I think this would probably be the closest comparison. The password manager model seems like the most realistic way to achieve a good user experience on mobile devices while maintaining strong context and domain validation on desktops. One difference I'm exploring is that Injectless is intentionally declarative and website-based (sites publish what they can inject, rather than the tool heuristically completing everything). I appreciate the perspective.
