replayio is a Codex plugin that connects the host agent browser to Replay.io's recording and QA tooling. According to plugin.json, it records browser sessions with the Replay Browser (selected via AGENT_BROWSER_EXECUTABLE_PATH), uploads pending recordings automatically when a turn ends, and lets recordings be analyzed through Replay MCP tools or Replay QA. It is also used to create Replay QA projects for recording analysis or live-app exploration. In MCP Apps-aware hosts, tool results can render rich debugging widgets covering logpoints, console output, React trees, Redux state, network requests, screenshots, source code, profiles, and exception stacks. The plugin is authored by Replay, listed under the Developer Tools category with Interactive, Read, and Write capabilities.

Overview

Replay.io provides a session recording engine for time-travel debugging and Replay QA, an AI-driven QA service. Per the replay.io homepage, Replay QA can be pointed at any web app via a URL for a one-time check, or connected to a GitHub repo for continuous testing; it explores the app, writes and runs Playwright tests with Replay recording, and files bug reports with a root cause and suggested fix. The site also describes Replay for CI, which analyzes existing Playwright/Cypress test failures and posts root cause and fix to PRs, and a Replay QA API for embedding QA as a quality gate in other platforms.
