Multiplayer is a developer tool that runs locally alongside AI coding agents to automate the debugging loop—detecting, triaging, deduplicating, and fixing bugs across development, testing, QA, and production. Built on OpenTelemetry and available as open source, it captures full-stack, unsampled session data and feeds aggregated failure context to coding agents like Claude Code, Codex, Copilot, and Cursor to produce merge-ready pull requests.
