Why this tool exists

Vultio cURL Converter translates cURL commands into ready-to-run HTTP client code for Python, JavaScript, Go, PHP, and Ruby — entirely in your browser.

It is the fastest way to turn a request copied from browser DevTools or API documentation into production-ready code without manually translating headers, auth, and body serialization.

Common use cases

Convert a cURL command from API docs into Python requests code for a backend integration.
Translate a failing request from browser DevTools into JavaScript fetch to reproduce it in a test.
Generate Go net/http code from a cURL prototype before wiring it into a service.
Turn a developer-shared cURL command into PHP curl or Ruby net/http for a framework integration.
Quickly verify that auth headers and body encoding translate correctly across languages.

Example input / output

POST with JSON body

Input

curl -X POST https://api.example.com/users -H 'Content-Type: application/json' -d '{"name":"Alice"}'

Output

import requests

url = "https://api.example.com/users"
headers = {"Content-Type": "application/json"}
payload = '{"name":"Alice"}'

response = requests.post(url, headers=headers, data=payload)

GET with Bearer token

Input

curl https://api.example.com/me -H 'Authorization: Bearer abc123'

Output

const response = await fetch("https://api.example.com/me", {
  method: "GET",
  headers: { "Authorization": "Bearer abc123" }
});

Common errors

Input must start with "curl".

Cause: The pasted text does not begin with the curl command.

Fix: Make sure to copy the full cURL command including the "curl" keyword at the start.

No URL found in cURL command.

Cause: The parser could not identify a URL (a token not prefixed with a dash).

Fix: Check that the URL is present and not accidentally wrapped in a flag.

Frequently asked questions

What is a cURL converter online?

A cURL converter takes a cURL command — the kind you copy from browser DevTools or API documentation — and outputs equivalent HTTP client code in your language of choice. No manual translation needed.

Which languages does the cURL converter support?

The converter outputs Python (requests), JavaScript (fetch), JavaScript (axios), Go (net/http), PHP (curl), and Ruby (net/http). Select the target language before converting.

What cURL flags are supported?

The parser handles -X (method), -H (headers), -d/--data (body), --user (Basic Auth), --oauth2-bearer (Bearer token), --cookie, --insecure, -L (follow redirects), and --max-time (timeout).

How do I get a cURL command from my browser?

In Chrome or Firefox DevTools, open the Network tab, right-click any request, and choose "Copy → Copy as cURL". The result can be pasted directly into this converter.

Is my cURL command sent to a server?

No. All parsing and code generation runs client-side in your browser. Your cURL commands — which may contain credentials or tokens — never leave your machine.
