Blazor for cross-platform development in 2026
Blazor enables cross-platform development in 2026 by letting engineers build web and desktop applications. Learn about the different hosting models, their trade-offs in performance, scalability, connectivity, and security.
Blazor is for organizations that need more flexibility right away and modern architecture sometime soon.
Modern organizations often maintain distributed teams and cover all different customer needs & preferences. These range from extensive desktop capabilities to immediate, browser-based access at any time, anywhere – with innovation, customer expectations have become more demanding.
Regulated industries go with desktop applications for granular data control and unstable connection avoidance. At the same time, going with web services might offer a more straightforward path to updating and upscaling, as well as providing universal accessibility.
.NET provides an ecosystem for projects from simple internal tools to enterprise-grade business applications. Being built on the .NET platform, Blazor allows software development to use the same programming language for both front-end and back-end development, thus accelerating code reuse.
Including multiple hosting models, it adapts to different business requirements – web, mobile, and desktop. Blazor guarantees both flexibility and scalability to align with your specific goals.
In 2025, the evolving software landscape will demand more efficiency, flexibility, scalability, as well as security. So, let’s get into more detail.
Blazor development: hosting models
Let’s discuss the three hosting models to choose from when going with Blazor for software development:
Blazor Server
In the Blazor Server, the application’s state management and execution are happening on the server directly. The client mainly handles the rendering, while the user interaction takes place through the SignalR connection in real-time.
| Key benefits | – the client only loads minimal footprints, which makes initial loads extremely quick – the server-side data storage (and logic) sensibly reduce the exposure to vulnerabilities |
| Key downsides | – every single user interaction is triggering a round-trip server request, which means real-time performance mainly depends on the network’s speed – a high user count can increase server load, as all the processing on the server’s side (large-scale deployments often require horizontal or vertical scaling) |
Blazor WebAssembly or WASM
In the Blazor WebAssembly, the applications are powered by the WASM runtime and running on the client’s side. The app (and the .NET runtime) is both downloaded and executed locally in browser’s WASM runtime, which provides a rich and interactive user experience with minimal server involvement.
| Key benefits | – once downloaded, the application can run in unstable connectivity conditions or offline – with logic being run on the client’s side, only static files and specific API endpoints are handled on the server’s side, which reduces resource utilization |
| Key downsides | – the files (both application and runtime) can be quite large, which may impact first-time user experience on rather slow networks – it’s supported by most modern browsers, but both legacy and specialized environments may present compatibility challenges |
Blazor Hybrid
By using Blazor Hybrid, you can easily integrate Blazor elements into native web-based/mobile/desktop apps. This approach is appealing when sharing user interface or logic (Blazor-based components) across projects (native and web mainly).
| Key benefits | – сode can be shared across desktop, mobile and web applications, thus reducing code duplication and speeding up development – when running within a native container, you access native APIs for richer device-specific functionality (e.g. camera) |
| Key downsides | – as of late 2024, there is no official .NET MAUI Linux support, which means coverage requires alternative solutions (Avalonia UI, Electron, Photino) – separate applications are built and deployed, as well as maintained for each platform separately |
Going hybrid: desktop and web from one codebase
One of Blazor’s most powerful (and useful) features is, among other things, the ability to enable code reuse. Software developers can write code once and deploy it across desktop systems and cloud-based web services. What’s important to mention – this can be achieved with the same team without hiring additional specialists. This way, software engineers can maintain unified codebases without duplicate business logic and elements.
Another thing, by structuring your application as a Modular Monolith, you prepare for future cloud evolution. As isolation or scalability needs grow, the modules can be incrementally transitioned into microservices.
As of this moment, .NET MAUI along with Blazor Hybrid does not officially support the desktop Linux platform. This has sparked discussions, though there has been no announcement on potential compatibility hereafter. This limitation leads teams to use Electron and Photino frameworks for projects that require Linux support. These allow to package Blazor applications for Windows and macOS, as well as Linux.
Such a deployment strategy helps maximize code reuse all across business logic, data access, and front-end. This allows it to meet offline and global web-access needs.
The section will explore the implementation of this dual-deployment approach, the stack decisions involved, and the best practices to ensure code maintainability for transitioning to microservices.
Blazor for desktop applications
Electron and Photino frameworks are the most popular for wrapping Blazor apps into a desktop environment. Both allow your web-based UI and C# logic to run on major operating systems.
| Electron features | – it combines Chromium and Node.js together, which allows to build native Blazor desktop applications – it’s supported by a robust ecosystem, with well-known success stories including Visual Studio Code, GitHub Desktop, and Slack – and allows larger applications by including an entire browser runtime each time |
| Photino features | – a more lightweight alternative that leverages the operating system’s built-in browser engine – utilizing WebKit-based controls on macOS and Linux, and a Chromium-based control on Windows – to render the Blazor desktop app – much smaller (often over 100 times) than an Electron-based application- and less widely adopted but supports cross-platform development for popular operating systems |

- External system interactions occur as needed for data transmission or retrieval.
Blazor cloud-based web services
The codebase can be shared across desktop distribution and an ASP.NET Core hosting environment:
- For accessibility by removing the need to install desktop clients, thus allowing users to log in from any internet-connected device
- More scalability by adding more servers or containers to handle large loads
- And security by centralizing new updates and patches, thereby eliminating the burden of distributing new executables
This dual deployment ensures customers get the best of both worlds: offline-friendly desktop solutions where needed and web-based, globally accessible apps for remote work.

Code reuse in both desktop and web-based development: our tips
Blazor app development’s advantage is extensive code reuse across both desktop and web-based platforms. But what are the best practices to maximize code reusability and pave the way for future business growth?
By following the guidelines described below, software developers can keep the most from their business logic, data models, and components:
Blazor hybrid apps leveraging code modularity
- Code encapsulation: break down your solution into modules (user management, billing, reporting), each owning its data and logic
- Public API: expose functionality through well-defined software interfaces to ensure clear boundaries and minimize code dependencies
Asynchronous communication
- Code modularity: code modules will communicate via channels (.NET Channels) or a bus-like mechanism, avoiding direct, brittle dependencies between them
- Non-blocking operations: offload tasks (data exports, file processing, email sending, or similar) to background (asynchronous) threads while preserving desired responsiveness
Planning microservices when running as a web-based service
- Identify needs for scalability: monitor modules that experience high loads or need most isolation
- Incremental extraction: move modules to microservices one at a time to minimize potential disruption
- Asynchronous communication: the transition from internal channels to message brokers is forthright with a distributed architecture
Real-world benefits: why go with hybrid?
With this dual-deployment strategy, the benefits go beyond simply “supporting more platforms”:
- Code reuse – you can centralize critical business logic, data models, and components once and share them across both desktop and web platforms
- Customer flexibility – customers might prefer traditional desktop environments for offline or sensitive data usage, while others need global, web-based access, and this approach helps satisfy both
