    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!

    Element is way too buggy and slow. It's actually totally free unlike the description which says it's not free. But, free isn't enough when the software is just buggy and slow.

    Comments about Zulip as an Alternative to Slack
    Comment summary: Zulip is praised for its open-source nature and unique threading model, which many users find superior to Slack's, especially for organizing and categorizing conversations through Streams and Topics. It's particularly beneficial in professional settings with diverse team discussions. Users appreciate its vibrant community and flexibility, offering both self-hosted options and better value plans compared to Slack. Despite not being fully open-source, Zulip provides a robust alternative.

    More than feature parity with Slack, it's better because of Streams and Topics. It offer the same free tier with 10.000 max messages and better paid plans to the hosted version, and also provide the open source self-hosted option to install it on your own server and also remove the max messages limits. 5 stars

    Zulip found the right balance to facilitate asynchronous communication and collaboration. It allows me to participate in several conversation topics without getting overwhelmed and without missing relevant messages. It allows more control over the data and it gives users more control to find their preferred communication and notification setup. It allows me to be away from the chat for 1-2 weeks and still catch up on all relevant discussion threads.

    Comments about Discord as an Alternative to Slack
    Comment summary: Discord is often seen as a more casual, gamer-friendly alternative to Slack, with features like voice support and lower setup complexity. While Discord lacks Slack's integration with external tools, such as GitHub and document editors, it is rebranding to appeal to enterprise users, suggesting potential for broader use. Discord excels in personal and community-oriented use cases, whereas Slack targets business productivity, offering features better suited for that environment.

    Very very similar in terms of use and features. Of course, discord is marketed as for gamers while slack is for teams but usage is almost identical.

    Slack is a project productivity and communication enhancement tool with integrating with other collaborative tools like GitHub, document editors, storage, etc. Discord is for recreational chatting.

    Nextcloud Talk, like most of Nextcloud, is very heavyweight. So if you don't have a very good server, it's going to be very slow (for me it was around 10 seconds to send a single message)
