Offline, privacy-first grammar checker. Fast, open-source, Rust-powered - Automattic/harper
Summary

Automattic released Harper, an open-source English grammar checker that runs entirely locally in milliseconds with a memory footprint under 1/50th of LanguageTool's. It avoids sending data to external servers, addressing privacy concerns with Grammarly, and is small enough to load via WebAssembly. Harper currently supports editors like VS Code, Neovim, Helix, Emacs, and Zed through harper-ls.
