How to Use the cURL to Code Converter

  1. Copy your cURL command — from browser DevTools, Postman, API docs, or your terminal.
  2. Paste it into the left panel — multi-line commands with backslash continuation are supported.
  3. Select your target language — Python, JavaScript fetch, Node.js axios, Go, or PHP.
  4. Copy the generated code — paste it directly into your project and start using it.

Supported cURL Flags

The converter handles the most common cURL options used when working with HTTP APIs:

  • -X, --request — HTTP method (GET, POST, PUT, PATCH, DELETE, etc.)
  • -H, --header — request headers (can be repeated multiple times)
  • -d, --data, --data-raw — request body for POST/PUT/PATCH
  • -u, --user — basic authentication (username:password)
  • -F, --form — multipart form data
  • -b, --cookie — cookies to include in the request
  • -L, --location — follow redirects
  • -k, --insecure — skip SSL certificate verification

Language Comparison

Python requests

The requests library is the de facto standard for HTTP in Python. It automatically handles JSON serialization, URL encoding, session management, and redirects. Install with pip install requests. The library's API is clean and readable: requests.get(url, headers=headers) for simple requests, or requests.post(url, json=data) for JSON payloads. The requests library is the right choice for data science scripts, automation, CLI tools, and any Python application making HTTP calls.

JavaScript fetch

The fetch() API is built into all modern browsers and Node.js 18+. It returns Promises and integrates naturally with async/await. Unlike axios, fetch does not automatically throw on HTTP error codes — you must check response.ok or response.status. No installation is required, making it ideal for browser-side scripts and modern Node.js applications that want zero external dependencies.

Node.js axios

Axios is a popular third-party HTTP client for Node.js and browsers. It automatically parses JSON response bodies, throws errors on 4xx/5xx responses, and supports request/response interceptors for cross-cutting concerns like authentication and logging. Install with npm install axios. Axios is a common choice in Express.js backends, CLI tools, and any project already using npm.

Go net/http

Go's standard library net/http package provides a complete HTTP client with no external dependencies. The generated code creates an http.NewRequest, sets headers, and uses http.DefaultClient.Do to execute the request. Go's explicit error handling pattern makes the code more verbose than Python or JavaScript but ensures errors are never silently swallowed. No install needed — net/http is part of the Go standard library.

PHP cURL

PHP has built-in cURL support via the curl_init() family of functions. The generated PHP code uses idiomatic cURL options (CURLOPT_URL, CURLOPT_HTTPHEADER, CURLOPT_POSTFIELDS) and properly closes the handle with curl_close(). This pattern works in any PHP environment where the curl extension is enabled (which is most shared hosting and all modern PHP installations).

Frequently Asked Questions

The converter parses the most commonly used cURL flags: -X (method), -H (headers), -d/--data/--data-raw (request body), -u (basic auth), -F (form data), -b/--cookie (cookies), -L (follow redirects), -k/--insecure (skip SSL), and more. The URL is auto-extracted as the bare argument.
The Python requests library is higher-level than cURL. It handles JSON parsing, session management, cookies, redirects, and authentication with less code. cURL is great for quick one-liners and shell scripts; requests is better for applications and data pipelines that need to process responses programmatically.
fetch() is a built-in browser and Node.js API. It does not automatically parse JSON or throw on HTTP error status codes. axios is a third-party library that automatically parses JSON responses and throws on non-2xx status codes. axios is more batteries-included; fetch requires no install.
If the -d or --data flag contains a JSON string and Content-Type is application/json, the converter generates idiomatic JSON handling code: json= keyword argument in Python requests, JSON.stringify() in fetch, and json object in axios.
No. The cURL converter runs entirely in your browser. Your commands, headers, API keys, and request bodies never leave your machine. There is no server, no logging, and no data storage.
