What People are Saying About Our Products
You 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.
We’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>
The 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.
