A FastAPI service manages browser tasks. LangGraph retains the request, page observations, action history, and human decisions as the planner moves between steps. Pausing for approval or manual input preserves the same task so it can resume afterwards. Playwright sends structured actions through a relay to the browser extension. The extension uses the Chrome DevTools Protocol to read and control the dedicated tab, then returns the resulting page state to the cloud agent. The operator’s machine needs the extension, with the automation service and reasoning hosted centrally.
