Mermaider

Mermaider

Render Mermaid diagrams to SVG in pure .NET. No browser, no DOM, no JavaScript runtime. AOT-ready.

NuGet

A flowchart with two subgraphs, labelled edges and dashed event edges, rendered by Mermaider

Install

dotnet add package Mermaider

Quick start

using Mermaider;

var svg = MermaidRenderer.RenderSvg("""
    graph TD
      A[Start] --> B{Decision}
      B -->|Yes| C[OK]
      B -->|No| D[End]
    """);

// the same diagram as text, for a terminal, a log or a pull-request comment
var text = MermaidRenderer.RenderAscii("""
    flowchart LR
      A[(OrderEvents)] -->|"2/s"| B{{Orders}}
      B --> C[Order]
    """);

Hand it a Mermaid string; get a sanitized, consistently styled SVG back. No interop, no child processes, no headless browsers.

  • Pure .NET, zero interop: just a NuGet reference. No Chromium, no Node.js, no subprocess management.
  • Native AOT: every public API proven in CI on Linux, macOS and Windows.
  • Built-in layout engine: Sugiyama, a zero-dependency layered layout with compound subgraphs and an orthogonal edge router.
  • 24 diagram types: one API, one theming model for all of them.
  • Unified theming: 15 themes, live-switchable via CSS custom properties.
  • Always-on SVG sanitization: allowlist-only, no opt-out.
  • Strict styling mode: enforce your design system on user-authored diagrams.
  • Fast: ~95 µs and ~209 KB allocated to render a simple flowchart end to end.
