Your code. Your infrastructure. No lock-in.
Radzen generates standard Blazor apps you own outright — build, deploy, and maintain them on your terms.
Your code
Radzen generates standard, human-readable C# and Razor that lives in your repository. Build it with free tools — no proprietary runtime, no black box to reverse-engineer.
Your infrastructure
Deploy anywhere .NET runs — your cloud, on-premises, or air-gapped. Your databases and secure data sources never have to be publicly exposed.
No lock-in
No per-app runtime fees and nothing to rip out if you leave. The app you ship keeps building and running with or without Radzen.
Build with the AI agent of your choice
Radzen Blazor Studio is the open home for AI coding agents — no proprietary agent to learn, and the code stays yours.
Your All-in-One Solution for Blazor Application Development
Everything you need to build, ship, and maintain Blazor apps — data, design, development, and deployment in one place.
How is Radzen Better?
One environment for visual design, code, and AI agents — backed by the open-source component library and the C# you already know.
