    Other than Quora, it's like the only one on this list that actually plays the same role Stack Overflow plays. It's a reputation-based question and answer site (or collection of sites/communities) organized around a central topic

    Codidact implements features that are impossible on Stack Overflow, based on what the community needs. The community is central on Codidact and the platform is open-source, so you can use Codidact's network or set up your own if you want to run things differently.

    Similar to Codidact in that they directly aim to be an alternative to Stack Exchange. Unlike Codidact, it's mostly restricted to tech topics. Good alternative
