Overview

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.
