cURL Builder

Build and generate cURL commands for APIs

What is the cURL Builder?

The curl builder works like this: it assembles curl commands from method, headers, body and auth fields, with proper shell quoting and -H flags. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

How to use the cURL Builder

  1. Paste the input (code, data or query).
  2. Run the operation - formatting and validation are instant.
  3. Read any validation message before trusting the output.
  4. Copy the result into your project.

All parsing and transformation happens locally in this tab - your code and data are not sent anywhere.

Frequently asked questions

Windows or Unix quoting?

Unix single-quote style by default; switch to Windows mode for double-quote escaping of inner quotes.

Why does the builder quote my values?

Shell interpretation would otherwise mangle values containing spaces, ampersands or quotes - the emitted command escapes them correctly so copy-paste into any terminal just works.

Does it support request bodies and auth headers?

Yes - JSON or raw bodies become -d flags, and Authorization or custom headers become properly quoted -H flags in the generated command.
