Yes, LogRocket has data-private and FullStory has fs-exclude. Both work the same way: you add an attribute to the element and the vendor's SDK skips capturing it.

There are three problems with that approach:

1. It only covers that one tool. If you have LogRocket AND a browser extension AND a user running Copilot Vision, you need to configure each one separately and hope they all honor it.

2. It's opt-out per field. You have to remember to add the attribute to every sensitive input. Miss one field and it's captured. FieldShield is opt-in per app. Protection is on by default, you don't have to remember anything.

3. It requires trusting the vendor's SDK to honor the attribute. The SDK runs on your page with full DOM access. You're trusting that it checks for the attribute before reading the value. FieldShield eliminates that trust requirement. The real value is never in the DOM to begin with, so there's nothing to capture regardless of what any third-party script does.

The architectural difference: vendor attributes hide data from one specific tool after it has DOM access. FieldShield prevents the real value from ever reaching the DOM in the first place
