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.

Features worth noting:

• Better data for coding agents (and humans): we capture and pre-correlate deep, unsampled data across your entire system, giving your agent the complete runtime picture. Nothing is missing from frontend user actions to backend traces and logs, including request/response content and headers from deep within your system.

• Session-based data collection: Multiplayer listens continuously but only saves data when something goes wrong. Instead of bloated, costly and noisy always-on collection you get all the benefits of a leaner, targeted data model.

• Plug and play with your favorite coding agent: we’re vendor-agnostic by design, it works with Claude Code, Codex, Copilot, Cursor, and whatever ships next.

• Local-first and secure: run Multiplayer right next to your coding agent. We cache sessions locally and send data only when we identify a new issue.

• Intelligent issue triage and deduplication: we filter for high-priority bugs and group identical errors locally. You get one high-quality, merge-ready fix for critical issues, instead of an avalanche of duplicate PRs for the same bug.

Who it's for: For developers who want self-healing systems, not just more alerts and dashboards. If you are already using an AI agent to write your code, Multiplayer gives it the data it needs to fix application bugs in production when they break. You can get started in just a couple of minutes by copy/pasting one command line into your terminal.
