How many API bugs are you missing?
Focus on delivering value with your API. Not debugging it.
Our Open Source core is trusted by industry leaders

Run thousands of test scenarios based on your API specification and ensure your API works as expected.
Application crashes
Learn what payloads make your API crash, corrupt the database or hang forever.
Up-to-date API documentation
Never worry that your API consumers will use an incorrect specification or outdated payload example.
Instant debugging
Get a detailed failure report with a single cURL command to reproduce the problem immediately.
Integrate into your CI
Easily add API fuzzing into your pipeline and reveal whether you can deploy safely.
“Schemathesis is the best tool for fuzz testing of REST API on the market. We are at Red Hat use it for examining our applications in functional and integrations testing levels.”
Find bugs in seconds
Get meaningful and actionable results without spending time on writing tests. Schemathesis automatically parses the API schema and generates test cases that thoroughly verify your API behavior.
Keep your API up to date
Syncing your API with the specification and tests is time-consuming and error-prone. Schemathesis reads your API schema each time and updates the tests, so you can focus on building your product instead.
Test complex workflows. Automatically
Schemathesis automatically infers relations between different API operations and runs thousands of API call sequences against your API. Schemathesis runs an unexpected sequence of API calls and finds a crash before your users do.
