VERDICT

Should I use MudBlazor?

Blazor Component Library based on Material Design. MudBlazor is easy to use and extend, especially for .NET devs because it uses almost no Javascript. - mudblazor.com

Worth it. Buy it if your team builds Blazor apps on .NET — the entire library is free, MIT-licensed, and widely adopted. Avoid it if you need a vendor with support SLAs, strict CSP compliance, or you are not on the Microsoft stack.

No paid support: fixes depend on volunteer maintainers; 'slow development' debates exist.

Donation-funded roadmap; sponsorship drying up is a real user concern.

Inline CSS blocks strict Content-Security-Policy deployments; workaround needed.

Switching libraries later means rewriting UI; Blazorise publishes a migration guide.
