Multiplayer runs locally alongside tools like Claude Code, Codex, and Copilot. From there, it feeds your agent the full-stack, pre-correlated, and unsampled data and context observability tools miss. Operating with a secure, local-first approach, we intelligently deduplicate issues to eliminate review fatigue. Multiplayer replaces log grepping and "PR slop" with a handful of high-quality, automated pull requests.
What to expect from an ideal product
- Records your entire application stack in one session, so you can see exactly what users clicked while watching backend API calls happen in real-time
- Automatically links frontend user actions to their corresponding backend traces and database queries, eliminating the guesswork when debugging issues
- Captures complete request and response data including headers and payloads, giving you the full picture of what data flows between your frontend and backend
- Correlates user interface interactions with server-side performance metrics and logs, making it easy to spot where slowdowns or errors actually originate
- Provides a unified timeline view where you can scrub through frontend screenshots while simultaneously seeing which backend services were called at each moment
