⑤ Click the ScriptCat icon in the upper right corner, click ┆ > Get Scripts in the upper right corner of the interface that appears, and you can go to the script site to search and install scripts.

Note: Extensions installed this way cannot be automatically updated. If you need to update, please repeat the above steps to update the extension (replace files and reload once).

Get Scripts​

In addition to scripts, you can also get some script information and tutorials from Tampermonkey Chinese Forum and Script Development Guide.

ScriptCat Script Site​

ScriptCat Script Site is the script site for this extension, where you can publish scripts you write.

  • New script site
  • Background scripts/scheduled scripts
  • User-friendly interface

Userscript.Zone Search is a new website that allows searching for user scripts by entering appropriate URLs or domains.

  • Large amount of script resources
  • Easy to find suitable user scripts
  • Only shows user scripts from reviewed user script pages or at least pages with comment functionality

GreasyFork​

GreasyFork is a widely used platform for hosting and sharing userscripts, allowing developers to publish and users to install browser-based scripts that enhance or modify website functionality. The site was created by Jason Barnabe and is known for its emphasis on security and open-source transparency, offering a large collection of scripts to improve the browsing experience.

Jason Barnabe is also the original creator of the Stylish browser extension. However, Stylish was sold in 2016 and is now operated by a different company, with no direct involvement from Jason Barnabe in its subsequent development.

GitHub/Gist​

You can search for script resources in Github and Gist.
