5-star rating 5/5

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.

5-star rating 5/5

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>

5-star rating 5/5

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.

5-star rating 5/5

The Grid handles huge datasets with smooth scrolling and includes features like filtering, grouping, inline editing, and Excel export right out of the box.

5-star rating 5/5

The 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-star rating 5/5

During 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-star rating 5/5

The 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-star rating 5/5

The 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-star rating 5/5

The 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
