The other mode of Blazor, server side, is where Blazor really shines. Performance is very fast on the client, and it's a much simpler experience for development that traditional SPA while having a very similar programming model. It's simpler partly because of the cohesive much simplified stack, and partly because for most simple one client apps you don't need to create a server API with all the extra work and issues that brings vs having your server side data in process. Blazor WASM is still unfortunately slow on load, however the recent Steve Sanderson video on Blazor in .NET 6 showed impressive client runtime performance once loaded, by doing virtualized UI access to in process Sqlite for a truly native client performance much better than the current gen SPAs and getting back to how good software used to be, literally instant scrolling over tens of thousands of records. But Blazor server is really excellent, recommend it.
