cURL to Java

Summary

Paste a curl command and get equivalent Java code using java.net.http.HttpClient, with headers, JSON body, cookies, and basic auth already translated.

How it works

1. Paste a curl command, including one copied from a browser devtools network tab.
2. The parser tokenizes the command, honoring quotes and backslash line continuations.
3. Flags such as -X, -H, -d, -b, -u, -F, -G, and -k are mapped to HttpClient builder calls.
4. A JSON or form body is set with HttpRequest.BodyPublishers, adding a default Content-Type when curl would have.
5. The generated Java class appears in the output box, ready to copy into a project and run.

Use cases

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