    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

    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.
