The xmlq website operates entirely client-side, leveraging WebAssembly (WASM) to run the Go-based xmlq library directly in the browser. This approach ensures that all XML processing, including parsing, masking, and formatting, occurs locally on the user's device without any server-side dependencies. By compiling the xmlq library to WASM, the site delivers fast, secure, and private XML manipulation, as no data is sent to a server. Users can input XML, configure masking options, and view the masked output instantly, making it ideal for sensitive data handling and seamless deployment on static hosting platforms like GitHub Pages.
