Starting in April 2021, Peggy has been maintained by Joe Hildebrand (@hildjj). It was previously known as PEG.js, but had fallen into limbo before a community-desired fork.

Since its inception in 2010, PEG.js was maintained by David Majda (@dmajda), until May 2017 when Futago-za Ryuu took over.

You are welcome to contribute code. Unless your contribution is really trivial you should get in touch with us first — this can prevent wasted effort on both sides.

Note that Peggy is still very much work in progress. There are no compatibility guarantees until version 2.0 (we needed to do a major version release at 1.0 to take over the Peggy name).
