HTTP Request Builder
Build HTTP requests visually and generate code in cURL, JavaScript, Python, Go, Rust, or PHP. The reverse of cURL to Code.
About HTTP Request Builder
- Build HTTP requests visually — set method, URL, headers, query parameters, auth, and body without writing code.
- Generate code in 6 languages: cURL, JavaScript (fetch), Python (requests), Go (net/http), Rust (reqwest), and PHP (curl).
- Supports Bearer tokens, Basic Auth, and API key authentication in headers or query parameters.
- This is the reverse of cURL to Code — build a request visually instead of parsing a command.
- Everything runs in your browser — no data is sent over the network.
Why generate cURL commands visually?
cURL has over 200 command-line flags, and constructing complex requests with multiple headers, authentication, and JSON bodies is error-prone. A visual builder eliminates quoting issues, flag typos, and ensures proper escaping. The generated command is ready to paste into a terminal, CI/CD pipeline, or API documentation.
# Simple GET request
curl -X GET "https://api.example.com/users"
# POST with JSON body and auth
curl -X POST "https://api.example.com/users" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer eyJ..." \
-d '{"name": "John", "email": "john@example.com"}'Common cURL flags
-X sets the HTTP method, -H adds a header, -d sends a request body, -u provides basic auth credentials, -o saves output to a file, -L follows redirects, and -k skips SSL verification. The visual builder handles all of these through form fields, so you do not need to remember the flags.
Frequently Asked Questions
How do I send a POST request with cURL?
Use -X POST with -d for the body and -H for the Content-Type header. For JSON: curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' URL. The visual builder above generates this automatically.
How do I add authentication to a cURL command?
For Bearer token: -H "Authorization: Bearer TOKEN". For Basic auth: -u username:password. For API key: -H "X-API-Key: KEY". The visual builder supports all three auth types.
