Could you build this?
No Rewriting a browser automation framework like Playwright in Rust to control browser engines (Chromium/CDP, Firefox, WebKit) without node subprocess overhead requires deep systems programming, browser internal protocol knowledge, and asynchronous networking.
What it would actually take: This demands implementing a complete, highly concurrent Rust client for the Chrome DevTools Protocol (CDP) and WebDriver BiDi, handling low-level WebSocket multiplexing, memory-safe frame/page state machines, and DOM tree synchronization. It also requires reimplementing complex Playwright features like auto-waiting, synthetic input event generation, isolated world script injection, and cross-browser protocol shims. The core challenge is the sheer surface area of CDP and ensuring binary-level compatibility and rock-solid event timing across different browser release versions.
