If you’re building a dashboard in Blazor, you need charts. But which library should you pick? There are six serious options in 2026, and they’re very different.

We tested all of them. Here’s what we found.

The Contenders

*Arcadia uses minimal JS only for tooltips, resize, and pan/zoom — core rendering is pure C#.

Rendering: Native Blazor vs JavaScript Wrappers

This is the most important architectural decision. There are two camps:

JavaScript wrappers (Telerik, Syncfusion, DevExpress) — These render charts using a JavaScript library (Kendo, DevExtreme) and bridge to Blazor via JS interop. Pros: mature, feature-rich. Cons: every interop call is a network round-trip in Blazor Server, larger bundle size, doesn’t work in static SSR.

Native Blazor SVG (MudBlazor, Radzen, Arcadia) — These generate SVG markup directly in C#. Pros: zero JS overhead, works in static SSR, smaller bundles, better Blazor Server performance. Cons: building a charting engine from scratch is hard.

Our take: If you’re running Blazor Server behind a corporate firewall (common in enterprise), native rendering is significantly faster. Every JS interop call in Blazor Server is a SignalR round-trip — that adds up fast with interactive charts.

Chart Type Coverage

If you need 50+ chart types, Syncfusion wins. Nobody else comes close.

But here’s the thing: most dashboards use 4-6 chart types. Line, bar, pie, scatter cover 90% of use cases. The question is whether those 4 types are good, not whether you have 50 mediocre ones.

The last row is interesting. No other Blazor library ships pre-composed dashboard widgets — KPI cards, sparklines, bar rankings, progress bars, gauges. These are the components that make a dashboard look like a product, not a science project.

Pricing: The Real Cost

The commercial libraries cost $979-$1,078 per developer per year. That buys you their entire UI suite — 80+ components — even if you only need charts.

Arcadia’s model is different: the Community edition (4 chart types, theme, notifications) is free and open source. Pro ($299/dev/year) adds the full chart suite, dashboard widgets, and Form Builder. That’s 70% cheaper than Syncfusion for the components most teams actually use.

Syncfusion does offer a free Community License for companies under $1M revenue with 5 or fewer developers. But once you grow past that, you’re at $995/dev. Arcadia stays at $299.

Accessibility

This is where the field thins dramatically.

The hidden data table is worth highlighting. When a screen reader encounters an SVG chart, it sees nothing useful. Arcadia renders an invisible HTML <table> alongside every chart with the actual data values. Screen reader users get structured data, not “image.”

If you’re building for government or enterprise clients with accessibility requirements in procurement RFPs, this matters.

Developer Experience

Here’s what it feels like to add a chart in each library:

Arcadia — strongly typed with lambda field selectors:

<HelixLineChart TItem="Sale" Data="@data"
                XField="@(d => (object)d.Month)"
                Series="@series" Height="300" />

MudBlazor — simple but limited to double[]:

<MudChart ChartType="ChartType.Line"
          ChartSeries="@series"
          XAxisLabels="@labels" />

Syncfusion — verbose with nested tags:

<SfChart>
  <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category" />
  <ChartSeriesCollection>
    <ChartSeries DataSource="@data" XName="Month" YName="Revenue"
                 Type="ChartSeriesType.Line" />
  </ChartSeriesCollection>
</SfChart>

All three work. Arcadia and MudBlazor are the most concise. Syncfusion is the most configurable but also the most verbose.

Label Collision Handling

A chart that looks good with 6 data points might look terrible with 30. Labels overlap, ticks pile up, legends overflow.

Arcadia’s layout engine runs a full collision detection pass before rendering: reduce ticks → rotate → abbreviate → skip → fallback to first/last only. It adapts structurally at 4 responsive breakpoints (wide/medium/narrow/compact), not just CSS scaling.

Our Recommendation

If money is no object and you need 50+ chart types: Syncfusion. It’s the most complete.

If you want free and simple: MudBlazor. Great community, good enough for basic charts. But don’t expect advanced features.

If you’re building enterprise dashboards and want the best value: We’re biased, but we built Arcadia specifically for this. Native Blazor rendering, dashboard-first widgets that nobody else offers, WCAG AA accessibility, and $299/year instead of $1,000+.

The Community edition is free on GitHub. Try it and decide for yourself.
