What is Multiplayer?

Multiplayer is a local-first debugging tool that connects your coding agent directly to production to automatically fix application bugs. It captures full-stack, auto-correlated, unsampled data—from frontend screens to backend traces and logs—including request/response content and headers that observability tools often miss. The tool runs locally next to your coding agent, caches sessions on your machine, and only sends data when it identifies a new issue. It integrates with popular coding agents like Claude Code, Codex, and Copilot, routing issues directly to them without requiring tool switching or proprietary agents.

Application scenarios

  • Production bug fixing

    Automatically diagnose and fix application bugs in real-time by connecting your coding agent to production systems.

  • Debugging without noise

    Eliminate PR slop and review fatigue by getting only the data you need, with issues deduplicated so the same bug is tracked once.

  • Full-stack debugging

    Access frontend screens, backend traces, logs, and request/response content from all components in your system.

  • Local-first development

    Run Multiplayer locally to debug without sending sensitive code to external servers, caching sessions on your machine.

  • Coding agent integration

    Route production issues directly to Claude Code, Codex, Copilot, or any other coding agent you already use.

  • Observability cost reduction

    Capture a short session of relevant data instead of saving all data "just in case," reducing expensive observability tool costs.

Core Features

  • Full-stack data capture

    Automatically gathers frontend screens, backend traces, logs, and request/response headers from all system components.

  • Intelligent deduplication

    Issues are deduplicated so the same bug is tracked only once, regardless of how many times it was reported.

  • Local-first architecture

    Runs locally next to your coding agent, caching sessions on your machine and sending data only when a new issue is identified.

  • Coding agent integration

    Works with Claude Code, Codex, Copilot, and other agents—no need to switch tools or learn a proprietary agent.

  • One-command setup

    Install and run with a single terminal command: `npm install -g @multiplayer-app/cli && multiplayer`.

  • Selective data sharing

    Complete control over what data you debug—only send the data you want to share.

  • High-quality PR generation

    Produces a handful of high-quality PRs instead of an avalanche of noisy ones.

  • Automatic bug fixing

    Connects your coding agent directly to production to fix application bugs automatically while your system is running.

Target users

Engineering teams from startups to enterprises who need to debug production applications efficiently. Specifically, developers using coding agents like Claude Code, Codex, or Copilot who want to eliminate PR slop and reduce debugging noise. Also useful for teams that currently rely on error monitoring tools (like Sentry Seer) or observability-based AI agents (like Datadog Bits AI) and want a more developer-focused, local-first alternative.

How to use Multiplayer?

Install the CLI globally with npm install -g @multiplayer-app/cli, then run multiplayer in your terminal. The tool runs locally next to your coding agent, automatically capturing production data and routing issues to your preferred coding agent (Claude Code, Codex, Copilot, etc.). You get complete control over what data is sent—only data for new issues is shared.

Effect review

Multiplayer addresses a real pain point for engineering teams: the noise and inefficiency of debugging production bugs with existing tools. By connecting coding agents directly to production and deduplicating issues, it promises to reduce PR slop and review fatigue significantly. The local-first architecture is a strong security feature, keeping code safe while still enabling automatic bug fixes. For teams already using Claude Code or similar agents, this tool could streamline debugging without requiring a new workflow. However, its effectiveness ultimately depends on how well it integrates with your specific stack and coding agent.

Frequently Asked Questions
