Mermaid vs OpenFlow

Mermaid and OpenFlow DSL solve adjacent but different problems in OpenFlowKit.

Choose Mermaid when

• the diagram must live in Markdown, docs sites, or README files
• your team already reviews Mermaid in pull requests
• external tooling expects Mermaid syntax

Choose OpenFlow DSL when

• the diagram is primarily maintained inside OpenFlowKit
• you want a format closer to the native graph model
• you want fewer compatibility constraints during editing
• you want a better target for OpenFlowKit-specific AI and Studio workflows

Practical difference

Mermaid is a broad ecosystem format.

OpenFlow DSL is an editor-native format.

That usually means:

• Mermaid is better for portability
• OpenFlow DSL is better for fidelity inside this product

Recommended team pattern

If you need both:

• treat JSON or OpenFlow DSL as the editing master
• publish Mermaid as a downstream representation when required

This avoids losing detail every time a diagram moves between ecosystems.

Mermaid.js:

• Renders SVGs based on predefined themes (default, dark, forest, neutral).
• Customizing styles requires inline CSS classes, which can clutter your markdown.

OpenFlowKit:

• Features a full White-Label Design System.
• You can inject Theming tokens dynamically (colors, corner radii, fonts).
• Nodes automatically adopt glassmorphism, shadows, and modern UI treatments without writing a single line of CSS.

2. Interaction and Editing

Mermaid.js:

• Strictly code-in, diagram-out. To move a node, you rewrite the code.
• Layouts are handled automatically by Dagre, which is great but offers zero manual control if a line routes awkwardly.

OpenFlowKit:

• Two-Way Sync: Write code and watch the canvas update, or drag a node on the canvas and watch the code update automatically.
• You get full drag-and-drop capabilities, manual edge routing, and Smart Layouts via ELK.js.

3. Export Options

Mermaid.js:

• Typically exports as SVG or PNG via a CLI or browser extension.

OpenFlowKit:

• Native Exporting to SVG, high-res PNG/JPG.
• Figma Editable: OpenFlowKit can export diagrams directly to your clipboard in a format that pastes into Figma as native, editable vector layers and text objects.

4. Artificial Intelligence

While AI can write Mermaid syntax, iterating on it is difficult.

OpenFlowKit:

• Integrated Flowpilot AI directly into the Command Center.
• You can prompt the AI, generate the canvas, and then manually adjust the final 10% visually instead of trying to perfectly craft a prompt to fix a misaligned node.
• Supports BYOK (Bring Your Own Key) for 7 different AI providers.

Direct Compatibility

We love Mermaid. That is why OpenFlowKit has a native Mermaid Integration. You can paste any existing Mermaid flowchart or state diagram into OpenFlowKit, and it will instantly convert it into editable, styled React Flow nodes.
