Top Blazor Companies for .NET Web Development

Blazor is rapidly emerging as one of the most promising frameworks in the .NET ecosystem. No surprise, since it allows developers to build rich, interactive web applications using C# instead of JavaScript. This is a major advantage, especially for teams already working within the .NET ecosystem. Rather than switching between two languages for front-end and back-end development, Blazor enables full-stack development with a single language.

The growing adoption of Blazor speaks for itself. The number of live websites built with the framework skyrocketed from 12.5K in November 2023 to 35,5K by the beginning of 2025.

With demand rising at this pace, many companies may struggle to hire skilled Blazor developers in-house. Partnering with a specialized software development company can be a faster way to access the expertise needed to deliver scalable, high-performance Blazor applications.

In this article, we’ve compiled a list of top Microsoft Blazor development companies you can trust to bring your .NET web project to life.

This ranking is based on a careful review of 48 Blazor development companies worldwide and provides well-researched, unbiased recommendations. We’ve handpicked the top 10 vendors based on their expertise, track record, reviews, and ability to deliver high-quality .NET web solutions using Blazor. Each profile includes key strengths and areas of focus, so you can quickly evaluate which company best fits your project needs.

Whether you’re building a new web application or migrating an existing one, partnering with the right company can significantly impact the outcome. Here are some important factors to consider when evaluating Blazor development companies.

Choosing a Blazor development company isn’t just about reviewing portfolios and ratings, it’s about asking the right questions to understand whether the team is technically capable, communicative, and aligned with your goals. These questions will help you evaluate their experience, processes, and how well they can meet your specific project needs.

1. What is your hands-on experience with Blazor?
Blazor offers three hosting models: Blazor WebAssembly, Blazor Web App, and Blazor Hybrid. Each one has different architecture and performance implications. Ask the company which model they’ve worked with and in what context. A mature development partner should be able to explain the trade-offs and recommend the best fit based on your app’s requirements.

2. Can you walk us through a recent Blazor project you delivered?
Rather than relying on general statements, ask for real-world examples. A walkthrough should cover the business goals, technologies used, challenges faced (such as performance tuning, client-side logic, or real-time updates), and how the company solved them.

3. How do you approach application architecture and scalability in Blazor?
Blazor apps can become performance-heavy, especially with WebAssembly. Ask how the team handles lazy loading, component reusability, caching strategies, and data transfer between client and server. Their approach to architecture will affect how well your app performs under load and its ability to scale over time.

4. What is your testing and quality assurance process?
A reliable partner takes testing seriously and should perform different types of testing, including unit testing, integration testing, and UI testing, to ensure high-quality software. Ask about the frameworks they use, like xUnit, bUnit (for Blazor-specific components), or Selenium for end-to-end testing. Also, clarify how often they test during the development cycle.

5. What level of support do you offer after the app goes live?
It’s essential to know what happens after launch. Does your potential vendor offer maintenance plans, bug fixing, performance monitoring, and updates when Blazor or .NET evolves? A good Blazor partner should treat launch as the beginning, not the end, of your collaboration.

The answers you get during this evaluation process can reveal a lot about each potential vendor, their technical experience, and their general attitude to projects. Such information will help you distinguish between experienced Blazor developers and those still learning the framework.

Even if a software development company seems promising on the surface, it’s important to look deeper. When evaluating a Blazor development partner, watch out for red flags that may signal potential issues down the road.

Below are some critical warning signs that could impact the success of your Blazor project.

Blazor was released in 2018 and is a relatively new framework in the .NET ecosystem. Working with it requires specialized knowledge. If a company claims to have experience in Blazor but fails to provide relevant case studies or examples of Blazor-based projects, this could be a red flag.

Integrating Blazor with .NET technologies like ASP.NET Core and Azure can be challenging without a strong foundation in .NET. If a company does not have a background in these areas, they may face difficulties delivering you a seamless, scalable solution.

Avoid companies that lack a clear methodology for project management and development. In Blazor development, the framework itself introduces certain complexities that require a structured approach to build scalable and maintainable solutions. For example, managing state in Blazor, especially in Blazor Server, requires careful planning for optimal performance and scalability. A disorganized development process can make it harder to effectively manage these technical challenges.

Additionally, without a defined methodology for testing, deployment, and iterative development, the project may face issues like unexpected bugs, poor-quality code, and extended timelines. To keep the development process structured and efficient, ensure the company uses tools like Azure DevOps or GitHub for version control, continuous integration, and delivery pipelines.

If the company demonstrates slow response times or unclear communication about project timelines, technical limitations, or design choices, it’s a significant red flag. Poor communication can lead to a misunderstanding of the project scope, which can later result in an unsatisfactory end product.

Before partnering with a Blazor development company, find out how they handle daily communication, how often you can check in with the team, and what their processes are for addressing issues. This will help you understand the vendor’s work ethic and see whether it’s a good fit.

Watch out for companies that make unrealistic promises or guarantee results that seem too good to be true. If a company guarantees quick, error-free solutions without describing the necessary phases and actions, they may be underestimating the technical effort required.

A reliable company should be able to provide a realistic development plan with a timeline and outline the testing, optimization, and debugging processes needed to ensure a high-quality application.

Development doesn’t end when the application is launched. Be cautious if a company does not offer maintenance, support, and scalability services after the project is complete. Without this, you risk facing performance and security issues as the application evolves and technology advances. For example, as Blazor continues to evolve, your application may require updates to accommodate new Blazor features or changes to the .NET runtime.

A company that is solely focused on delivering the initial product without offering support for future updates, bug fixes, or performance optimizations is a serious red flag.

While not every good company may be listed on platforms like Clutch, having little to no testimonials or reviews on their website is a red flag. Client feedback is a strong indicator of the company’s credibility and professionalism. A company that doesn’t share its clients’ experiences or lacks verifiable success stories could be signaling underperformance or a lack of trust within the industry.

Reviews, particularly from past Blazor projects, can give you insights into the company’s expertise and technical capabilities. If the company fails to provide such evidence, or if all testimonials seem generic and unsubstantiated, proceed with caution.

N.B. It’s always a good idea to ask for direct references and case studies from clients who have worked on similar Blazor-based applications.

Here are our latest Blazor case studies.

A Spanish ticketing company reached out to us with a request to build a website and mobile apps to streamline the ticket-selling process. To meet these needs, we recommended using Blazor Hybrid with .NET MAUI. This approach allowed us to develop web and native mobile apps for iOS and Android from a single codebase.

Using Blazor Hybrid allowed us to reuse around 90% of the code across all platforms. This helped our team significantly reduce development time and achieve approximately 2.5x cost savings compared to separate native and web development. The remaining 10% was spent on platform-specific features, like custom gesture controls and tailored UI interactions.

Our client, a European startup, contacted us with a request to redevelop their photo-ordering platform and add new features, including custom photo filters and Azure Vision AI service integration. To meet the client’s goals, we redeveloped the mobile app from the ground up using Blazor Hybrid with .NET MAUI. This approach allowed us to reuse the majority of the codebase across platforms and reduce duplicate work.

To optimize cloud costs, Leobit restructured the subscription and usage of cloud resources, activating them only during specific hours to perform necessary jobs. This strategy allowed us to reduce Azure expenses by 75%.
