federated, end-to-end encrypted communication.
this is a open source and free software that is very useful for me
Encrypted, free, open-source, decentralized
It is decentralized and it works with an open standard
