With essential data-display features and minimal overhead, giving developers the performance they expect without unnecessary complexity.
What’s Included: Blazor Free Components
From inputs and layout elements to advanced data visualization – our open-source Blazor components are built to help .NET developers create modern web apps without wrestling with complex front-end stacks. Focus on building great C# applications with the controls and features you need.

“A mature UI component library remains essential to product quality, even in the era of AI-driven development. Infragistics’ decision to open-source Ignite UI for Blazor, including advanced layouts such as Tile Manager, will help teams build reliable UIs while reducing the cost of using AI to generate UI code starting today.”
