An experimental port of the Vim text editor compiled to WebAssembly using Emscripten, running in the browser via a Web Worker with SharedArrayBuffer. It supports most Vim features including syntax highlighting, Vim script, and persistent config storage in Indexed DB.
Use cases
- run vim in the browser
- try vim without installing it
- edit files in a web browser with vim keybindings
- demo vim to others via a link
- use vimscript in the browser
- practice vim with vimtutor online
When to choose
- you want to use or demo real Vim inside a desktop browser
- you need a zero-install Vim environment with persistent ~/.vim storage
- you're experimenting with WebAssembly ports of C applications
When to avoid
- you need a stable, bug-free editor for real work - the project is explicitly experimental and buggy
- you're on mobile or a browser without SharedArrayBuffer support
- you need to edit files on a local filesystem or run external tools
