Specothesis

Captures API calls from a Playwright browser session and exports them as an OpenAPI spec.

Desktopfreeglobal

Specothesis is a free, open-source CLI tool that records API calls from a real Playwright browser session and instantly generates an OpenAPI spec, a regression test workflow, curl scripts, and a coverage report — with no proxy or certificate setup required. It's built for developers who want to reverse-engineer accurate API documentation and tests from how an app is actually used, instead of writing an OpenAPI spec by hand.
