This tool uses experimental WebUSB technology. Please use it at your own risk, this tool is written to be fully local and doesn't share user data with cloud. This is based on port of webadb/webadb.js and I have verified the code to not do anything notorious.

To understand the general risk of using WebUSB on untrusted websites - read this article. I am working on a tool that can do GC analysis as a standalone tool without WebUsb.
