What Apache Answer Does
- Hosts a Q&A site with questions, answers, voting, and accepted answers

Architecture Overview
Apache Answer is a Go backend serving a React single-page frontend. It stores data in SQLite by default, with optional MySQL or PostgreSQL support. The application ships as a single binary or Docker image. A plugin system allows extending functionality without forking the core, and an embedded search engine handles full-text queries.
Self-Hosting & Configuration
- Deploy with Docker using a single command and a mounted data volume
- Run the setup wizard on first boot to configure the database, admin account, and site name
- Switch to MySQL or PostgreSQL by editing the database connection string in the config
- Install plugins from the admin panel to add OAuth login, email notifications, or S3 storage
- Place behind a reverse proxy for HTTPS termination and custom domain routing
