curl Command Builder
Build a ready-to-run curl command from a method, URL, headers and body — runs 100% in your browser, nothing is uploaded.
curl -X GET 'https://api.example.com/users' -H 'Content-Type: application/json'
🔒 The command is built in your browser — nothing is uploaded.
What this tool does
The curl Command Builder turns the pieces of an HTTP request into a copy-paste-ready curl command. Pick a method such as GET or POST, enter the request URL, list your headers one per line as Key: Value, and optionally add a request body. The command updates live below and includes -X for the method, a -H flag for every header, and --data when a body is present. Every value is wrapped in single quotes and any embedded quotes are escaped, so the output pastes safely into a terminal exactly as shown.
How to use it
Choose the HTTP method from the dropdown, then paste the full URL you want to call. Add each header on its own line, for example Content-Type: application/json or Authorization: Bearer TOKEN. If you are sending data, type or paste it into the body field — JSON, form text, or anything else. Watch the curl command build in real time, then press Copy and run it in your terminal, drop it into a script, or share it with a teammate.
Frequently asked questions
How are quotes and special characters handled?
Each URL, header and body value is wrapped in single quotes, and any single quote inside a value is safely escaped using the POSIX '\'' sequence. This means the command pastes into a shell exactly as written, even when values contain spaces, ampersands or JSON.
Why does GET still show -X GET?
The builder always writes the method explicitly with -X so the command is unambiguous and easy to edit. curl treats GET as the default, so -X GET behaves the same as leaving it out — you can delete it if you prefer the shorter form.
Is my URL, headers or body uploaded anywhere?
No. The curl command is assembled entirely in your browser with JavaScript. Your URL, headers, tokens and body are never sent, stored or uploaded to any server.
