Every drifting particle above is an upstream breaking change. mendapi watches provider changelogs, scans your codebase entirely on your machine, and shows exactly what breaks — file and line — before production does.
The scanner executes locally or in your CI and makes zero network calls by default. Our test suite mechanically enforces that no networking primitive exists in the scan path.
If you opt in to hosted reporting, only a whitelisted payload leaves: file names, line numbers, symbols. Snippets and source are structurally impossible to upload. Secrets are redacted on every path.
The scanner is AGPL-licensed. Every claim above is a grep away. Enterprise runs fully self-hosted — your infrastructure, your rules.
We monitor 20+ providers — Stripe, OpenAI, AWS, Shopify, and more — across release feeds and changelogs, classifying every change: breaking, deprecation, additive.
Run npx mendapi scan. In under 30 seconds you get file-and-line impact: which breaking changes actually hit your code, with confidence levels that earn your trust.
Run mendapi fix for a local diff preview built from official migration guides. Review it, apply it, ship it. No surprise pull requests.

Payment APIs break in minor-looking releases: a renamed controller, a reworded enum, a dropped response field. mendapi tracks each one at the endpoint level with audited auto-fix packs — built for teams a regulator can ask about.
Each change in our database records the upstream announcement, spec diff or SDK release it came from — audit answers are one link away.
Enterprise runs the full stack inside your firewall with your own compute and LLM keys. See the security model.
