DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Docusaurus, the case for Astro, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Docusaurus
99.4 / 100- 66,550+ GitHub stars as the definitive React and MDX documentation platform maintained by Meta
- Out-of-the-box versioning allows maintaining documentation for multiple software release lines simultaneously
- Cuts commercial GitBook and ReadMe invoices by 98.3% ($25/mo self-hosted Jamstack vs $1,450/mo SaaS)
When to Pick Astro
99.2 / 100- 63,360+ GitHub stars delivering zero client-side JavaScript by default for blazing-fast documentation load times
- Official Starlight theme provides turnkey search, internationalization, and responsive navigation out of the box
- Supports mixing React, Vue, Svelte, and Solid components in the exact same documentation pages
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
