About Stack Overflow
Stack Overflow is a question and answer site for programmers. Anyone can ask a technical question, and the community votes on the best answers.
What it does
Questions are tagged by language, framework or tool, so people can find answers by topic. Users earn reputation by asking clear questions and writing useful answers. The site also has collectives for specific technologies and a business product for sharing internal knowledge across a company.
Key features
- Search answers by tag, language or tool
- Ask questions and get community answers
- Vote on answers to surface the best ones

Who it's for
Developers at all levels who need help with a specific error or concept. Engineering teams use the business product to share internal knowledge, and many developers use the archive of past questions as a reference.
Pricing and good to know
The public Q and A site is free to use with an account, and reading answers does not require one. Business products for internal knowledge are sold separately. Community rules on posting apply to everyone, so read the guidelines before asking a question.
