What programming languages and libraries does curlconverter.com support?

Updated

curlconverter.com converts a pasted curl command into code for a long list of languages, libraries, and formats. The site groups its output options under a Language: selector and shows the full set as a flat list. If you need Python, JavaScript, Go, Java, PHP, Ruby, Rust, Swift, C, C#, or a handful of non-code formats like HAR and Wget, the tool almost certainly covers it.

Full list of supported targets

The site lists these options (grouped here for readability — the site itself presents them as one list):

Category Supported targets
Python Python + Requests, Python + http.client
JavaScript JavaScript + fetch, JavaScript + jQuery, JavaScript + XHR
Node.js Node.js + Axios, Node.js + Got, Node.js + Ky, Node.js + node-fetch, Node.js + request, Node.js + SuperAgent, Node + http
Java Java + HttpClient, Java + HttpURLConnection, Java + jsoup, Java + OkHttp
PHP PHP + cURL, PHP + Guzzle
Ruby Ruby + Net::HTTP, Ruby + HTTParty
R R + httr, R + httr2
PowerShell PowerShell + Invoke-RestMethod, PowerShell + Invoke-WebRequest
Go Go
Rust Rust
Swift Swift
C C
C# C#
Other languages Ansible, Clojure, ColdFusion, Dart, Elixir, Julia, Kotlin, Lua, MATLAB, Objective-C, OCaml, Perl
Non-code formats HAR, HTTP, HTTPie, JSON, Wget

How the output is tailored

Each target produces a code snippet written in that language's or library's own idioms, not a generic template. For example, selecting Python + Requests yields something like:

import requests

response = requests.get('http://example.com')

The same curl command rendered for JavaScript + fetch, Node.js + Axios, or PHP + Guzzle will use those libraries' specific call signatures and options. This is the main reason to pick a target that matches your actual stack rather than a generic HTTP client.

Practical notes

  • Formats like HAR, HTTP, HTTPie, Wget, and JSON are useful when you want to move a request between tools rather than into application code.
  • The list is broad but not exhaustive. If your syntax is correct and the tool still fails, the site directs you to open a new issue on GitHub.
  • Getting a curl command to convert: in Chrome, open DevTools → Network tab, right-click a request, choose Copy → Copy as cURL (or Copy as cURL (bash)), then paste it into the curl command box. The same flow works in Safari and Firefox with slightly different menu labels.
  • Sensitive data warning: a copied curl command can contain cookies or other credentials. The site warns that sharing someone your cookie for a website is like sending them your password, so review the command before pasting it anywhere public.
