Build an HTTP request and generate the code

It happens all the time: you test an HTTP request in one language and then need it in another. Rewriting the code by hand, fiddling with headers and body, is a bore. Here you build the request just once and get the equivalent snippet in several languages.

Define the URL, the method, the headers and the body. The code comes out ready in cURL, JavaScript fetch, axios, Python requests and Go net/http. It's the shortcut for taking an API call out of a testing tool and dropping it straight into your code, already in your project's language.

Since everything is generated in the browser, the request's data never leaves your device. That makes it safe to build calls carrying tokens or sensitive information.

Frequently asked questions

Which languages does the page generate?

Three: cURL, JavaScript fetch and Python requests. Each one sits in its own text box, filled in and rebuilt on every keystroke in the fields above. There is no axios, Go, PHP or Java output, and no copy button either — the text is selectable, so click inside a box, select all and copy by hand. The method dropdown covers GET, POST, PUT, PATCH and DELETE.

I typed a header and it never showed up in the code. Why?

Headers get read one per line, split at the first colon, so any line without a colon gets dropped silently. Write Authorization: Bearer xxx on one line and Content-Type: application/json on the next. Worth noting that no header is ever added on your behalf: if the body carries JSON, the Content-Type has to be spelled out there, otherwise the API on the other end answers with an error.

Does the tool actually fire the request?

No. It only writes the code; no call leaves the browser and there is no response panel, status code or timing. The body gets copied as plain text into all three snippets — it becomes the -d in cURL, the body in fetch and the data= in requests, with no JSON validation and no formatting. Since nothing gets sent or stored, building a call that carries a production token is safe, and the real test happens in your terminal.
