Ignite UI Releases 50+ Powerful Open-Source Components

Here at Infragistics, we are marking a major milestone for Ignite UI and app development in general.

The big change? We are going open source!

As of now, as part of our UI toolset, we are empowering the open-source community by providing a set of 50+ open-source components under the MIT license across Angular, React, Blazor, and Web Components. This is a major expansion of our mission: to empower every developer, everywhere, with modern, feature-packed, and future-proofed tools for building high-performance web applications for every scenario.

Why This Matters?

For years, the Ignite UI team has listened to developers who want flexibility, transparency and collaborative innovation. Open-sourcing core components is our commitment to comply with that vision. By sharing a robust component library across the most popular web frameworks out there, we’re empowering developers to:

• Quickly build consistent UIs across frameworks.
• Customize, extend, and contribute to publicly visible code.
• Grow with us, moving from open source into the premium feature set as their needs evolve.

We’ve been in the developer tools market for more than 35 years, and our UI components have powered applications across every industry. Open source allows us to give more back our growing community. With this transition, we aim to equip everyone ready to innovate, build beautiful user experiences, and provide custom solutions. Solutions that integrate seamlessly into enterprise environments, reduce development overhead, and ensure long-term stability.

Prior to this move, many of our components were already free to use. Just not formally listed as such in our licensing model. With the decision to introduce open-source controls:

• That informal flexibility becomes an official commitment.
• Our open-source components gain the visibility and contribution pathways of GitHub.
• Developers now have the freedom to modify and extend components as deeply as they need.

All of this solidifies our long-term dedication to innovation, transparency, and developer empowerment.

Free to Use, Free to Build With. No Commercial License Required

With this update, developers can:

• Use our open-source components freely in production: MIT license.
• Use them however they choose: Customize, fork, inspect, or extend them. We are ensuring full freedom.
• Access the same quality Ignite UI is known for: The open-source components are the same well-engineered, battle-tested components our customers have used for years.

All of the 50+ open-source components are now MIT-licensed, giving developers worldwide maximum flexibility. These include Grid Lite, Accordion, Avatar, Badge, Banner, Button, Button Group, Calendar, Card, Carousel, Chat, Checkbox, Chip, Circular Progress, Combo, Date Picker, Drop Down, Dialog, Input, List, Tile Manager, Toolbar, Snackbar, Stepper, and many more.

What Stays Premium: Advanced Controls for Enterprise Apps

While the bulk of our UI library is now open source, a select set of our most advanced components remains premium. These include:

You can still test every premium component locally, access all features, and fully evaluate them in your environment. They even run in production for testing purposes, but with watermarking. A commercial license is only required when you’re ready to deploy them in customer-facing, production applications.

This dual approach ensures that every developer gets a powerful foundation for free, while teams building high-performance, enterprise-grade solutions retain access to advanced, professionally supported components.

All Premium components are marked in the header of their topics with: 

What Does This Mean for Existing Customers

If you’re already using Ignite UI, nothing changes about your current experience:

• You keep using all the components exactly as before.
• Your premium components remain fully supported and maintained.
• You now gain access to a larger, open-source ecosystem driving faster improvements and new features.

Open source adds value to your subscription. It doesn’t replace or diminish it.

Here Are Some of the Key Ignite UI Open-Source Components

Grid Lite – lightweight control for handling data-driven applications. It provides essential data-display capabilities with minimal overhead and the performance users expect. Key features include column filtering, hiding, resizing, and sorting, row virtualization, accessibility support, theming and styling options, and column data type configurations.

Combobox – a drop-down list, providing editable functionalities and filtering capabilities, grouping, and adding custom values. It can be used as an alternative to the HTML select tag and offers several out-of-the-box features, such as data binding, filtering, and grouping.

Tree – this component lets you display information in a tree view, showing items with parent-child relationships. You can use it with real data or create a static tree manually. The Tree control provides load-on-demand capabilities, item activation, bi-state and tri-state cascading selection of items through built-in checkboxes, etc.

Stepper – it delivers a wizard-like workflow and multiple features like step validation, styling, orientation, and keyboard navigation.

Wrap Up…

Over the years, we’ve consistently invested in advancing Ignite UI across hundreds of GitHub commits, major framework updates, and the constantly shifting web ecosystem. Our mission remains unchanged: to deliver robust, modern UI solutions that developers can rely on.

By open-sourcing more than 50 of our core components across Angular, React, Blazor, and Web Components, we’re taking that commitment to the next level. This is just the beginning. We will continue to expand and refine both our open-source and premium controls so that every developer, from startup innovators to large enterprise teams, can build exceptional digital experiences with the right tools.
