Blazor Blueprint vs Telerik UI for Blazor
Telerik is the broadest of the three and the only one you pay for. It ships things no free Blazor library does — a spreadsheet, a file manager, a diagram surface, document processing for PDF and Word — along with support contracts and stated accessibility conformance. Blazor Blueprint is free and Apache 2.0, and as of 4.1 it closes two of the old gaps with a Gantt chart and a pivot grid. The question is whether you need what the fee still buys.
Written by the Blazor Blueprint team. We have tried to be fair rather than flattering — every claim about Telerik UI for Blazor 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 Telerik if
- You need the heavy components we still do not have. Spreadsheet, file manager, diagram, maps, gauges and document processing for PDF, Word and Excel. We now ship a Gantt chart and a pivot grid, but none of those six.
- You need a support contract with a response time in it. Telerik's tiers run from 72-hour response to 24-hour with unlimited incidents and phone support. We have GitHub issues and goodwill, and that is not the same thing.
- You need stated accessibility conformance on paper. Telerik publishes conformance with WCAG 2.2, WAI-ARIA and Section 508. We build to those standards but publish no conformance report, and for public-sector procurement that difference matters.
- Your designers work in Figma. Telerik ships Figma UI kits and a ThemeBuilder. We do not.
Choose Blazor Blueprint if
- The licence cost is real money to you. Telerik lists from roughly $734 to $1,028 per developer per year, and perpetual licences ended in June 2026 — it is a subscription now. Blazor Blueprint is Apache 2.0 and costs nothing.
- You do not want licence management. No seat counting, no renewal date, no procurement cycle, nothing to audit.
- You want to read and change the source. All of it is on GitHub under Apache 2.0 — fork it, patch it, ship it.
- You want the shadcn/ui design language and a headless layer underneath it.
- You are building the common case rather than the exotic one. Most applications need forms, tables, navigation and dialogs, not a spreadsheet engine.
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. Telerik is the broadest library here, so expect the most crosses in our column of any of the three comparisons.

We have annotated our own gaps and not Telerik UI for Blazor'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.
