What XHRScribe does
XHRScribe is an API testing Chrome extension that records the real network calls your application makes — every XHR and fetch request — and uses AI to convert them into ready-to-run API tests. Because the tests are built from real traffic, the URLs, headers, request bodies and expected responses reflect how your app actually behaves, not a hand-guessed approximation.
How to generate API tests from network traffic
Hand-writing API tests means re-typing endpoints, headers and payloads you can already see in DevTools. XHRScribe removes that step:
- Record — open XHRScribe and use your app normally; it captures the XHR/fetch calls.
- Generate — AI turns the captured requests into test cases with payloads, headers and assertions.
- Run and reuse — export the tests for regression and contract checks instead of writing each request from scratch.
Who it's for
Backend and QA engineers who need API regression coverage fast, and anyone tired of copying request details out of the Network tab. It pairs well with functional test design from QAtalyst and code-level integration tests from APItiser. Free on the Chrome Web Store; works in any Chromium browser.
FAQ
Does it write payloads and assertions for me? Yes — they're generated from the captured traffic, so you don't hand-write requests.
How is it different from APItiser? XHRScribe builds tests from observed network traffic; APItiser generates integration tests from your code.
Is it free? Yes, free on the Chrome Web Store.
