Epupp: Live Tamper your Web 作者: PEZ

Epupp has two modes of operation:

1. Live REPL connection from your editor to the web page, letting you inspect and modify the page on the fly, with or without the assistance of an AI agent.
2. Userscripts: Tampermonkey style. Target all websites, or any subset of the web's pages, with prepared scripts that modify or query information from the page. Userscripts can be configured to start before the page loads (document-start), when the DOM is ready but resources are still loading (document-end), or after everything has settled (document-idle).

The two form a powerful pair. The live REPL connection, while happily supporting one-off changes or data extractions, is also a very efficient and fun means to interactively develop userscripts.
