● The Problem

Writing API tests is tedious. Most teams have poor API test coverage. Generating tests from specs manually takes hours per endpoint. Untested APIs break in production.

● The Solution

Import your OpenAPI spec. AI generates a complete test suite: happy paths, edge cases, error handling, and authentication tests. Export to Postman, Jest, or pytest.

Competitive Landscape

Postman has basic test generation. Schemathesis does property-based testing. No tool generates complete, meaningful API tests from specs using AI.

Why Now?

AI understands API patterns deeply. OpenAPI adoption provides structured input. API-first architecture means more endpoints to test.
