Arcadia Controls
Pros:
- Pure SVG rendering from C# — no JavaScript runtime required for charts
- Smallest bundle size of any commercial option since there is no JS chart engine
- Full WCAG 2.1 AA accessibility on every chart type (hidden data tables, keyboard nav)
- MCP server for AI-assisted code generation — describe a chart in English, get Blazor code
- Multi-targets .NET 5 through .NET 10 (widest framework support)
- Free Community Edition with 4 chart types, sparklines, and notifications
- 7 purpose-built dashboard widgets (KPI Card, Gauge, Sparkline, etc.)
Cons:
- 16 chart types vs 30+ for Telerik/Syncfusion — fewer niche chart types
- Newer library with a smaller community than established players
- No built-in data grid component (focused on charts and dashboards)
Best for: Teams that want zero-JS chart rendering, strong accessibility, AI tooling, and a budget-friendly price point.
Pricing: Free (Community) / $299 (Pro) / $799 (Enterprise) per developer per year.
Telerik UI for Blazor
Pros:
- Massive component library with 100+ components beyond just charts
- 30+ chart types covering nearly every visualization need
- Strong enterprise track record and documentation
- Built-in grid, scheduler, editor, and more
Cons:
- JavaScript-based canvas rendering for charts — larger bundle, not ideal for SSR
- Expensive at $1,249+ per developer per year
- No free tier or open-source option
- Heavier runtime due to JS interop overhead
Best for: Large enterprises that need a comprehensive all-in-one UI suite and don’t mind the price tag.
Pricing: Starting at $1,249/developer/year.
Syncfusion Blazor
Pros:
- 35+ chart types — the most chart variety of any Blazor library
- Comprehensive component suite (80+ components)
- Community license available for small businesses (under $1M revenue)
- Good documentation and samples
Cons:
- JavaScript-dependent canvas rendering
- Community license has strict revenue limits
- Complex licensing model
- Can be heavy on bundle size
Best for: Teams that need the widest variety of chart types and qualify for the community license.
Pricing: Community (free with restrictions) / $995+ per developer per year.
MudBlazor
Pros:
- Fully open source (MIT license)
- Active community and frequent updates
- Clean Material Design aesthetic
- No licensing costs
Cons:
- Only 6 chart types — very limited for dashboards
- Charts use JS interop, not pure Blazor rendering
- No dashboard widgets, form builder, or notification system
- Limited .NET version support compared to Arcadia
- Accessibility coverage is incomplete
Best for: Hobby projects or MVPs where you need free charts and Material Design, and don’t need extensive chart types.
Pricing: Free (MIT).
Rendering Approach: Why It Matters
The biggest architectural difference between these libraries is how they render charts.
Arcadia Controls generates SVG elements directly from C# Blazor components. There is no JavaScript chart engine. This means:
- Charts render on the server during SSR without a JS runtime
- No SignalR/WebSocket overhead for chart interop calls
- Smaller deployed bundle size
- Charts are part of the Blazor component tree — they participate in standard Blazor lifecycle and diffing
Telerik and Syncfusion use JavaScript canvas-based chart engines (similar to Chart.js or Highcharts) wrapped in Blazor components. Data is marshaled from C# to JS via interop. This adds latency and bundle weight but enables more complex visualizations.
MudBlazor uses a lighter JS-based SVG approach but still requires interop.
Bundle Size Comparison
| Library | Chart JS payload | Total chart bundle |
|---|---|---|
| Arcadia Controls | 0 KB | ~45 KB (DLL only) |
| Telerik | ~180 KB | ~350 KB |
| Syncfusion | ~200 KB | ~400 KB |
| MudBlazor | ~60 KB | ~120 KB |
Approximate sizes. Arcadia’s zero-JS approach means the only payload is the .NET assembly itself.
Accessibility
Accessibility is often overlooked in chart libraries but critical for enterprise apps.
| Feature | Arcadia | Telerik | Syncfusion | MudBlazor |
|---|---|---|---|---|
| Hidden data tables | Yes (all charts) | Some charts | Some charts | No |
| Keyboard navigation | Full | Partial | Partial | Minimal |
| Screen reader labels | ARIA labels on all elements | Partial | Partial | Minimal |
| prefers-reduced-motion | Respected | Not always | Not always | No |
| WCAG 2.1 AA certified | Yes | No | No | No |
AI Integration
Arcadia Controls is the only Blazor chart library with a built-in MCP (Model Context Protocol) server. This means AI assistants like Claude, ChatGPT, and GitHub Copilot can:
- Generate chart code from natural language (“show me a bar chart of monthly revenue”)
- Suggest chart configurations based on your data shape
- Help debug chart rendering issues
No other Blazor chart library offers this capability today.
Our Recommendation
- Choose Arcadia Controls if you want zero-JS rendering, strong accessibility, AI tooling, and the best price-to-value ratio. The free Community Edition lets you evaluate before committing.
- Choose Telerik if you need 100+ components in one suite and budget is not a concern.
- Choose Syncfusion if you need 35+ chart types and qualify for their community license.
- Choose MudBlazor if you need a free, open-source option and only need basic charts.
