What People are Saying About Our Products
5/5You get a comprehensive set of UI components that are well-built, consistent, and reliable for real-world applications. The one thing I like the most is the performance of data heavy components like data grids and charts. You rarely get that in other component libraries or at least not on the same level. I really like the new set of open source components for Angular and React. They’re ideal for smaller projects and applications, allowing teams to build without adding extra licensing costs.
5/5We’ve been using Ignite UI for Angular for close to five years, primarily for the grid and its advanced features. The grid is powerful, flexible, and well suited for data-heavy scenarios. I also appreciate the recent move to release more components as open source, which makes the library more accessible, transparent, and easier to adopt across teams and projects./p>
5/5The grid is very powerful: fast rendering, excellent filtering, sorting, grouping, and looks clean out of the box. Myteam really appreciates how feature-rich it is.
5/5The Grid handles huge datasets with smooth scrolling and includes features like filtering, grouping, inline editing, and Excel export right out of the box.
5/5The drag-and-drop components speed up UI creation dramatically, while the generated code is clean and portable. I can easily switch frameworks. Also, I love that there’s no vendor lock-in.
5/5During our research we found Reveal and they promised fast deployment, extreme security measures, and significantly lower price tag. It turned out they were right. It took about a month to deploy and the cost saving was astronomical.
5/5The reusable components are framework-agnostic, which means I can design once and use them across Angular, React, Blazor or Web Components. This makes our development stack more flexible, especially when projects have different requirements.
5/5The Pivot Grid is brilliant. I just drop it onto the canvas, bind it to a data source, and App Builder automatically creates a pivot view for me.
5/5The library of over 65 reusable UI controls and prebuilt themes means you spend less time styling and more time designing flows and interactions. Built-in data binding, Master-Detail views and GitHub integration make it robust as well
Frequently Asked Questions
What are open-source Web Components?
Open-source Web Components are reusable UI building blocks built using web standards such as Custom Elements, Shadow DOM, and HTML templates. They work in any environment that supports Web Component standards - including Angular, React, Blazor, and plain JavaScript projects - without requiring a framework-specific integration layer, enabling developers to build consistent UIs without being tied to one specific technology.
Are Ignite UI Web Components really free?
Yes. The open-source Web Components from Ignite UI are fully free, released under the permissive MIT license.
Can I use these components in production?
Yes. The free Web Components controls derive from a mature and well-established UI component ecosystem used by enterprise teams worldwide. This means that all the open-source controls for Web Components are suitable for production-grade apps. You can explore different Web Components samples and see how they work.
How do Ignite UI for Web Components compare to Web Awesome or FAST?
Ignite UI for Web Components is not limited to OSS controls only. There's a broader range of components, including advanced data grids, charts, and 100+ other controls. Unlike most standalone Web Component libraries, Ignite UI's open-source controls are part of a broader commercial UI ecosystem. This means a direct upgrade path to enterprise-grade components - advanced data grids, charts, and 100+ additional controls - without switching libraries or re-learning architectural patterns. The Ignite UI AI toolchain (Skills + MCP Server) also integrates directly with these components, something no other OSS Web Component library currently offers.
Are the components actively maintained?
Yes. This is not a hobby OSS project that will be abandoned. All the open-source Web Components controls are maintained by the Infragistics engineering team, with active development and updates delivered through the public GitHub repository.
Can I upgrade later to the full Ignite UI platform?
Yes. The open-source components follow the same architectural principles as the broader Ignite UI ecosystem, making it easy for teams to expand their UI capabilities if enterprise requirements evolve. For instance, you can start with Grid Lite for essential needs and then upgrade to the full-featured Data Grid if your app scales and grows in complexity. This ensures minimal refactoring and a smooth transition to advanced, enterprise-grade capabilities.
