I’ve noticed question2answer (https://alternativeto.net/software/stackoverflow/?license=opensource) as a first alternative, but I don’t know how to find instance of it focused on programming. There’s a list on their webiste, but very few instances are listed there.
Does anybody know about some libre alternative to Stackoverflow?
