Projects Using Peggy

This is a list of known projects built using PEG.js. Feel free to extend it if you know about more (just keep the list sorted alphabetically).

This page will be updated as projects start to use Peggy instead of PEG.js, but this information is still useful for folks to find examples.

See also the list of npm packages dependent on pegjs.
