Free until we catch a meaningful issue in 30 days

Catch breaking API changes before they hit prod.

We watch your third‑party APIs (OpenAI, Stripe, Slack, Shopify, Twilio, GitHub, Notion, Anthropic), classify diffs, run nightly smoke tests, and fail PRs when something risky lands.

“We prevent outages and surprise breakages from upstream API changes by detecting risky changes early, running nightly smoke tests, and blocking unsafe merges.”

FAQ

Is it noisy?
No. We block only on golden-test failures or breaking changes on your declared used surfaces. Everything else is informational.
What do you store?
Diffs + test statuses. No request bodies by default. You can run wholly on your infra via GitHub Actions/Pages.
Will it slow developers down?
The PR gate triggers only on high-signal events. You control policies (minSeverity, usedSurfaces, suppressions).
How fast is setup?
About 3–10 minutes. Connect Slack + two provider keys (e.g., OpenAI, Stripe), merge the config, and you’re live.
