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?

Understand unclear, hard-to-describe issues

Users often report confusing behavior or ask questions that require technical clarity. Sometimes the tickets themselves are ambiguous or incomplete. Multiplayer shows exactly what happened on the user's end, so support teams can answer quickly and confidently. No need to ask users for “more info” or escalate unnecessarily.

Resolve complex technical issues or bugs dramatically faster

With full stack session recordings, Multiplayer lets you instantly see how bugs happened in a single timeline, automatically correlating data across all layers of your stack. It reduces guesswork , shortens investigation time, and saves hours from grepping through log files or jumping between dashboards and screens.

Eliminate costly, repetitive escalations

Multiplayer removes the back-and-forth that slows support and debugging workflows down. Support can review a user’s full session, annotate it, and escalate with complete context, so engineering can diagnose issues without reconstructing missing data. Cut down on meeting loops, duplicate work, and miscommunication, and get users to a resolution faster.

Core differences

	APM / Observability Tools	Multiplayer
PRIMARY USE CASE	Monitoring and performance at scale	Deep, collaborative investigation of technical support issues, bugs and escalations
USERS	DevOps, Platform Engineering	Customer Support, Developers, QAs, end-users and external partners
SESSION REPLAYS	Bolt-on feature, not core capability When available, designed primarily for identifying performance bottlenecks and user behavior patterns at scale with restricted control over what gets captured	Versatile by design and developer-friendly Multiple recording modes, install options, and supported use cases. Compatible with any observability platform, language, environment, architecture, AI tool and deployment
DATA PER SESSION	Limited Heavy sampling, limited correlation with frontend events and user feedback, and no automatic capture of technical details like request/response content and headers	Full stack data and complete context Including data like user feedback, request/response content and headers for components deep in your system, team annotations, etc.
TEAM COLLABORATION	Dashboard and alert sharing Teams independently investigate telemetry data and communicate findings externally	View, share, and annotate every aspect of a session recording Teams work directly within the session recording itself, which is also compatible with any existing ticketing system (e.g. Zendesk, Intercom, Jira)
AI CAPABILITIES	Optimized for interrogating telemetry data	Optimized for debugging The MCP server feeds complete, correlated and enriched context to your IDE or AI tool of choice about specific bugs and technical issues
