Test
Validate your API responses without writing test scripts. Build assertions visually, validate against JSON schemas, and catch issues before they become problems.
No Code Required
Point-and-click assertion builder. Select what to check, set your conditions, done.
Instant Feedback
See pass/fail results immediately after each request. No separate test run needed.
Custom Schemas
Bring your own JSON Schema. No OpenAPI required - just paste or upload your schema.
Visual Assertions
Build test assertions without writing code. Check status codes, response times, headers, and body content with a simple point-and-click interface. Each assertion shows pass/fail status instantly after every request.
JSON Path Expressions
Validate specific values deep within your JSON responses. Use JSON Path expressions like $.id, $.data[0].name, or $.items[*].price to target exactly what you need to test. Combine with operators like equals, contains, exists, and regex.
Contract Validation
Validate responses against JSON Schema. Upload your own schema or paste it directly - no OpenAPI required. Ensure your API responses match the expected structure every time. Catch breaking changes before they reach production.
Assertions + Contract
Use both approaches together for comprehensive testing. Assertions for quick checks and business logic, Contract validation for structural integrity. See all results at a glance in the response panel.
What You Can Test

- Response time less than, greater than
Headers
- Header exists, not exists
- Header value equals, contains, matches regex
JSON Path
- Path exists, not exists
- Value equals, contains, greater/less than
Body
- Body contains, not contains
- Body matches regex pattern
