Chisel is a creation of Xfive, a web development studio specializing in modern WordPress development.
At Xfive we love WordPress but we think that WordPress development could be a slightly more pleasant experience. That’s why we are fans of Timber library.
A few years ago we created Chisel, a tool for creating and developing WordPress themes based on Timber.
The latest version of Chisel was completely rewritten to Webpack and adds a bunch of new features, including support for static websites.
If you are looking for documentation of the previous, Gulp based, version, it’s here.
