HTTP, GraphQL & WebSockets
Only for Mac
$1.99
Mac
A private, native macOS API workspace. Build, test, monitor, and share requests. Without an account, cloud sync, or telemetry.
Curlew is a fast, native API client for macOS—built for developers who want a focused workspace for HTTP, GraphQL, and WebSocket requests.
Keep your work private: no account, cloud sync, or telemetry. Your workspace is a readable local JSON file, while secrets and tokens stay in your Keychain.
Build and explore APIs
• Create HTTP requests with query parameters, headers, JSON, XML, form, multipart, and GraphQL bodies.
• Connect to WebSockets and inspect live messages; stream Server-Sent Events as they arrive.
• Browse GraphQL schemas through introspection and insert fields directly into your query.
• Import cURL commands, Postman collections, and OpenAPI specifications; export Postman collections and share code as cURL, Swift, Python, or JavaScript.
Test with confidence
• Use Bearer, Basic, API key, OAuth 2.0 with PKCE, client certificates, cookies, and Keychain-backed secret variables.
• Run collections in order with assertions, response-value extraction, and clear pass/fail results.
• Repeat requests to see latency statistics, compare responses, search JSON paths, and inspect HTML, images, XML, cookies, headers, or binary data.
Work faster
• Organize collections, environments, request tabs, notes, history, and keyboard shortcuts in one lightweight workspace.
• Mock an entire collection on localhost while the backend is still taking shape.
• Monitor important endpoints from the menu bar and receive a notification when an assertion starts failing.
Curlew is a private, dependable companion for building, debugging, and checking the APIs behind your next release.
