cURL vs Fetch API

cURL is a command-line tool for HTTP requests, while fetch() is a browser-native JavaScript API. This converter helps you translate between the two when migrating from terminal-based testing to in-browser JavaScript code.

  • cURL: Great for terminal testing, API debugging, and scripting.
  • Fetch API: Browser-native, Promise-based, integrates with JavaScript apps.

How to Use

  1. Paste a cURL command into the input editor.
  2. Click Convert to Fetch to generate the fetch() equivalent.
  3. Copy the fetch() call for use in your JavaScript/TypeScript project.
