We built a framework for executing background scripts and Greasemonkey/Tampermonkey scripts based on the design ideas of Greasemonkey/Tampermonkey. It also has several unique APIs that enable scripts to do more. Furthermore, we provide a fantastic online editor that makes script code development more pleasant and easy.
