Browser-Based Applications Experimental

Run MNE-CPP applications directly in your web browser using WebAssembly — no installation required. This feature is experimental and under active development. The Wasm module is downloaded once and executed entirely inside your browser's sandboxed runtime.

Privacy. No files are uploaded to any cloud service or remote server. All computation happens locally on your machine; your data never leaves your device.
