Interesting approach building a dedicated browser for AI agents. The browser-as-infrastructure angle makes sense — most MCP browser servers just wrap Chrome with CDP, which adds significant overhead.

One thing I've been thinking about is whether we even need a separate browser process. On macOS, Safari's AppleScript bridge lets you run JS in any tab without launching anything new. Your existing browser with all its sessions is already there.

The trade-off is obvious though: a purpose-built browser like Vessel can add agent-specific features (structured DOM output, action recording) that you'd never get from a general-purpose browser's scripting API.

How are you handling authenticated sessions? That's been the biggest pain point I've seen with headless/separate browser approaches — users have to re-login or copy cookies.
