Documentation

Architecture documentation tool

Generate architecture documentation with AI. System context, service topology, data flows, and deployment diagrams — in Mermaid & PlantUML.

Documentation capabilities

AI diagram generation

Describe your system → get structured diagrams. No diagramming skills needed.

Multi-level views

C4 context, container, and component diagrams for different audiences.

Sequence flows

Document API flows, authentication, and business processes step by step.

Data flow maps

Trace data through pipelines, transformations, and stores.

Version-controlled

Store in Git. Documentation evolves with your code.

Export options

SVG, PNG, source code, or full ZIP with architecture specs.

How it works

Design, document, and maintain your architecture in one continuous workflow.

1

Design architecture visually

Build your architecture using Mermaid or PlantUML in Cybewave's editor. Start from scratch or let the AI assistant generate an initial diagram from your description. See your system take shape in real time with instant rendering and syntax validation as you type.

2

Generate documentation automatically

The AI analyzes your diagrams and produces structured documentation—system overviews, component descriptions, integration narratives, and data flow explanations. Documentation is generated as a byproduct of diagramming, not as a separate manual task requiring additional effort.

3

Keep it in sync with your system

When your architecture evolves, update the diagram and regenerate documentation instantly. Export to your wiki, Git repository, or documentation platform. Your architecture docs stay current because maintaining them takes seconds, not hours of rewriting and reformatting.

Use cases

A documentation tool that fits into how engineering teams actually work.

Engineering handbook maintenance

Keep your engineering handbook's architecture sections current without dedicated documentation sprints. Update diagrams as the system changes, and the documentation regenerates to match—teams always reference accurate, up-to-date material.

Onboarding documentation

Give new engineers a clear picture of your system from day one. Auto-generated architecture docs provide the system context, service relationships, and data flows that new hires need to become productive quickly.

Architecture decision records

Pair ADRs with diagrams showing the before and after of each architectural decision. Document not just what changed, but visualize the structural impact—making decision history tangible and reviewable for future teams.

System inventory management

Maintain a living inventory of all services, databases, queues, and external integrations. The documentation tool produces structured component lists with descriptions, ownership, and dependency information derived from your diagrams.

Disaster recovery documentation

Generate and maintain DR documentation showing system dependencies, failover paths, and recovery procedures. When infrastructure changes, update the diagram and get refreshed DR docs that reflect the current architecture.

Vendor integration documentation

Document how third-party services integrate with your system—API boundaries, data flows, authentication mechanisms, and failure modes. Keep this documentation current as vendor APIs change and new integrations are added.

Why the right documentation tool matters

Architecture documentation tools should reduce work, not create it. Most tools treat documentation as a separate deliverable—you design in one tool, then manually write up what you designed in another. This disconnect is why documentation drifts from reality within weeks. The best tool generates docs as a byproduct of diagramming, collapsing two tasks into one and eliminating the gap where staleness creeps in.

The hidden cost of poor documentation tooling is measured in interruptions. Without current architecture docs, every question about system structure becomes a synchronous conversation—a Slack message, a meeting, a shoulder tap. These interruptions compound across a growing team. A documentation tool that keeps architecture descriptions accurate and accessible turns synchronous questions into self-service answers.

Effective documentation tools also enforce consistency. When every service, integration, and data flow is documented using the same generated format, teams develop a shared vocabulary for discussing architecture. New engineers learn the system faster because every component is described with the same level of detail, in the same structure, using the same visual conventions throughout.
