While that's all well and good. The problem is a website can update it's code every time you load it. So while the user can audit nothing is being sent, they would have to do this every time they load it.

While I think the UI is super nice here. I'd personally stick to a trusted tool from an org and project with a good reputation and long history.

Could we automate the auditing of the website every time it runs?

working on ideas to do this, currently i have this but not good enough yet https://secvant.com/changelog

agreed, i'll see if there's a good way for me to prove when and what changed maybe be uploading to github and keeping it open source
