Replay

The tool records a deterministic capture of a browser session, logging every DOM change, network request, and state update. From this recording it performs root‑cause analysis and generates a specific fix, which can be delivered to a coding assistant through the Replay MCP integration or shown in plain English via a Chrome extension. By providing the runtime context that agents lack, it eliminates the need for manual debugging in DevTools.

It is aimed at developers who use AI‑based coding agents—such as Cursor, Claude Code, Codex, Copilot, or Windsurf—to troubleshoot front‑end issues. The system is designed for teams that want their agents to understand exactly what happened in the browser when a bug occurs, allowing the agent to propose concrete corrections instead of vague suggestions.

The product runs on macOS, is classified as stable, and integrates with existing development workflows without requiring additional setup beyond installing the MCP component or the Chrome extension. It targets typical UI problems like non‑responsive buttons, broken data imports, sluggish page loads, and flashing content, delivering automated, agent‑assisted fixes.
