{"slug":"best-documentation-platform-for-developer-docs","title":"Best documentation platform for developer docs","question":"What are the best documentation platform for developer docs?","verdict":"As of 2026-07-15, ChatGPT, Claude, Gemini and Grok collectively rank Mintlify #1 for documentation platform for developer docs on ModelsAgree by aggregate score. The models' case: Best overall balance of polished hosted output, docs-as-code workflow, strong MDX components, OpenAPI references, search, analytics, and low maintenance. The models' main caveat: Its managed, opinionated platform is not for teams requiring full infrastructure control or minimal vendor dependence. The strongest alternative is Docusaurus — Full React/MDX customization, powerful plugin ecosystem, native versioning, excellent search and theming, Git-native docs-as-code workflow that aligns. Not unanimous: Grok picks Docusaurus.
