DevTools Protocol
A debugging interface protocol exposed by Chromium-based browsers. It sends JSON commands over a persistent WebSocket connection to query and control pages, and supports DOM manipulation, network interception, device emulation, and related capabilities.
Timeline (last 90 days)
Playwright was developed by Microsoft and implements browser automation based on the DevTools protocol.
The DevTools protocol implements bidirectional asynchronous communication over sockets, making Playwright faster and natively asynchronous.
The DevTools protocol (Chrome DevTools Protocol) is the debugging interface exposed by Chromium-based browsers, through which developers can establish a persistent WebSocket connection to the browser and send JSON commands to query and control pages.
Playwright abandons the driver layer and goes directly through the DevTools protocol, so it runs right after installation without separately downloading and maintaining drivers.
