Talkyard Alternatives
Talkyard is described as 'Help each other — with the main features from StackOverflow, Discourse, Slack, Reddit, and Disqus' and is a Q&A service in the social & communications category. There are four alternatives to Talkyard for a variety of platforms, including Online / Web-based, Self-Hosted solutions, Python, Django and Android. The best alternative is Stack Overflow. It's not free, so if you're looking for a free alternative, you could try Scoold or OSQA.
Stack Overflow, part of Stack Exchange, is a free, community-driven, reputation-based Q & A site for computer programmers. No membership is required to ask questions or provide answers to questions by others.
Scoold is inspired by StackOverflow and implements most of its features. You can ask and answer questions, upvote and downvote posts, earn badges and reputation. Each edit creates an new revision, making it easy to follow the history of edits. Scoold is optimized for the cloud.
