What is Debugging Agent for Developers?
Multiplayer is a debugging agent for developers that connects your favorite coding agent (like Claude Code, Codex, or Copilot) directly to production to fix application bugs automatically. It runs securely and locally alongside coding agents, capturing full-stack, auto-correlated, unsampled data that observability tools miss—including request/response content and headers from all system components.
The tool manages the entire debugging process from bug identification to fix: data gathering, intelligent triage and issue deduplication, coding agent prompting, PR creation, and user notification. It replaces log grepping and
Debugging Agent for Developers pricing
Pricing model: Freemium
Multiplayer offers three plans: (1) Open Source: $0 forever with full control, unlimited bug fixes, and community support (coming May 2026); (2) Hosted: $12/user with unlimited bug fixes, SSO/SAML, 30-day data retention, and email support (free trial available); (3) Enterprise: Custom fixed monthly pricing with unlimited bug fixes, custom data retention, and priority support SLAs. There is also a free 7-day trial available at go.multiplayer.app.

Frequently asked questions about Debugging Agent for Developers
What is Multiplayer?
Multiplayer is the debugging agent for developers that connects your favorite coding agent directly to production to fix application bugs automatically. It runs securely and locally alongside tools like Claude Code, Codex, and Copilot, feeding your agent full-stack, auto-correlated, unsampled data that observability tools miss.
How do I get started with Multiplayer?
You can get started in just a couple of minutes by copy/pasting one command into your terminal: npm install -g @multiplayer-app/cli && multiplayer. Most teams are fully configured in just a few hours and can get started the same day.
What coding agents work with Multiplayer?
Multiplayer works with Claude Code, Codex, Copilot, and any other coding agent you already use and love. You can route issues directly to all coding agents without tool switching or ramping up on a proprietary agent.
How does Multiplayer handle data security?
Multiplayer is local-first and more secure. It runs locally next to your coding agent, caches sessions locally, and sends data only when a new issue is identified. Unlike other debugging agents, Multiplayer doesn't need access to your code.
What is PR slop and how does Multiplayer fix it?
PR slop refers to the avalanche of noisy, low-quality pull requests from observability and error management tools that lack real runtime context. Multiplayer eliminates this through intelligent issue deduplication and by capturing only the data needed to fix issues, resulting in a handful of high-quality, merge-ready PRs instead.
What languages and platforms does Multiplayer support?
Multiplayer supports any language including JavaScript, Node.js, Python, Java, .NET, Go, Ruby (and more to come). It works in any environment (production, staging, development), any architecture (on-prem, cloud native, serverless, hybrid), and any platform including web and mobile applications like React Native.
How is Multiplayer different from Sentry or Datadog?
Sentry Seer works well for error logging but produces PR slop with sampled/missing data. Datadog Bits AI is an SRE agent for DevOps, not developers. Multiplayer captures a short time window of unsampled data around an issue with full request/response content and headers, giving developers the exact data needed to fix application bugs.
What is the free trial for Multiplayer?
Multiplayer offers a free 7-day trial at go.multiplayer.app where you can test the hosted plan with unlimited bug fixes before committing to a paid subscription.
How does Multiplayer deduplicate issues?
Multiplayer intelligently deduplicates issues by filtering for high-priority bugs and grouping identical errors locally. The same bug is tracked only once regardless of how many times it is reported, so you never have to review or fix the same issue twice.
Can I use Multiplayer for mobile app debugging?
Yes, Multiplayer provides full-stack debugging for mobile apps, especially React Native. It captures complete correlated sessions from gestures and navigation events to backend traces, logs, and API calls, allowing you to replay issues visually and see exactly what the user did and how your system responded.
