When do you need a cURL to code converter?

Developers encounter curl commands everywhere — API documentation, browser DevTools ("Copy as cURL"), Postman exports, Slack conversations, and incident runbooks. Translating a curl command into fetch, requests, or net/http by hand means mapping flags to method calls, headers to dictionaries, and body encoding to language-specific APIs. A converter eliminates that busywork: paste the curl, pick your language, copy the code.

How the converter works

The tool tokenizes the curl command — handling single-quoted strings, double-quoted strings with escape sequences, and line continuations from Unix (\), Windows CMD (^), and PowerShell (`). It then walks the token list to extract the HTTP method, URL, headers, body, authentication, timeouts, and behavioral flags like -L (follow redirects) and -k (skip SSL). The parsed request is passed to a language-specific code generator that produces idiomatic, copy-paste-ready code with proper imports and error handling. Everything runs client-side in JavaScript.

Copy as cURL from browser DevTools

In Chrome, Edge, or Brave: open DevTools (F12) → Network tab → find the request → right-click → Copy → Copy as cURL (bash). In Firefox: Network tab → right-click → Copy → Copy as cURL. In Safari: Develop menu → Show Web Inspector → Network → right-click → Copy as cURL. Paste the result into this tool to get code in any supported language.

Supported languages

  • JavaScript (fetch) — the fetch() Web API with async/await or .then() chains
  • JavaScript (axios) — the axios npm package with async/await or .then()
  • Python (requests) — the de facto Python HTTP client
  • Go (net/http) — standard library, no external dependencies
  • PHP (cURL) — curl_* functions
  • Ruby (Net::HTTP) — standard library, no gems required
  • Java (HttpClient) — java.net.http.HttpClient (Java 11+)
  • C# (HttpClient) — System.Net.Http
  • Rust (reqwest) — most popular Rust HTTP client
  • Swift (URLSession) — Foundation framework
  • Kotlin (OkHttp) — most popular Android/Kotlin HTTP client

Frequently asked questions

It takes a curl command — the kind you copy from API docs, browser DevTools, or Postman — and translates it into equivalent code in your programming language. Instead of manually figuring out how to set headers, body, and auth in fetch or requests, you paste the curl and get runnable code instantly.

Open DevTools (F12) → Network tab → find the request → right-click → Copy → Copy as cURL (bash). Then paste it into this tool. This works in Chrome, Firefox, Edge, and Safari.

JavaScript (fetch and axios), Python (requests), Go (net/http), PHP (cURL), Ruby (Net::HTTP), Java (HttpClient), C# (HttpClient), Rust (reqwest), Swift (URLSession), and Kotlin (OkHttp).

Yes. Basic auth (-u user:pass) is converted to the idiomatic auth mechanism for each language — for example, auth=('user', 'pass') in Python, req.SetBasicAuth() in Go, and an Authorization: Basic header in JavaScript. Bearer tokens in -H "Authorization: Bearer ..." are preserved as-is.

No. Everything runs in your browser. The curl command is parsed and converted entirely client-side — nothing is sent to MockServer or any other server.

The tool runs in your browser, which doesn't have access to the file referenced in the curl command. Form fields with string values (-F "key=value") are converted, but file references are replaced with a placeholder comment.
