Free online API & webhook testing playground. Send GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests, inspect JSON responses, and fire webhooks in seconds. No install, no account.

Most API tools make you install software, create an account, and share tokens before you can send a single request. API Playground flips that. Open your browser, paste a URL, hit send — done. Full HTTP support, webhook testing for Make.com & Zapier, request history, environment variables, and a beautiful JSON response inspector. 100% free, forever. No hidden plans, no upsells.
