In our organization we are looking for Stack exchange / Reddit / HN like clone that can used for "discussion threads on some technical topics". Any suggestions. We use Teams chat but UI for this purpose is not useful.
The software is QPixel. It was built specifically to be an open-source discussion system a la Stack Exchange.<p>The largest public instance of it that I know of is codidact.com; codidact.org is the sponsoring organization.<p><a href="https://github.com/codidact/qpixel" rel="nofollow">https://github.com/codidact/qpixel</a>
In the bioinformatics sphere there is this MIT-licensed Stack Exchange clone: <a href="https://github.com/ialbert/biostar-central" rel="nofollow">https://github.com/ialbert/biostar-central</a>
Codidact is a literal direct competitor to StackExchange, and it's open-source: <a href="https://codidact.org/" rel="nofollow">https://codidact.org/</a>
I explored this a bit and found there is a threshold of "too many tools" where people won't follow things on yet another thing that sends them notifications.<p>I think the magic number is 4: email, chat, wiki, tickets - we don't do much email so more like 3. The problem is none of those are good at longer technical discussions. With chat, threads beyond a day or so in the past are clunky to revive and follow. Wiki is better at finalized docs, tickets are short lived and any technical discussion should be settled by the time someone is working an item.<p>Really curious if others have found solutions.
Are you looking for something hosted by another organization? I'd say just use the old version of Reddit from when it was still open source as long as you're willing to self-host (<a href="https://github.com/reddit-archive/reddit/wiki/Install-guide" rel="nofollow">https://github.com/reddit-archive/reddit/wiki/Install-guide</a>). I believe that is what Less Wrong originally did. The features that Reddit has added since don't seem useful to me anyway.
For a Stack Exchange-alike, the ROS project hosts one at <a href="https://answers.ros.org" rel="nofollow">https://answers.ros.org</a> which is powered by Askbot (<a href="https://askbot.com/" rel="nofollow">https://askbot.com/</a>), which <i>says</i> it is an open source Django app, but I didn’t see the code at a quick glance.
The Lobsters codebase is available, it's a straightforward Rails app with few dependencies: <a href="https://github.com/lobsters/lobsters" rel="nofollow">https://github.com/lobsters/lobsters</a>
I used this about a decade ago. No complaints.

<a href="https://github.com/LemmyNet/lemmy" rel="nofollow">https://github.com/LemmyNet/lemmy</a><p>"... Lemmy is similar to sites like Reddit, Lobste.rs, or Hacker News: you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the Fediverse."
