While looking for Discord alternatives I came across this project which looks like a great alternative for the kinds of Discord servers centered around Open Source projects and organizations. Ones where live chat and voice rooms aren’t the focus.
It’s a combination of forums and knowledge base that would be perfect for this use case.
I think a blurb would be a great idea, especially for your project.
I feel like the biggest hurdle for your project is that the people it speaks to, especially the way you market it (analogues to natural, organic things like plants, the purposeful methodology intrinsic to gardening, as well as the nostalgic throwback to a simpler time of the internet when everything was more hand-made and deliberate) are the same people that will be put off by AI, being that it’s the antithesis of those things.
Making your case for why and how it’s used, (IE Not just vibe-coded slop but something that matters a little more to you) might be enough to keep people on board, and maybe give it an honest try.
