Open-source StackOverflow-like service

In plain words

Open-source StackOverflow-like service is a question-and-answer platform for developers, launched in 2016. It provides a community-driven space where developers can ask technical questions, share knowledge, and find solutions. The service is open-source, allowing users to self-host or contribute to its development. It's designed for software engineers and programmers seeking peer support and collaborative problem-solving in a format similar to Stack Overflow.
