All-in-one tool for system design
The only tool your team needs to collaboratively design, evolve, and iterate on your distributed system architecture.
“We used to have a quarterly meeting where we’d all fly in, unfurl a giant poster and add post-it notes with our bits of the software architecture. It was obsolete the moment someone shipped a new feature. Now, we have real-time visibility, full accountability, and an easier way to collaborate."
You've got better things to do than manually update diagrams and docs
Problem
- Static, outdated diagrams and docs
- Time wasted on manual updates
- Teams jump straight into implementation without clear alignment on architecture or tradeoffs
- Effort-intensive debugging due to lack of visibility
- Siloed and fragmented knowledge across distributed teams
- Context switching chaos when looking for information
Solution
- Always up-to-date, interactive diagrams and docs
- Capture everything automatically: logical architecture, components, APIs, dependencies, environments, and data flows
- Design collaboratively and catch issues early, before they turn into technical debt
- Effortless debugging based on real-time system visibility
- A single source of truth for cross-team collaboration and alignment: no more scattered information across wikis, whiteboards, and Slack

Click through the steps to see how it works:
Auto-generated architecture diagrams
Automatically populate architecture diagrams using your telemetry data. No manual effort required to get an accurate and always-up-to-date view of your system, from the high level, logical design to the individual components, APIs, integrations, and dependencies.
Effortless architecture visualizations
Architecture version control
Architecture sketches
Collaborative design and reviews
Integrated documentation and decision tracking
Architecture-aware debugging
Why choose Multiplayer for system design and software architecture?
Instant system visibility
See your entire distributed system—components, APIs, dependencies, and environments—automatically and in real-time. No more wasted time updating hand-drawn diagrams or stale wiki pages.
Stronger alignment, smarter decisions
Explore ideas, validate changes, and sanity-check decisions—together. Your team can plan, iterate, and review system updates safely, reducing handoff delays, silos, and the need for endless syncs.
Accelerate onboarding
New engineers, partners, and other teams 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!
Better debugging
Eliminate blind spots and identify root causes faster by understanding service interactions, recent changes, and data flows across your system—no more juggling tabs or grepping through log files.
Prevent technical debt
Ensure your team makes design decisions with full awareness of the existing architecture. Reducing the risk of architectural drift, rework, unnecessary complexity or inefficiencies, and long-term tech debt.
Untangle legacy systems
Auto-document hard-to-understand systems so your team can safely modernize, refactor, or sunset services—without relying on tribal knowledge.
Streamlined security reviews
Make security assessments easier with always-up-to-date system diagrams. Security teams and auditors get a clear view of service boundaries, data flows, and third-party integrations—no manual mapping required.
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.
Future-proof system understanding
Preserve architectural changes, design decisions, and hard-earned knowledge—so your system stays understandable across team changes, reorgs, and scaling efforts.Start for free
