# Blazorise: A Provider-Agnostic Blazor Component Library With a Dual Licence > Blazorise wraps Bootstrap, Tailwind, Bulma, Material, AntDesign and Fluent UI 2 behind one strongly-typed C# component API. The install is short, but the licence terms and the CSS coupling are what decide whether it fits. **Megabit/Blazorise** — Blazorise is a component library built on top of Blazor with support for CSS frameworks like Bootstrap, Tailwind, Bulma, AntDesign, and Material. - Repository: https://github.com/Megabit/Blazorise - Website: https://blazorise.com/ - Stars: 3,535 · Forks: 535 - Language: C# - License: NOASSERTION - Published: 2026-09-23 · Updated: 2026-09-23 · Language: en - Canonical page: https://hysenlabs.com/projects/megabit-blazorise ## The problem Blazorise solves: one component API, several CSS frameworks A Blazor application that uses raw Bootstrap markup ties every component to Bootstrap's class names. Switching to Tailwind or Bulma later means rewriting the markup of each component, not swapping a stylesheet. Blazorise's answer is a provider layer: the component API stays the same and a provider package supplies the framework-specific rendering. The README states the project provides "a consistent, strongly-typed component API across popular CSS frameworks, allowing you to build with Bootstrap 5, Tailwind CSS, Bulma, Material, AntDesign, or Fluent UI 2 without rewriting your application." That is the whole pitch, and it is a narrow one. It is not a design system with its own visual identity; it is an abstraction over frameworks that already have one. The audience is therefore specific: .NET teams already committed to Blazor who want to write UI in C# and who have not fully settled on a CSS framework, or who need to support more than one. If you have already standardized on a single framework and are happy writing its markup directly, the provider layer is overhead you pay for flexibility you will not use. ## How the provider architecture actually works Three pieces are visible in the repository and the README. First, a core package, Blazorise, which holds the component definitions and the shared CSS file blazorise.css. Second, a provider package per framework: the README lists seven, Blazorise.Tailwind, Blazorise.Bootstrap, Blazorise.Bootstrap5, Blazorise.Bulma, Blazorise.Material, Blazorise.AntDesign and Blazorise.FluentUI2. Third, optional icon packages such as Blazorise.Icons.FontAwesome, which ship their own static assets under _content/. At runtime the wiring happens in two places. In Program.cs, a fluent chain registers the core services and then the provider: AddBlazorise().AddBootstrap5Providers().AddFontAwesomeIcons(). In the host page, you link the framework's own CSS plus two Blazorise stylesheets, one generic and one provider-specific. The generic file and the provider file are both required; linking only Bootstrap's CSS leaves the Blazorise-specific styling missing. The README also notes that Blazorise "loads any additional JavaScript it needs dynamically once a component needs it", so the JS is not a single bundle you reference up front. That has a practical consequence the README flags itself: resources must be served relative to the app root, and in Blazor Server you need app.UseStaticFiles();. The README points to issues #3122 and #3150 for people who hit trouble here, and mentions extra setup for PWA and offline scenarios. ## Installing Blazorise with Bootstrap 5 and FontAwesome The README's quick start uses Bootstrap 5 with FontAwesome 6 icons. Start by adding the provider package and the icon package to your project. Two commands, one per package: ```bash dotnet add package Blazorise.Bootstrap5 dotnet add package Blazorise.Icons.FontAwesome ``` Next, the stylesheets. Add these to index.html for Blazor WebAssembly, _Host.cshtml for Blazor Server, or App.razor for a .NET 8+ Blazor Web App, inside the head section. The Bootstrap link is the framework's own CDN file; the last two are Blazorise's core and provider stylesheets: ```html ``` That ?v=2.3.1.0 query string is cache busting. The README says it "matches the current Blazorise package version (2.2.3)" and tells you to update it whenever you upgrade the packages. Note the mismatch in the README's own text between the query value and the stated version; treat the query string as something to keep in sync manually rather than something the tooling fixes for you. Then add the namespace to _Imports.razor so components resolve without a per-file using: ```cs @using Blazorise ``` Finally, register the services in Program.cs. The usings come first, then the chain: ```cs using Blazorise; using Blazorise.Bootstrap5; using Blazorise.Icons.FontAwesome; ``` ```cs builder.Services .AddBlazorise() .AddBootstrap5Providers() .AddFontAwesomeIcons(); ``` A first real use is the counter page from the README. It exercises a heading, a paragraph and a button, which is enough to confirm the provider is wired correctly: ```razor @page "/counter" Counter Current count: @currentCount @code { private int currentCount; private void IncrementCount() { currentCount++; } } ``` If the button renders styled and the count increments, the provider chain, the stylesheets and the JS loading path are all working. If it renders unstyled, the usual cause is a missing provider CSS link or a static-files configuration problem on the server. ## The dual licence is the first thing to read, not the last The repository's licence field reports NOASSERTION, and the README describes Blazorise as "source-available" rather than open source. It is dual-licensed: use is governed by LICENSE.md or by a commercial licence, "depending on your scenario". The README does not enumerate which scenarios require the commercial licence, and it does not state what happens to applications that fall outside the free terms. That ambiguity is the single largest adoption risk here, and it is not a technical one. What the commercial subscription buys is concrete: access to Blazorise Themes, access to Blazorise Blocks, premium support through the Blazorise Support forum, dedicated support with response times of either 24 or 16 hours depending on plan, and priority fixes and feature requests. The README adds that some features may be exclusive to specific subscription tiers. So the free path and the paid path are not the same product with different support levels; the paid path includes assets that do not exist in the free one. This is not legal advice and the README is not a substitute for reading LICENSE.md. But the practical point stands: a team that assumes "source-available" means "MIT-like" is making an assumption the README does not support. Read LICENSE.md before the first commit, not after the first release. ## Where Blazorise is the wrong choice The provider abstraction has a cost. Every component renders through the provider, so the markup you get is the provider's markup, and styling that reaches past Blazorise's props means working against the abstraction rather than with it. If your design calls for heavy custom CSS on top of a component, you are paying for a layer you are also fighting. Charts are the clearest gap in the available documentation. The related searches include "blazorise charts" and "Blazorise svg chart", but the README, the highlights and the component examples shown here do not mention a chart component at all. That does not prove none exists, but it does mean the README is silent on it, and a team whose first requirement is charting should confirm against the documentation before assuming it is covered. The same applies to any component you consider essential: the README shows a heading, a paragraph, a button and the start of a text input, and the component reference lives at blazorise.com/docs rather than in the repository README. There is also a maintenance-cost angle the README itself creates. The cache-busting query string on the stylesheet links is manual, and the README's own example shows a value that does not match the version it names. Teams that upgrade frequently will be editing host pages by hand each time, and forgetting leaves stale CSS in the browser. ## Blazorise against MudBlazor and Radzen The most common comparison searches are "blazorise vs mudblazor" and "blazorise vs radzen". The README covers Blazorise in detail and the alternatives appear only as names in search data, so the honest framing is architectural rather than feature-by-feature. Blazorise's distinguishing choice is that it does not ship its own visual language. It sits on top of Bootstrap, Tailwind, Bulma, Material, AntDesign or Fluent UI 2 and delegates the look to them. MudBlazor and Radzen, by contrast, are self-contained component libraries with their own design system: you adopt their look and you get components that are styled consistently out of the box, without a separate CSS framework underneath. That is a real difference in approach, not a quality ranking. If you want a library that decides the visual style for you, a self-contained library is the shorter path. If you already have a Bootstrap or Tailwind design system and want Blazor components that render into it, Blazorise's provider model is the one built for that case. The second difference is licensing posture. Blazorise is dual-licensed with a commercial tier that carries themes, blocks and support response times. Teams that need a permissive licence with no paid tier should verify the terms of whichever library they pick, including this one. ## Maintenance, upgrades and what the repository shows The last push to the default branch was on 2026-09-23, and the repository is not archived. The release list available here is thin and old: 0.9.0-preview4 on 2020-04-18 followed by 0.9.0 the same day. That is a six-year gap between the listed releases and the current work, which means the release list is not a reliable indicator of what is shipping. The README's own stylesheet example references version 2.3.1.0 in the query string while describing the package version as 2.2.3, so the versioning picture in the README is inconsistent and should be checked against NuGet rather than trusted from the README alone. The repository layout suggests a conventional .NET solution: Blazorise.slnx, a Source/ directory, Tests/, Demos/, Documentation/, Build/, and a Directory.Packages.props for central package version management. Directory.Packages.props matters for upgrade cost: if your solution uses central package management, Blazorise versions are pinned in one file rather than scattered across project files, which makes the mechanical part of an upgrade easier. The manual part, the cache-busting query strings in your host pages, is not covered by that. On upgrade cost generally, the README gives no migration guide, no breaking-change policy and no rollback instructions. Those may exist in the documentation site; the README does not link to them from the installation section. ## Conclusion Adopt Blazorise if your team writes Blazor in C# and wants to keep the CSS framework as a swappable provider rather than a hard dependency baked into every component. Skip it if you need a permissively licensed library with no commercial tier, or if you need charts: the README lists no chart component, so verify that against the documentation before committing. Before starting, read LICENSE.md and confirm which of your scenarios fall under the commercial terms, then check that your provider package (Blazorise.Bootstrap5, Blazorise.Tailwind and so on) matches the CSS you actually ship. ## FAQ ### Is Blazorise free? Blazorise is dual-licensed. The README says use is governed by LICENSE.md or a commercial licence depending on your scenario, and commercial subscriptions add themes, blocks, premium support and priority fixes. The README does not list which scenarios require the commercial licence. ### Is Blazorise free for commercial use? The README does not answer this directly. It states that use is governed by the terms in LICENSE.md or a commercial licence depending on your scenario, so the applicable terms have to be read from LICENSE.md rather than inferred from the README. ### Is Blazorise open source? The README describes Blazorise as a source-available project rather than open source, and the repository's licence field reports NOASSERTION. The README says ongoing development is supported by partners, subscribers and community contributors. ### Which Blazor UI library is the best? The README makes no comparison claim. It presents Blazorise as a provider-agnostic component library with a consistent C# API across several CSS frameworks, and leaves the choice to the reader. ### What are the alternatives to Blazorise? The README does not name alternatives. Search data around the project pairs it with MudBlazor and Radzen, which are self-contained component libraries with their own design systems, whereas Blazorise delegates the visual layer to a CSS framework provider. ## Sources - [Issues](https://github.com/Megabit/Blazorise/issues) - [Megabit/Blazorise on GitHub](https://github.com/Megabit/Blazorise) - [Project website](https://blazorise.com/) - [README](https://github.com/Megabit/Blazorise/blob/master/README.md) - [Releases](https://github.com/Megabit/Blazorise/releases) --- Hysen Labs editorial analysis, written from the project's own repository and release notes.
