About Multiplayer

Multiplayer is a debugging agent that connects your existing coding agent to production so bugs get fixed against real data rather than against a guess. The problem it names is specific and current: coding agents produce plausible fixes when they cannot see what actually happened, and the result is PR slop — changes that look reasonable, pass review, and do not address the fault. Multiplayer's answer is better data. It captures full-stack, auto-correlated, unsampled telemetry spanning frontend screens through backend traces and logs, including the things conventional observability tools discard — request and response bodies and headers from every component in the system. That gives the agent the actual failing request rather than an aggregate metric. Installation is one copy-paste in the terminal via a global npm package, and it runs locally, which matters because local operation is what lets it eliminate PR slop before a pull request exists rather than reviewing one afterwards. The published use cases cover debugging AI-generated code, feature development, multi-agent development workflows, failing tests and mobile development. The free tier is unusually generous — unlimited bug fixes forever with full control — and the paid tier at $12 per user adds SSO/SAML and 30-day data retention.

Key Features

✓Connects your existing coding agent to production data

✓Full-stack, auto-correlated, unsampled telemetry

✓Captures request/response content and headers other observability tools drop

✓Runs locally via a one-line npm install

✓Frontend screens through backend traces and logs in one correlated view

Multiplayer Pros & Cons

✅ Pros

+Unsampled request/response capture is exactly the data agents lack when guessing at a fix
+Free tier with unlimited bug fixes is genuinely usable rather than a trial
+$12 per user is far below typical observability seat pricing
+Local operation means production data does not have to leave your control to use it
+Agent-agnostic — it improves whichever coding agent you already run

⚠️ Cons

−Capturing unsampled request and response bodies raises real data-handling questions
−30-day retention is short for intermittent bugs that surface quarterly
−Value depends on already using a coding agent for fixes
−Full-stack instrumentation is more setup than the one-line install implies for complex systems
