Project mention: Discord to Start Showing Ads for Gamers to Boost Revenue | news.ycombinator.com | 2024-04-01> Tell me another platform that is free, has realtime chat, voice and video, has stable service, allows sharing images and other media, with good ownership management... and is open source.
Mattermost: https://mattermost.com/
Rocket.Chat: https://www.rocket.chat/
Nextcloud Talk: https://nextcloud.com/talk/
Self hosting and some assembly required. I've run all of them on cheap VPSes to explore a Slack/Discord replacement, neither was mindblowing but all of them seemed okay (Nextcloud's offering was rather barebones, though).
Audio and video support varies because getting those right is challenging, at best you'd just integrate with something like Jitsi, that one's actually pretty good for meetings and such: https://jitsi.org/ and has a cloud version too: https://meet.jit.si/ (yet people still go for Zoom and it's odd UI/UX choices)
I actually rather liked forums back in the day, but I guess nobody will be setting up that many phpBB instances in the current year, though projects like Discourse also seem promising: https://www.discourse.org/
I don't think many people at all will be leaving Discord, due to how entrenched the platform is (network effect): if you want people to help you with what you're working on, you go where they are, not vice versa.
Really neat. I was mainly curious to know when they are planning to release the self hosted docker versions of Penpot 2.0. Looks like its coming in the next couple days hopefully [1].
