Hookshot - REST API Client & HTTP Request Tester for Developers

Test & debug REST APIs, HTTP requests & webhooks. Import cURL commands, save history. Free API testing tool for developers.

Hookshot is a free, full-featured REST API client and HTTP request tester built right into your browser. Test any API endpoint, debug HTTP requests, and inspect responses — all without leaving Chrome. Whether you're building a REST API, integrating a third-party service, debugging a webhook, or exploring a new API for the first time, Hookshot gives you everything you need in a clean, fast interface. KEY FEATURES: • Full HTTP Method Support — Send GET, POST, PUT, PATCH, DELETE, OPTIONS, and HEAD requests to any URL or API endpoint. • Request Builder — Add custom headers with an intuitive key-value editor. Set request body content as JSON, XML, plain text, or form URL-encoded data. Configure Basic Auth or Bearer Token authentication. • Beautiful Response Viewer — Inspect response status codes (2xx, 3xx, 4xx, 5xx), headers, body content, response time, and payload size. JSON responses are automatically syntax-highlighted with color-coded keys, strings, numbers, booleans, and null values for easy reading. • cURL Import & Export — Paste any cURL command to instantly populate method, URL, headers, body, and authentication fields. Copy your current request as a cURL command to share with teammates or use in scripts. • Request History — Every request you send is automatically saved and searchable. Click any history entry to restore the full request — URL, method, headers, body, and auth. Never lose a request again. • Keyboard Shortcuts — Hit Ctrl+Enter (or Cmd+Enter on Mac) to send requests instantly. PERFECT FOR: → Backend developers testing REST API endpoints → Frontend developers debugging API integrations → QA engineers testing HTTP requests and responses → DevOps engineers testing webhooks and callbacks → Students learning about HTTP methods and REST APIs → Anyone who needs a quick, free API testing tool WHY HOOKSHOT? Unlike heavyweight API clients that require installation and accounts, Hookshot runs entirely in your browser. No signup required, no desktop app to install, no subscription fees. Open a new tab and start testing. Hookshot is lightweight, fast, and privacy-focused. Your request history is stored locally in your browser — nothing is sent to external servers (except the HTTP requests you explicitly send to your own endpoints). SUPPORTED REQUEST TYPES: • GET — Retrieve data from APIs and endpoints • POST — Send data, create resources, trigger webhooks • PUT — Update and replace resources • PATCH — Partially update resources • DELETE — Remove resources • OPTIONS — Check CORS and server capabilities • HEAD — Retrieve headers without body content BUILT FOR DEVELOPERS: Hookshot is designed by developers, for developers. The clean dark-on-light UI is optimized for readability. JSON syntax highlighting makes response inspection effortless. The cURL import/export workflow fits naturally into how developers already work — copy a cURL from browser DevTools, documentation, or Slack, paste it into Hookshot, and you're testing in seconds. Free forever. No limits. No ads. Just a fast, reliable API client in your browser.
