Generate Next.js project documentation automatically. Codec8 documents your pages, API routes, data fetching patterns, and deployment config in one pass.
Next.js projects mix frontend pages, API routes, middleware, and static assets in a single repo. Documenting how all of these pieces fit together — especially across the App Router migration — is a nightmare to do manually.
