OSQA is described as 'is the free, open source Q&A system you've been waiting for. Your OSQA site is more than just an FAQ page, it is a full-featured Q&A community. Users earn points and badges for useful participation, and everyone in the community wins' and is an app in the Education & Reference category. There are more than 10 alternatives to OSQA for a variety of platforms, including Online / Web-based, Self-Hosted solutions, Android, iPhone and Mac. The best alternative is Stack Overflow. It's not free, so if you're looking for a free alternative, you could try Stack Exchange or Question2Answer. Other great apps like OSQA are Scoold (Free, Open Source), Codidact (Free, Open Source), Hypersay (Free Personal) and Bitfortip (Free).
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.
Hypersay is a platform for interactive presentations that massively increase engagement. Keep your audience engaged with polls, questions, private notes and live slide sharing. Store, enrich & deliver presentations from your cloud.
Askbot is a Q&A system, like StackOverflow, Yahoo Answers and some others. Askbot is based on code of CNPROG, originally created by Mike Chen and Sailing Cai and some code written for OSQA. Askbot is open-source and can be self-hosted for free; hosting plans are paid.
