Blazor component libraries: free or paid, and what each choice really costs

Every Blazor business application needs the same things: a data grid, forms, date pickers, dialogs, charts. Building them yourself takes weeks. So the first real decision on a Blazor project is usually not architecture, but which component library to use, and whether to pay for one.

It is a decision you make once and live with for years. Changing the library later means touching almost every screen.

The options

Library	Licence	Cost	Strengths	Watch
QuickGrid	MIT, from Microsoft, part of ASP.NET Core	Free	A fast, simple data grid with sorting, paging and virtualisation	It is only a grid
Fluent UI Blazor	MIT, from Microsoft	Free	The Microsoft 365 look, accessibility	Fewer heavy data components than the commercial suites
MudBlazor	MIT, open source	Free	Material design, many components, the largest community (over 10,000 stars on GitHub)	Maintained by the community; major versions bring breaking changes
Radzen Blazor	MIT, open source	Free	A wide set including a data grid, scheduler and charts, backed by a company	Fewer advanced grid features than the paid suites
Telerik UI for Blazor	Commercial	From $849 per developer per year	A very large set, an advanced grid, support with response times	A subscription for every developer
Syncfusion Blazor	Commercial	Free community licence for small companies, paid otherwise	A very large set, reporting, document tools	The community licence ends when the company grows

Syncfusion’s community licence covers companies with less than $1 million in annual revenue, five or fewer developers and ten or fewer employees. Once you outgrow it, you need a paid licence. DevExpress is another commercial suite in the same league.

What the price really is

The licence is the visible part. For a team of four developers, Telerik costs about $3,400 a year at list price, and MudBlazor costs nothing. But that is not the whole comparison:

• What is missing has to be built. Excel export, grouping with totals, a scheduler, a pivot table. If the free library does not have it, a developer builds it, and a week of a senior developer costs more than a year of licences.
• Support. With a paid suite, someone answers when the grid misbehaves before a deadline. With an open-source library, you open an issue and wait, or fix it yourself.
• Upgrades. Every .NET release, the library has to follow. Big vendors and the big open-source projects usually do. Smaller projects sometimes do not.

Check the licence terms for how many developers need a seat. That depends on the vendor, and on who touches the screens.

When free is enough

For most internal business applications: forms, tables with filters and paging, dialogs, simple charts. Often even Microsoft’s built-in QuickGrid is enough for the tables:

<QuickGrid Items="orders" Pagination="pagination">
    <PropertyColumn Property="@(o => o.Number)" Title="Order" Sortable="true" />
    <PropertyColumn Property="@(o => o.Customer)" Sortable="true" />
    <PropertyColumn Property="@(o => o.Total)" Format="N2" />
</QuickGrid>

<Paginator State="pagination" />

@code {
    private PaginationState pagination = new() { ItemsPerPage = 20 };
}

Add MudBlazor or Radzen for the rest of the components, and you have a complete application without a licence.

When paying pays off

• Heavy data screens. Grids with grouping, aggregates, editing like a spreadsheet, export to Excel and PDF, tens of thousands of rows.
• Specialised components. Schedulers, Gantt charts, pivot tables, reporting.
• Deadlines and support. When a blocked screen costs more than the licence, an answer within a day is worth paying for.
• Customers who ask about the vendor. In some industries, a supported commercial component is easier to explain than an open-source one.

Avoid the expensive mistakes

• One library per application. Mixing two means two styles, two sets of updates and twice the weight in the browser.
• Keep business logic out of the components. Rules belong in services. Then a later switch of the library touches the screens, not the logic.
• Try the hardest screen first. Not the login page, but the big grid your users work in all day. That screen decides whether the library fits.
• Watch performance. A heavy grid with thousands of rows is a common cause of a slow Blazor application. More in our article on why Blazor apps get slow.

Five questions before you choose

1. What is the most demanding screen in the application, and does the library handle it?
2. How many developers will work on the screens, and what does that mean for the licence?
3. Do you need components the free libraries do not have, such as a scheduler, pivot or reporting?
4. Who helps when something breaks a week before go-live?
5. How quickly has the library followed past .NET releases?

If Blazor itself is still an open question, start with Blazor vs Angular or Blazor vs React.

How we work

ProCoding is a .NET studio from Split, Croatia. We have been shipping Blazor to production since 2020, and we have no reason to push one library over another. We help you choose, build new Blazor applications, and speed up the slow screens in existing ones. The first step is a free 30-minute call.
