Campfire (the self-hosted group chat) just became free and open source! - Lemmy.World

Hi! DHH (co-founder of Basecamp) announced [https://x.com/dhh/status/1963675999012552970] yesterday that they’re making their group chat software open source and free for everyone to use. This is fantastic news, especially considering this piece of software previously required a $299 payment just to access the codebase (far too expensive, in my opinion). It looks like we now have another excellent open source alternative to Slack and Microsoft Teams [https://openalternative.co/campfire], thanks to this move. I really hope more companies will follow this trend soon. What are your thoughts?

There are some other projects in this space already, with varying levels of open source / selfhostability / features

Zulip and Revolt looked the most promising for Slack and Discord replacements respectively

Zulip — organized team chat

Revolt can’t be considered viable in my mind until the mobile app stops hardcoding the official instance and lets users connect it to selfhosted instances.
