When it comes to creating diagrams in Confluence, teams face a critical challenge: choosing a tool that balances power, flexibility, and ease of use. After years of fragmented solutions and limited options,  Capable Diagrams for Confluence  emerges as the definitive answer - offering the most comprehensive diagram library support available in any Confluence app today.

Why Library Support Matters

In modern knowledge management, visual communication isn't optional - it's essential. Whether you're documenting software architecture, mapping business processes, or illustrating complex workflows, the right diagram makes the difference between clarity and confusion.

But here's the problem: most Confluence diagram apps force you to choose between visual editors and text-based formats, between simplicity and power, between one library and another. Teams end up installing multiple apps, switching contexts, and losing productivity in the process.

Capable Diagrams for Confluence changes everything.

Visual Editors That Feel Natural

Capable Diagrams includes industry-leading visual editors that make diagram creation intuitive and fast:

Excalidraw Integration: The beloved hand-drawn aesthetic that makes your diagrams feel human and approachable. Perfect for brainstorming sessions, wireframes, and collaborative whiteboarding.

Capable Diagrams: While other apps require you to choose between visual tools, Capable Diagrams supports these diagramming workflows, giving teams familiar with this popular tool an easy transition path.

BPMN Visual Modeling: Create professional business process diagrams with dedicated BPMN tools. No more wrestling with generic shapes—use purpose-built process modeling components that follow industry standards.

The Most Comprehensive Diagram Library Collection

Where Capable Diagrams truly shines is in its text-based diagram support. We're not talking about basic Mermaid support - we're talking about  over 20 diagram libraries, more than any other Confluence app on the market.

Core Text Diagram Libraries

Mermaid: The gold standard for diagram-as-code, supporting:

-   Flowcharts and sequence diagrams
-   Class and state diagrams
-   Gantt charts and Git graphs
-   Entity-relationship diagrams
-   User journey maps and timelines
-   C4 architecture diagrams
-   Sankey diagrams and more

PlantUML: The powerhouse for software documentation, including:

-   All UML diagram types (class, sequence, use case, activity, component, deployment, state, timing)
-   Non-UML diagrams (JSON, YAML, network diagrams, wireframes, Gantt charts, mind maps, ERD)
-   Archimate for enterprise architecture
-   Mathematical notation support

C4 Models: Dedicated support for the Context, Container, Component, and Code architectural approach—purpose-built for modern software architecture documentation.

Specialized Technical Libraries

BPMN (Business Process Model and Notation): Native text-based BPMN support for process documentation

GraphViz: Powerful graph visualization for:

-   Directed and undirected graphs
-   Network topologies
-   Dependency visualizations
-   Hierarchical structures

Database Design:

-   DBML  (Database Markup Language) for schema documentation
-   ERD  for entity-relationship modeling

Hardware and Circuit Design:

-   WaveDrom: Digital timing diagrams
-   WireViz: Cable and wiring harness documentation
-   ByteField: Packet and protocol visualizations
-   Symbolator: HDL symbol generation

Network Diagrams:

-   NWDiag: Network topology diagrams
-   PacketDiag: Network packet structures
-   RackDiag: Server rack layouts

Specialized Formats:

-   D2: Modern declarative diagram language
-   TikZ: LaTeX-based technical illustrations
-   Vega & Vega-Lite: Data visualization grammars
-   Structurizr: Software architecture diagrams
-   BlockDiag,  SeqDiag,  ActDiag: Simplified diagram syntaxes

The Complete Package: Why Breadth Matters

This isn't just a feature list - it's about solving real problems. Consider these scenarios:

For DevOps Engineers: Document your infrastructure with C4 models, create network diagrams with NWDiag, visualize CI/CD pipelines with Mermaid flowcharts, and design timing diagrams with WaveDrom - all in one app.

For Software Architects: Write PlantUML for UML diagrams, use Structurizr for architecture documentation, create ERDs with DBML, and visualize data flows with GraphViz - without switching tools.

For Business Analysts: Build BPMN process models, create Mermaid Gantt charts, design user journeys, and collaborate on Excalidraw wireframes - seamlessly integrated.

For Technical Writers: Access every diagram format your developers use, embed live diagrams that update with documentation, and create visual guides that match your team's workflow.

Migration Made Simple: Bring Your Existing Diagrams

One of the biggest barriers to adopting new tools is the migration headache. Capable Diagrams eliminates this friction with comprehensive migration support:

Draw.io for Confluence: Already using Draw.io? No problem. Import your existing Draw.io diagrams and continue working with them in Capable's enhanced environment. You get all your familiar features plus our expanded library support.

PlantUML for Confluence: Migrating from Confluence Data Center to Cloud or from another Cloud PlantUML app? Our PlantUML Migration Tool automates the conversion process, maintaining version history and page structure so nothing gets lost in translation.

Just Add+ for Confluence: Migrating from the Just Add+ Confluence app is easy with our migration tool - simply select the pages and macros you'd like to migrate and click migrate and we handle the rest for you!

Centralized Diagram Browser

Unlike other apps where your diagrams are scattered across pages with no easy way to find them, Capable Diagrams includes a centralized browser that indexes all your diagrams:

-   Search by diagram type, creator, or content
-   Filter by space or date
-   Preview diagrams before opening
-   Quickly locate and manage all visual assets
-   Track diagram usage across your Confluence instance

This seemingly simple feature solves a massive problem: knowing what diagrams exist and where they're used. For teams with hundreds or thousands of diagrams, this is transformational.

Template Library and Sharing

Capable Diagrams comes with an extensive template library covering:

Cloud Architecture Templates:

-   AWS reference architectures (microservices, serverless, container orchestration)
-   Azure solution patterns
-   Google Cloud Platform designs
-   Multi-cloud hybrid architectures

Software Development Templates:

-   Microservices patterns
-   CI/CD pipeline visualizations
-   Database schema starters
-   API architecture diagrams

Business Process Templates:

-   BPMN workflow starters
-   Customer journey maps
-   Organizational charts
-   Project timelines

Networking Templates:

-   Network topology diagrams
-   Rack layout templates
-   Security architecture
-   Data flow diagrams

Create and Share Your Own Templates

But templates aren't just for getting started—they're for maintaining consistency. With Capable Diagrams, you can:

1.  Create custom templates from any diagram
2.  Store them in a shared repository organized by team or purpose
3.  Share across spaces to ensure brand and documentation consistency
4.  Update templates centrally  and have changes propagate to new instances
5.  Control access with different visibility levels (personal, team, organization-wide)

This means your team's hard-won diagram conventions become reusable assets, not one-off creations that get reinvented every time.

Frequently Asked Questions

Q: Can I really use all 20+ diagram libraries, or are some premium features?
A: All libraries are included in every plan. When we say comprehensive support, we mean it.

Q: How hard is it to migrate from Draw.io or other apps?
A: Our migration tools handle the heavy lifting. Most teams complete migration in hours, not days. We provide documentation and support throughout the process.

Q: What if my team prefers visual editing but I need text-based diagrams?
A: Perfect—that's exactly why we built Capable. Your designers can use Excalidraw, your architects can use C4/PlantUML, and everyone works in the same app with consistent output.

Q: Do I need to learn all these diagram formats?
A: Not at all. Start with what you know, use templates for common patterns, and expand as needed. Our AI features help bridge the learning curve.

Q: How does Capable compare on performance with so many libraries?
A: We've optimized heavily. Diagram rendering is up to 5x faster than alternatives, and we use lazy loading so page performance stays excellent even with many diagrams.
