Could you build this?

Partial Embedding an agent widget via a script tag is easy, but reliable automated browser interaction and DOM state synthesis across arbitrary third-party web apps require sophisticated agentic vision and DOM reasoning infrastructure.

What it would actually take: A full version requires an embedded iframe/shadow-DOM script coupled with a client-side agent runner or cloud-orchestrated headless browser sessions (e.g. Playwright). The difficult part is reliable DOM change observation, intent-to-action parsing, and handling diverse SPA state models, requiring expertise in browser extension/automation internals and agent evaluation pipelines.

Discussion

5 comments analyzed.

Competitors mentioned: Rover, PageAgent, Browser-Use

Concerns raised: PageAgent's DOM understanding is too simplistic, struggles with shadow DOMs and iframes, PageAgent is slow and inaccurate, PageAgent requires many steps (30+) for basic tasks, Element marking approach (CUA style) unclear in actual model calls

Feature requests: Cross-origin request support for cross-site interactions, Seamless handling of different page frameworks, iframes, and shadow DOMs
