Documentation

Documentation tools are for writing docs people actually read — the kind of work every indie hacker eventually hits and would rather not build from scratch. 7 tools are listed here, each picked and written up individually rather than pulled from an affiliate feed. Docusaurus is usually the first one people try: free, open-source, and battle-tested by half of GitHub's OSS projects — the safe default for docs-as-code. GitBook takes a different angle — the default pick when you want docs that read like a real product, not a wall of Markdown. And Mintlify is worth a look too: point it at a GitHub repo and get a polished, AI-searchable docs site without touching a CSS file. Every listing below includes the actual tradeoff, not marketing copy, so you can pick based on what you're building instead of what ranks highest in a sponsored roundup elsewhere.
