Per-developer licenses to design and build commercial apps.
Build real-time web apps,
written entirely in .NET.
Wisej.NET is the full-stack framework for .NET developers. Design the UI, write the logic, and keep the browser and server perfectly in sync — all in C# or VB.NET, inside Visual Studio. No JavaScript glue, no REST plumbing.
Full feature set · 30-day trial · No credit card required
Drag, drop and arrange in the Visual Studio designer.
New release
Wisej.NET 4.1 is here — accessible, test-ready, richer visuals.
Accessibility comes first in 4.1: comprehensive support with ARIA roles, full keyboard navigation and screen-reader compatibility, backed by improved Playwright compatibility for reliable end-to-end testing. Alongside that come a new Mermaid diagram extension, Lucide Icons, a Dashboard control and ChartJS 4 for richer data visuals, plus refreshed visuals and a host of further refinements.
One framework
Everything a web app needs, on the stack you already know
Stop stitching together a front-end framework, an API layer, and a real-time channel. Wisej.NET gives you the whole stack as one .NET application.
Write the whole app in C# or VB.NET
UI, business logic, and client–server communication live in one language and one project. Reuse your models, your libraries, and your team's existing skills from day one — the learning curve is essentially flat.
Pixel-perfect visual designer
Drag, drop, and arrange complex screens directly in Visual Studio. What you design is what ships to the browser.
Real-time by default
A live WebSocket bridge keeps browser and server in sync automatically. Push updates to any client without writing transport code.
100+ controls out of the box
Grids, charts, editors, layouts, dialogs and more — a complete control set, ready to use, with no third-party shopping list.
Responsive & fully themeable
Breakpoints, grid layouts, anchoring and auto-sizing adapt to any screen. Style everything with a JSON theme or the visual Theme Builder.
Open & integrated
Wrap any JavaScript widget and drive it from C#. Wisej.NET wires it to the server for you — free of routes, unsafe APIs and boilerplate.
How it works
Your code stays on .NET. The UI runs in the browser.
- 01
Design in Visual Studio
Build pages and components visually or in code. Event handlers are ordinary C# methods that run on the server.
- 02
Wisej syncs the client
The framework renders your UI in the browser and maintains a live link, sending only the changes — over WebSocket, automatically.
- 03
Ship anywhere
Deploy as a web app, or package the same project as a native desktop or mobile app with Wisej.NET Hybrid.
Wisej.NET Hybrid
One codebase. Every platform.
The same Wisej.NET project that powers your web app can ship as a true native application — with access to the device's camera, files, notifications and sensors through a clean C# API.
- Native desktop apps for Windows and macOS
- iOS and Android apps from the same source
- Installable PWAs for offline-capable web
- Shared business logic across every target
Deploy your way
Cloud, on-premise, or self-hosted — your call
