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 net/http handles equivalents by default.

Why does the generated code set Content-Type itself?

Unlike some HTTP libraries, Go's net/http does not guess a request body's content type for you. 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 what curl sends by default.

What happens with -F form fields?

Each -F field is written with a mime/multipart Writer. A value starting with @ is treated as a file path and read with os.Open, matching how curl uploads files; other values are written as plain form fields.

What if my curl command spans multiple lines?

Backslash line continuations, the format most terminals and browser "Copy as cURL" buttons produce, are joined automatically before parsing.

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

Yes. Both -b and an -H "Cookie: ..." header are parsed into name/value pairs and attached with req.AddCookie(), instead of being left as a raw header string.

Paste a curl command and get equivalent Go code using net/http, with headers, JSON body, cookies, and auth already translated.

curl Command

Go (net/http)

Summary

Paste a curl command and get equivalent Go code using net/http, 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 net/http equivalents.
A JSON body is detected automatically and sent with a Content-Type header set for you.
The generated Go program appears in the output box, ready to copy into a main.go file.

Use cases

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