The Core Question
Blazor WASM is Microsoft's flagship client-side framework. It runs C# in the browser, gives you a full component model, and lets .NET developers build SPAs without touching JavaScript.
But here is the uncomfortable truth: for content sites, Blazor WASM is the wrong tool. Every visitor downloads 512KB+ of runtime, waits 2 seconds for the boot sequence, and pays a hydration cost on every navigation.
Dax Pro takes the opposite approach: compile the C# at build time, ship pure HTML. Zero runtime. Zero hydration.
Benchmark: Head-to-Head
| Metric | Dax Pro | Blazor WASM |
|---|---|---|
| First Contentful Paint | ~50ms | ~2100ms |
| Time to Interactive | ~80ms | ~2800ms |
| JS payload | 0KB | 512KB+ |
| Build time (11 pages) | ~120ms | ~8s |
| Lighthouse Performance | 100 | 70–85 |
| Lighthouse SEO | 100 | 85–90 |
| Cold start | N/A | 2s WASM boot |
| Server requirement | Static CDN | WASM-capable host |
On a 3G mobile connection, Dax Pro serves the first paint before Blazor WASM has finished downloading its runtime. On a fast connection, Dax Pro's Lighthouse score is 100 before Blazor's hydration finishes.
Why Blazor WASM Still Matters
To be fair: Blazor WASM is the correct choice for:
- Interactive dashboards — real-time data binding, complex state
- Admin panels — authenticated SPAs with routing
- Line-of-business apps — offline-capable, C# end-to-end
- Anything with a
that mutates state every second
The Dax Pro Alternative
Dax Pro is built on the open-source DAX SSG engine — a single Program.cs file, zero dependencies, pure C#. It compiles your markdown content into semantic HTML at build time. The output is served from any static CDN: Netlify, Vercel, Azure Static Web Apps, Cloudflare Pages.
No WASM boot. No hydration. No client-side .NET runtime. Just HTML, CSS, and zero KB of JavaScript.

Blazor WASM is a great framework. It is not a great content platform. For content sites that need speed, SEO, and zero maintenance — Dax Pro is the right tool.
