About cURL Builder
The cURL Builder helps you assemble a correct cURL command without memorizing its flags. Fill in the URL, pick a method, add headers (one per line), a body, and basic auth — and get a tidy multi-line cURL command ready to run in a terminal.
Useful for testing APIs, writing docs, or producing example commands. All in the browser.
FAQ
Are any network requests sent?
No. This tool only transforms/analyzes text in your browser — no actual HTTP request is sent, and your data never leaves your device. (Tools that truly call an external server are intentionally not provided due to browser CORS limits.)
Is my data safe?
Yes. All processing happens entirely locally in your browser. Nothing is uploaded, logged, or stored on our servers.
