Rentgen – Automated API bug detection before writing tests

Summary: Rentgen detects API bugs by generating 50–200 edge-case checks from a single cURL command before any tests exist. It runs fully locally without accounts or cloud, focusing on boundaries, invalid data, headers, CORS, enums, and latency to reveal issues early.

What it does

Rentgen creates extensive edge-case tests from one cURL input to identify API failures and unexpected behaviors before formal testing begins.

Who it's for

Developers and QA teams needing early detection of API issues prior to writing manual or scripted tests.

Why it matters

It exposes hidden API problems that occur beyond simple successful requests, improving reliability before QA handoff.
