curl2code — Convert curl to code in 30+ languages

curl (short for "Client URL") is a command-line tool for transferring data using network protocols such as HTTP, HTTPS, FTP, and many others. It is pre-installed on macOS, most Linux distributions, and Windows 10+. Developers use curl to test APIs, debug HTTP requests, download files, and automate interactions with web services. A typical curl command looks like curl https://api.example.com/users — this sends a GET request and prints the response to the terminal. curl supports virtually every HTTP feature: custom headers (-H), request methods (-X POST), data payloads (-d), authentication (-u), cookies (-b), and file uploads (-F). It is one of the most widely used developer tools in the world, with its syntax serving as a de facto standard for describing HTTP requests in documentation and tutorials.

curl2code is a free, open-source curl-to-code converter that parses a curl command and generates equivalent code in your chosen programming language. It supports over 30 languages — from Python Requests and JavaScript fetch to Rust, Swift, and Ansible. The conversion engine is powered by curlconverter, compiled to WebAssembly and executed entirely in your browser — no data is ever sent to a server. Additional features include AI-powered code explanations (you provide your own API key), Smart Clean to strip noisy headers and cookies, a visual cURL Builder for constructing requests with a form interface, and shareable code snippet links. curl2code is free, requires no sign-up, and works offline after the initial page load.

curl supports all standard HTTP methods. By default, it sends a GET request. To use a different method, pass the -X flag: curl -X POST, curl -X PUT, curl -X DELETE, curl -X PATCH. curl also infers the method automatically in some cases — for example, adding -d (data) switches the method to POST without needing -X. Less common methods like HEAD (-I), OPTIONS, and TRACE are also supported. With curl2code, you can paste any curl command using any HTTP method, and it will generate the correct code for your chosen language — complete with the proper method call, headers, and request body.

curl can send data in any format using the -d or --data flag. For JSON, you typically combine it with a Content-Type header: curl -H "Content-Type: application/json" -d {"key":"value"} URL. For URL-encoded form data, curl uses -d "field=value" — this is the default Content-Type. For multipart file uploads, use -F "file=@document.pdf", which automatically sets the multipart/form-data header. curl2code recognizes all these patterns and generates language-specific code that handles content types, serialization, and encoding correctly. Need to build a complex request from scratch? Try our cURL Builder — it provides a visual form for setting methods, headers, body content, and authentication.

Paste your curl command into the input field on curl2code and select the target language from the dropdown. The tool parses all curl flags — -X (method), -H (headers), -d (data), -u (auth), -F (form uploads), -b (cookies), and more — and generates clean, idiomatic code using the standard HTTP library for that language. For example, Python output uses requests, JavaScript uses fetch, and Go uses net/http. The conversion is instant and runs entirely in your browser. You can also switch between library variants (e.g., Python's requests vs http.client) and use AI-powered explanations to understand the generated code.
