96.8% of tasks done perfectly. No other tool tops 84%.
A Playwright script survives about as long as the page it was recorded against. Codegen locators capture one DOM snapshot, and a redesign a few months later leaves you patching selectors instead of shipping. Even driven by an agent through Microsoft's own playwright-cli, 29% of those 31 live-site tasks ended short of a perfect score.
In ego lite, your agent reads the page as a compressed Snapshot with stable @N refs and writes the JavaScript itself, so it adapts when the page changes instead of breaking: 96.8% of the same 31 tasks ended perfect, at the fastest average task time of the five tools measured.
