As grandparent said, Blazor optimized for fast delivery. For public products you will have places where you should care about interactivity a lot. Their solution is interop with JS. You may try WASM but it’s definitely slow for UI.

WASM good for complicated tools, but you better probably with other language if you looking for next Figma.

Hybrid approach which is default have two issues. - round trip to the server. That’s not nice for interactivity and responsiveness. - hybrid hydration model is needlessly complicated. And again it will not fully solve your problem when you need to go extra mile.

Overall cold start for WASM require large payload, for Hybrid you need Websockets for updates. That sucks outside of cities or on junkie mobile. Not for public product.

Working with Blazor from Net Core 2.2

For internal tooling, or B2B where you don’t care that much is very efficient.
