cURL to Code Converter: Instant In-Browser Translation

Web browser Developer Tools allow developers to capture any live HTTP request executed by a web application and copy it as an executable cURL command. ToolMono is optimized to parse these complex, multiline DevTools commands directly.

ToolMono generates modern, standard async/await JavaScript code utilizing either the browser-standard window.fetch API or the axios library.

const response = await fetch("https://api.example.com/v1/users", {
  method: "POST",
  headers: {
    "Accept": "application/json",
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_TOKEN"
  },
  body: JSON.stringify({
    name: "Alex Rivers",
    active: true
  })
});

const data = await response.json();
console.log(data);

• JSON Payload: Formats JSON objects cleanly with JSON.stringify(...).
• Multipart Form Data: Uses new FormData() and automatically omits explicit Content-Type header so the runtime computes the boundary string.
• Response Handling: Inspects Accept and Content-Type headers to determine whether to call response.json() or response.text().

Python developers frequently translate cURL commands into requests or modern asynchronous httpx scripts. ToolMono formats Python dictionaries idiomatically with native boolean casing (True/False) and None.

import requests

headers = {
    "Accept": "application/json",
    "Authorization": "Bearer YOUR_API_TOKEN"
}

json_data = {
    "name": "Alex Rivers",
    "active": True
}

response = requests.post(
    "https://api.example.com/v1/users",
    headers=headers,
    json=json_data
)

print(response.status_code)
print(response.text)

• Native json= Argument: When a request body is valid JSON, Python Requests accepts the dict via json=json_data, automatically managing the JSON serialization and Content-Type header.
• Basic Authentication: Formats credentials as auth=("username", "password") tuples.
• Insecure TLS: Automatically appends verify=False when -k / --insecure is used.

Since Node.js v18.0.0, the Fetch API is available natively in global scope without needing external dependencies like node-fetch or cross-fetch.

ToolMono produces standard Node.js scripts ready for modern ESM (import) and CommonJS environments.

Go code generation uses the standard library net/http package, implementing proper request creation, header assignment, response body closing with defer resp.Body.Close(), and error inspection.

package main

import (
	"fmt"
	"io"
	"net/http"
	"strings"
)

func main() {
	client := &http.Client{}

	var data = strings.NewReader(`{"name":"Alex Rivers","active":true}`)
	req, err := http.NewRequest("POST", "https://api.example.com/v1/users", data)
	if err != nil {
		panic(err)
	}

	req.Header.Set("Accept", "application/json")
	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("Authorization", "Bearer YOUR_API_TOKEN")

	resp, err := client.Do(req)
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	bodyText, err := io.ReadAll(resp.Body)
	if err != nil {
		panic(err)
	}
	fmt.Printf("%s\n", bodyText)
}

The PHP code generator outputs valid, syntax-checked PHP code using the native curl_init() extension with appropriate options: CURLOPT_RETURNTRANSFER, CURLOPT_HTTPHEADER, and CURLOPT_POSTFIELDS.
