API Abuse Scenarios

Generate test cases for API robustness

APIs need testing against abuse and logic flaws, not just the happy path. This tool generates test cases for API rate limiting and logic flaws, so you can check your own API holds up against the misuse it will face.

Why testing for abuse matters

An API tested only with valid, well-behaved requests will pass every test and still fail in production, where clients send too many requests, malformed input, out-of-order calls, and attempts to bypass business rules. Generating test cases that probe rate limiting and logic flaws, the boundaries and misuse patterns, surfaces the weaknesses before an attacker or a buggy client does. This is defensive testing of your own API, hardening it against the realities of exposure rather than assuming clients behave.

Test against reality

It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project. Because it works client-side, you can use it on private code and data without anything leaving your machine.
