Key insight: Nobody has built the GitHub Actions equivalent for API contracts — a simple, plug-and-play gate that prevents deployments when schemas break existing consumer expectations, and that's worth real money to teams shipping APIs 50+ times a month.

The Problem

Backend teams deploy API changes that break frontend and third-party integrations, but there's no automated way to catch schema mutations before they go live. Developers manually compare OpenAPI specs or Postman collections, and half the breaking changes only surface after production incidents.

Target Audience

Backend teams at mid-market SaaS companies, integration-heavy platforms, and API-first startups using CI/CD pipelines (Stripe, Twilio, etc. competitors).

Why Now?

API-first architectures are standard now, and CI/CD adoption means teams run deployments dozens of times per week. The pain of manual change reviews scales badly.

What's Missing

Existing tools (Swagger/OpenAPI editors) show diffs but don't automate CI integration. There's no 'GitHub Status Check for API schemas' that blocks bad deployments.
