cURL Command Builder FAQ

            

            

                

                    Is the cURL builder free to use?
                    
Yes. The cURL builder and the code export are free with no signup. Everything is generated locally in your browser.

                

                

                    Which programming languages can I export request code to?
                    
You can export Python with requests, JavaScript with fetch, Java with HttpClient, Go with net/http, Rust with reqwest, and C# with HttpClient.

                

                

                    Is my request data uploaded to a server?
                    
No. The command and every code example are generated with JavaScript inside your browser, so URLs, headers and request bodies never leave your device.

                

                

                    What is the difference between Form data and JSON data?
                    
Form data sends key equals value pairs URL encoded with --data-urlencode, which is what HTML forms submit. JSON data sends a raw JSON string with -d, usually paired with a Content-Type: application/json header. Raw data passes your input through unchanged.

                

                

                    How do I add a proxy to the generated command?
                    
Choose HTTP proxy or SOCKS5 proxy, then enter the host, port and optional credentials. The cURL command uses the -x flag, and each language example applies the proxy through its own standard mechanism.

                

                

                    What dependencies do the generated examples need?
                    
Python examples use the requests library and Rust examples use reqwest with the blocking feature. JavaScript, Java on JDK 11 or newer, Go and C# use only standard libraries.

                

                

                    Does the file upload option upload my file?
                    
No. You type a local file path and it is written into the command as text. The file itself is never read or uploaded, because the whole tool runs in your browser.
