Debug platform issues in minutes,
not hours.
Capture everything you need to resolve a bug—from frontend screens, backend traces, metrics, logs and full request/response content and headers. No more digging through APM data.
“This is the fastest way I’ve ever seen to answer the question 'What’s in our backend?’”
Built to eliminate the time sinks of modern engineering
Problem
- Painful bug reproduction with incomplete reports and missing context
- Fragmented debugging stacks with screen replays in one tool, traces in another, and architecture diagrams somewhere elsewhere
- Wasted time sifting through walls of irrelevant logs and metrics
- Uncontrolled costs from APM and observability platforms
- Slow and siloed cross-team escalations and poor collaboration
- Outdated or missing documentation
Solution
- Capture frontend screens, backend traces, metrics, logs, and full request/response content and headers—all in one unified session
- Get real-time, auto-documented visibility into your logical architecture, components, APIs, dependencies, environments, and data flows
- Debug faster in a single unified environment. No more context switching and scattered tools
- Streamline cross-team collaboration with shared debugging sessions
- Let users report bugs with a single click
- Replaces screen recording tools and grepping through log files

Why choose the Multiplayer Platform Debugger?
Fix bugs faster
Engineers isolate root causes in minutes by replaying full-stack sessions: frontend interactions, backend logic, and infrastructure metrics in one timeline. No need to guess or hunt through dashboards. It's all there, instantly.
Improve user experience
Let users report bugs with one click—complete with context. No vague tickets, screenshots, or back-and-forth. Just a link to the exact session, so engineers can fix the issue quickly and close support tickets faster.
Gain backend clarity
Turn your backend from a black box into an open book. Real-time, auto-documented platform documents and diagrams allow your team to understand the system, not just respond to incidents.
Improve developer experience
Instead of jumping between frontend tools, APM dashboards, log aggregators, and architecture diagrams, you get one unified view. Debugging goes from painful context switching to focused problem solving.
Catch issues before customers do
Use deep session replays during staging, QA, and dev—not just in production. Spot issues before users do and reduce the number of customer-reported issues.
Streamline team collaboration
Share session replays with a single link. Everyone, from engineers to SREs to support, gets the same full-context view. Instant alignment on context—reducing escalations and cutting resolution time in half.
De-risk legacy systems
Multiplayer helps you observe and understand undocumented, aging systems, so you can modernize confidently without starting from scratch.
Prevent technical debt
When you can see exactly how your systems behave in real time, you make smarter, well-informed architectural decisions. No patchwork fixes. No mysterious side effects.
