How to use

Paste a cURL command from your terminal, browser DevTools, or API documentation into the input area. Pastefix instantly parses it and generates equivalent code in your chosen language — select from Python, JavaScript, Go, Rust, PHP, and more using the dropdown. Click "Explain with AI" to get a line-by-line explanation of what the cURL command does and how the generated code works.

What this tool does

Pastefix's cURL Converter parses any cURL command, extracts the HTTP method, URL, headers, and body, then generates clean, idiomatic code in 13 programming languages. It handles complex flags like --data, -H, -X, --compressed, and authentication headers.

Common use cases

Converting API examples from documentation into your project's language
Translating browser DevTools "Copy as cURL" into production code
Generating HTTP client code for Python requests, JavaScript fetch, Go net/http, and more
Understanding complex cURL commands with multiple headers and authentication
Quickly prototyping API integrations without writing boilerplate from scratch

Frequently Asked Questions

How many languages are supported?

Pastefix converts cURL to 13 languages: Python (requests), JavaScript (fetch), TypeScript (axios), Go (net/http), PHP (cURL), Ruby (Net::HTTP), Java (HttpClient), C# (HttpClient), Rust (reqwest), Swift (URLSession), Kotlin (OkHttp), R (httr), and Dart (http).

Does it handle authentication headers?

Yes. Pastefix correctly parses -u (basic auth), -H "Authorization: Bearer ..." headers, and cookie flags, then generates the appropriate authentication code for each target language.

Can I paste multi-line cURL commands?

Yes. Commands with backslash line continuations (\) are fully supported, which is common when copying from documentation or terminal history.

Is this secure for commands with API keys?

The cURL parsing happens entirely in your browser. Your commands and API keys are never sent to a server unless you click "Explain with AI."
