Frumle vs Stoplight

Frumle wins because the docs that matter describe the code you shipped. Stoplight keeps you in design-first OpenAPI land while production drifts. Frumle documents the real API, answers questions with AI, and connects coding agents.

Why teams move

Document the implemented API, not a design artifact that went stale
AI Q&A for implementers and consumers
Agent Connect for AI IDEs and coding agents
CLI + GitHub Actions keep docs current after every intentional update
Import OpenAPI once if you are leaving a design-first stack

Leave it behind

Where Stoplight fails

Design-first specs diverge from production code
OpenAPI editing does not give you living docs from source
No Agent Connect for AI coding tools
No Frumle-class project-grounded AI assistant
Extra process for teams that already have working APIs in code
