ApiLens
Automatically generate versioned API snapshots on every merge. Explore changes between any two versions in a UI with color-coded diff highlighting. Built for FastAPI + TypeScript teams.
Features
- Automatic snapshots — captures your spec on every merge to
main; skips if nothing changed - Visual diff viewer — color-coded UI showing new, removed, and modified endpoints with field-level detail
- PR comments — posts a Markdown summary of API changes on every pull request
- AI prompts — one-click copy of prompts to help update frontend TypeScript types
- Zero integration — no changes to your FastAPI app; runs completely standalone
Install
pip3 install "openapi-lens[serve]"
Usage
apilens serve
The viewer requires snapshots to be generated via GitHub Actions workflows. For full setup instructions, workflow templates, and configuration, see the GitHub repository.
