Already have observability?
Here's what you're still missing.
Multiplayer’s full stack session recordings help you resolve technical issues and complex bugs in minutes instead of hours.
How is Multiplayer different?
Purpose-built for debugging, not monitoring
While APM tools excel at monitoring system health, Multiplayer is laser-focused on shortening your debugging workflows and resolving the technical issues that slow your team down.
• APM tools are broad monitoring platforms designed to track system performance and health across infrastructure. Valuable for Ops teams watching dashboards, but requiring developers to manually correlate logs, traces, and metrics across multiple tools when an actual bug needs fixing.
• Multiplayer is designed for debugging and support workflows. We give developers complete context to understand and fix bugs immediately, support teams technical visibility into issues, and end-users an effortless way to report problems.
Transform your debugging workflows: from slow, painful serial hand-offs, to parallel collaboration with end-to-end visibility from the start.
Session-based, full stack correlation
Multiplayer captures complete, correlated recordings of individual user sessions rather than collecting system-wide telemetry, giving you precisely the data you need to debug, without the noise.
• APM tools generate massive volumes of raw telemetry across your entire system, forcing developers to manually correlate disconnected logs, traces, and metrics across multiple dashboards. All the while staying within cardinality limits that often exclude the specific data needed to resolve an issue, and forcing context-switching to other tools to piece together the full picture.
• Multiplayer automatically captures and correlates full-stack context for each session. From DOM events and network requests to backend traces and logs, all in a single, annotatable workspace. Including critical details APM tools miss like request/response content and headers from deep within your system.
Instead of searching for needles in haystacks of system-wide data, you get a complete, ready-to-use recording of exactly what happened during the session where the bug occurred.
Developer-friendly and AI-native
Multiplayer is built for developers who need flexibility and speed, integrating seamlessly with your existing stack.
• APM tools are designed for DevOps and platform teams, often creating vendor lock-in through proprietary agents and data formats. While some APM tools offer session replay features, achieving Multiplayer’s end-to-end visibility requires manual instrumentation and third-party integrations. MCP servers and AI agents are also optimized for interrogating telemetry data, returning incomplete or inaccurate suggestions when debugging because of sampled or fragmented context.
• Multiplayer is built for support and engineering teams. It works with any observability platform, language, framework, or architecture. Cloud-hosted or self-hosted. Accessible from any IDE or AI tool. Every session is a self-contained, complete unit of data: frontend screens, unsampled backend traces, request/response payloads, and team annotations all in one place, giving AI everything it needs to generate accurate insights and fix suggestions.
Multiplayer provides AI tools with the complete, structured context they need to actually help you debug deep technical issues.
Why use Multiplayer?
Better data for AI agents (and humans)
Full-stack, auto-correlated, unsampled. Everything you need from frontend screens to backend traces and logs. We also include things your observability tools miss like request/response content and headers from all components in your system.
Plug & Play with your favorite coding agent
Claude Code, Codex, Copilot, … Route issues directly to any and all coding agents you already use and love. No tool switching or ramping up on a proprietary coding agent. Connect our debugging agent to prod and auto-fix bugs while your system is running.
Local first, more secure
Run Multiplayer right next to your coding agent. We cache sessions locally and send data only when we identify a new issue.Complete control over what you debug. Your code is safe: unlike other debugging agents we don’t need access to it.
Intelligent issue creation and deduplication
No PR slop or review fatigue. We gather only the data you need and just enough of it. Issues are deduplicated so the same bug is only tracked once, no matter how many times it was reported. You never have to review or fix the same issue twice.Getting started with Multiplayer
is easy.
One copy/paste in your terminal, and you’re done.
npm install -g @multiplayer-app/cli && multiplayerMore languages and CLI SDKs can be found in our documentation.
Your coding agent is only as good as
the data it uses. Give it what it needs.
