About

API Spector is a free, open-source, local-first API tool for the whole lifecycle in one place: build & test requests (REST, GraphQL, SOAP, WS), mock endpoints with dynamic data, run contract tests (Pact-compatible, bi-directional, can-i-deploy), and monitor live APIs. One tool instead of four. The desktop app is MIT-licensed and free forever, and your work stays on your machine. Optional cloud adds hosted mocks, monitoring, status pages, and a shared contract broker.
