Schemathesis automatically generates thousands of test cases from your OpenAPI or GraphQL schema and finds edge cases that break your API.
- 💥 500 errors that crash your API on edge case inputs
- 📋 Schema violations where your API returns different data than documented
- 🚪 Validation bypasses where invalid data gets accepted
- 🔗 Integration failures when responses don't match client expectations
