I don't really know what outerframe frame is. I tried to understand from the video and the blog but I'm still not sure what it is. Is it like a web browser but instead of DOM, HTML and JS you have Swift and SwiftUI running in a sandbox?
If so how would that work on non Apple devices? Also how much will that sandbox protect you?
It's purportedly cross-platform. The documentation leaves a lot to be desired, but it is described more here:
https://outerframe.org/ and https://outerloop.sh/native-apps/
Also a blog post about it, with its own video: https://probablymarcus.com/blocks/2026/05/10/like-a-web-view...
It's a fun heretical idea, moving away from a "cross-platform" web to a "multi-platform" web. It's a cross-platform protocol that hands off to platform-specific frontend code. I think it's a natural direction for the web, in a world where LLMs can translate to other platforms.
