What is Pico API?

Pico API is a lightweight HTTP client and REST API testing tool that runs as a Chrome extension. Send requests, inspect responses in a JSON tree, and watch SSE and chunked responses stream in live — no account, no workspace, no cloud sync. Includes environment variables, pre/post-request scripts with a Postman-style pm API (pm.test, pm.sendRequest), cURL / OpenAPI / ApiFox import, and copy-as-cURL export. All data stays local in your browser; no analytics. Open source (MIT).
