You might qualify for the Syncfusion Community License: https://www.syncfusion.com/products/communitylicense

Radzen also has a component library available: https://blazor.radzen.com/

https://abp.io/ recently added Blazor to their framework that you might want to check out.

Thank you for your advice. The Syncfusion Community License is certainly interesting and I will keep it in mind (as well as Radzen). Though, frankly, I don't like these "lure into an ecosystem/platform/product with free goodies and then lock in to a very expensive deal" approaches. I prefer a decent progressive pricing tiers model. Re: ABP and Blazor - yes, I read about that, but I think that it is still an experimental feature: https://github.com/abpframework/abp/issues/394.

I didnt specify but we actually mostly use server side Blazor for now. The only issue with it so far is lack of proper hot reload which is annoying but manageable. Otherwise, it's really great. It's kinda an equivalent of Phoenix' LiveView. You only really send diffs over the wire, everything happens on the server, code sharing is very easy and makes developing very, very fast. Sure, SignalR might not be that scalable but IMO unless you're a giant with tens of thousands of active users at any given moment, I wouldn't care.

Interesting and good to know. Thank you for your additional clarifications. I would love to get my hands dirty with Blazor and many other technologies. The problem with being a very early-stage startup, despite being very tempting to jump the cutting edge bandwagon and (try to) use as many cool technologies as you can get your hands on, is to keep in mind the importance of risk management. More often than not, it makes sense to select a "boring" technology stack (http://boringtechnology.club), at least, for all or certain foundational layers or components of the larger system.
