Could you build this?
Partial The dashboard and orchestration of browser agents are vibe-codeable with Playwright and LLMs, but running many reliable agent swarms against real products is infrastructure-heavy and hard to get right.
What it would actually take: The stack is headless browser fleets (Playwright or similar) driven by LLM agents, with a planner that derives test flows from specs, repos, and analytics, plus video and log capture. Hard parts are scaling parallel sandboxed browsers, reducing flakiness, and integrating with product sources. This needs distributed-systems and test-automation experience.
