pw-repl

About

pw-repl is a command-line Playwright REPL that connects to a Chromium browser over the Chrome DevTools Protocol, either your existing session or one it launches. You type commands at a prompt, and agents send the same commands with a send subcommand, so every action is visible to both sides. It can snapshot pages, mock or fail backend responses, record user steps for an agent to replay, and record narrated videos, which helps reproduce bugs.
