Officially tested and tagged. Recommended for production use and reproducible research.

Development Builds

Automated nightly builds from the staging branch. Latest features and fixes; may be less stable.

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.

Stable builds are published from tagged releases. Nightly builds are published from the current staging branch to the/dev/ subdirectory.

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.
