Source code

The folder DeepBlocker is installed from is its complete source. DeepBlocker's code and uBlock Origin's are plain JavaScript, HTML and CSS, and every WebAssembly module ships with its text-format source (.wat) beside it. Three bundled libraries — CSSTree, HSLuv and js-beautify — are included in the minified form their authors publish; the third-party notices link their source. uBlock Origin's source is published at github.com/gorhill/uBlock.
