Does this tool send my curl command anywhere?

No. Parsing and code generation both happen in your browser with JavaScript. The command, headers, and any tokens inside it are never uploaded to a server.

Which curl flags are supported?

-X/--request, -H/--header, -d/--data/--data-raw/--data-binary, -F/--form, -u/--user, -b/--cookie, -A/--user-agent, -e/--referer, -G/--get, and -k/--insecure. Common no-op flags like --compressed, -s, -v, and -L are ignored since reqwest handles equivalents by default.

Why does the generated code set Content-Type itself?

curl sends a default Content-Type for -d bodies even though it is not written on the command line. When the body looks like JSON, the tool adds a Content-Type: application/json header; for a plain -d body it adds application/x-www-form-urlencoded, matching curl's real behavior.

What happens with -F form fields?

Each -F field is added to a reqwest::multipart::Form. A value starting with @ is treated as a file path and attached with form.file(), matching how curl uploads files; other values are added with form.text().

What crate does the generated code depend on?

reqwest with the json feature (plus multipart when the curl command has -F fields), and tokio with the full feature for the async runtime. Both are listed as comments at the top of the generated code.

Does -b or a Cookie header produce a real Cookie header in the Rust code?

Yes. Both -b and an -H "Cookie: ..." header are parsed into name/value pairs and re-joined into a single Cookie header on the request, instead of being dropped.

curl Command

Rust (reqwest)

Summary

Paste a curl command and get equivalent Rust code using the reqwest crate, with headers, JSON body, cookies, and auth already translated.

How it works

Paste a curl command, including one copied from a browser devtools network tab.
The parser tokenizes the command, honoring quotes and backslash line continuations.
Flags such as -X, -H, -d, -b, -u, -F, and -G are mapped to their reqwest equivalents.
A JSON body is detected automatically and sent with a Content-Type header set for you.
The generated Rust program appears in the output box, ready to paste into main.rs.

Use cases

Turn a "Copy as cURL" request from browser devtools into a Rust test program.
Reproduce an API call from documentation or a support ticket in Rust.
Convert a curl example from a README into a starting point for a reqwest client.
Debug an API integration by replaying the exact request curl sent, in Rust.
Translate a webhook test command into a repeatable Rust program.
Build a quick async reqwest client around a request captured from a mobile app proxy.
