Replay — local, DOM-based browser session replay for agent-driven coding sessions. It captures the browser session your coding agent drives to reproduce or verify a bug, auto-cuts the dead air where the agent thinks, and returns a shareable replay link plus a portable .replay artifact. Built with GPT-5.6 Terra at OpenAI Build Week (https://openai.devpost.com/). This is a single-page application and needs JavaScript enabled to render the full experience.
