curlconverter is a browser-based tool and JavaScript library that transforms curl commands into equivalent source code across more than 30 programming languages and HTTP client libraries. It parses curl command arguments into an abstract syntax tree and generates idiomatic code by applying per-language templates, making it a curl command transpiler rather than a simple converter.
The tool operates entirely client-side without any server round-trips, ensuring all conversion happens privately in the browser without transmitting data externally. It can also function as a drop-in curl replacement that prints generated code instead of executing the HTTP request, and integrates with VS Code as a right-click context menu extension for pasting and converting curl commands directly in the editor.
Alongside the generated code, the conversion pipeline produces a list of warnings flagging unsupported or ambiguous curl options. The project is available as a JavaScript library accepting curl command strings or argument arrays, and as a web interface that captures network requests from browser developer tools for conversion.
