Blazor Blueprint vs Radzen Blazor Components
These two are peers, and this is the closest comparison of the three. Both are free and permissively licensed, and neither is meaningfully larger. Radzen still has the spreadsheet and far more chart types, and sells a visual designer on top. Blazor Blueprint goes deeper on the design system, the headless layer and form inputs — and as of 4.1 it ships the Gantt chart, the pivot grid, barcodes and QR codes that used to be the gap between them.
Written by the Blazor Blueprint team. We have tried to be fair rather than flattering — every claim about Radzen Blazor Components comes from their own published material, linked at the foot of the page, and was checked on 2026-09-20.
The short answer
Neither library is the right answer for everyone. Here is when each one wins.
Choose Radzen if
- You need a spreadsheet. Radzen ships one with formulas; we do not, and it is now the only one of their three heavy data components we are missing.
- Charts are central to your application. Radzen's set is deeper than ours — thirty-plus types including Sankey, treemap and gauges.
- You want a visual designer. Radzen Blazor Studio builds Blazor apps visually with AI agent support. We have nothing like it and are not trying to.
- You want a map component out of the box. Radzen wraps Google Maps; we ship nothing geographic.
- A long client list reassures your buyer. Radzen names Microsoft, NASA, Porsche, Dell, Siemens and DHL among its users.
Choose Blazor Blueprint if
- You want the shadcn/ui design language, and theme portability with the React ecosystem through tweakcn.
- You want to own the styling. The headless primitives carry the behaviour and leave the appearance entirely to you.
- You would rather start from a screen than a control. 64 blueprints are whole screens — sign-in, billing, settings, dashboards.
- Your forms need more than the basics: currency, masked, one-time-code, tag, cascading and tree inputs each ship as their own component.
- Your legal team asks about patents. Apache 2.0 carries an express patent grant; MIT is silent on patents.
Side by side
A dash means the library does not advertise it, not that it cannot do it — we only know what each project publishes.

Component counts are not comparable between libraries. Every project counts differently — variants, sub-components and layout helpers all get counted by somebody. Treat the numbers as a rough scale, not a score.

Every row is a capability, not a component name. Hover a tick to see what each library calls it, and click ours to open its documentation. This is the tightest of our three comparisons — expect a lot of rows where both sides tick.

We have annotated our own gaps and not Radzen Blazor Components's, because we know our library and not theirs. Several of their crosses will have equally good answers — a parameter on another component, or a pattern their design language handles differently. Take the crosses in their column with that in mind, and check anything that decides it for you.
