Auto-document your entire software platform
Automatically discover, track and document your services, dependencies, and APIs. Available on the Enterprise plan.
“This is the fastest way I’ve ever seen to answer the question 'What’s in our backend?’”
A live map of your system. Always up-to-date, never manually maintained.
Problem
- Static, outdated diagrams and docs
- Manual documentation overhead that steals engineering time
- Effort-intensive debugging due to lack of visibility
- Siloed and fragmented knowledge across distributed teams
- Fragmented workflows and context switching across diagrams, logs, and tickets
Solution
- Capture and update everything automatically: logical architecture, components, APIs, dependencies, and environments
- Full stack session recordings come with integrated service maps, letting you trace the exact path of a request or error across the system in real time
- A single source of truth for cross-team collaboration and alignment: no more scattered information across wikis, whiteboards, and Slack
Turn your backend from a black box into an open book
Click through the steps to see how it works:
Capture sessions
Multiplayer runs locally next to your favorite coding agent and surfaces new issues automatically, saving unsampled, full-stack session data for each bug. Your coding agent automatically receives exactly what it needs to fix the bug, deduplicated, pre-correlated.

Why choose the Multiplayer system dashboard?
Instant system visibility
See your entire distributed system (components, APIs, dependencies, and environments) automatically and in real-time. From the high-level architecture to request/response content and headers.
Better debugging
Eliminate blind spots and identify root causes faster by immediately understanding service interactions and data flows across your system. No more juggling tabs or grepping through log files.
Boost team productivity
No more hand-drawn diagrams or stale wiki pages. Multiplayer auto-generates an accurate system overview and keeps it up to date, saving hours of dev time and endless sync meetings.
Accelerate onboarding
New engineers ramp up 10x faster with an always-accurate overview of all facets of your system. Eliminate long onboarding sessions, team overhead, and the pain of digging through outdated docs.
Prevent technical debt
Make decisions based on runtime, unsampled, full-stack session data. You have complete context of how the system actually behaves, reducing the risk of rework, unnecessary complexity, and long-term inefficiencies.
Untangle legacy systems
Auto-document hard-to-understand systems so your team can safely modernize, refactor, or sunset services, without relying on tribal knowledge.
Strengthen platform security
Visualize real service interactions and traffic paths to spot unmonitored endpoints, insecure flows, and hidden dependencies before they turn into vulnerabilities.
Get a handle on SaaS sprawl
Maintain a live catalog of all your internal and external services, APIs, and dependencies. Know what’s in use, what it connects to, and where it lives.
Preserve institutional knowledge
Your system’s design decisions, architecture history, and rarely-touched service dependencies stay captured, surviving reorgs, onboarding, and inevitable team changes.Getting started with Multiplayer

Debugging agent for developers
The Multiplayer debugging agent connects your favorite coding agent to prod to fix application bugs automatically. It manages the whole process from bug identified to bug fixed: data gathering, intelligent triage and issue deduplication, coding agent prompting, PR creation and user notification.Try it nowpairs with
