The online Faust Editor can be used to edit, compile and run Faust code from any Web Browser with WebAssembly support. It works completely on the client side and it is therefore very convenient for situations with many simultaneous users (workshops, classrooms, etc.). It embeds the Faust compiler with an efficient webassembly backend and offers polyphonic MIDI support.
The editor engine is based on CodeMirror. It provides syntax highlighting, auto completion and direct access to the online documentation. The documentation command (ctrl-d) uses the function name at the cursor position to locate to the relevant information.
The recommended browsers are the latest versions of Firefox and Chrome.

We use Vite for development mode and builds. Dependencies include CodeMirror for providing an editor, FaustWasm for compiling Faust DSP client-side, and FaustUI for rendering GUI widgets.
The gFaustLibSnippets content in the src/codemirror/mode/faust/faustsnippets.js file has to be manually updated with the result of the faust2atomsnippets -s *.lib command done in the Faust libraries folder.
