About this tool
REST Tester for Chrome runs as a page in your browser. REST Tester for Chrome sends HTTP requests from your browser to the API endpoint you enter and shows the status, headers and body of the response.
It is a thin client around the browser fetch API — no proxy and no stored credentials, just the request you configure. The request is sent from your browser straight to the API you name; this site has no backend and never receives it, though that server and your network can see it. Cross-origin calls follow the browser's CORS rules, and a connection is required.
