They are currently experiencing many critical bugs found in old versions of their libraries (CVE-2026-13181, CVE-2026-13182, CVE-2026-13183, CVE-2026-13184, CVE-2026-13185, CVE-2026-13186,  CVE-2026-13190 etc) and refuse to provide free or inexpensive updates to users of the libraries that have stopped paying their annual fees (as we have moved on to other solutions). After negotiation and complaint they want $849 to get access to their urgent hotfixes for 1 year. Given the complexity of their tools and the way AI can now be used to find exploits, I can see this being a permanent outgoing. In 2020 they responded to a exploit in their code (CVE-2019-18935) by offering everyone a "complimentary" upgrade. What changed? Corporate greed and treating old paying customers with contempt, leaving older systems vulnerable to exploit. Shameful. Literally benefiting $$$ from old bugs.

They make all of their libraries SO difficult to use. Where you might have a simple property in someone else's control they bury in events. Their licensing system is a nightmare. I hate their tools with a passion. If it were up to me I would rip it all out and replace with some other UI library.

I've been using Telerik UI Controls for a number of years now and not only are the controls themselves extremely capable and feature rich, but their support is second to none. I have contacted them a number of times with tricky support questions and every time they give me a working solution within 24 hours. Their tech support people know their product inside out.

In our organization, we rely heavily on Progress Telerik's Kendo UI to solve important business challenges and improve our development processes. A key way we use Kendo UI is by creating a useful library on top of its framework. This library contains a variety of fast and strong components that help us quickly create powerful applications. With Kendo UI's many customizable components, our team can easily design dynamic interfaces, such as complex data grids, interactive charts, and user-friendly forms. By using these pre-made elements, we save a lot of time in development and ensure that our projects have a consistent look and feel, which helps us work faster and meet tight deadlines more easily. Kendo UI offers exceptional support across various versions of Angular, including the latest ones like Angular 17. This ensures that our development team can seamlessly integrate Kendo UI components into our Angular projects without worrying about compatibility issues. The reliable support provided by Kendo UI for all Angular versions further streamlines our development process, allowing us to focus more on building innovative solutions rather than troubleshooting technical hurdles. With Kendo UI's consistent updates and commitment to compatibility, we have the confidence to explore the latest Angular advancements while maintaining the efficiency and reliability of our applications.

Sono stato da progress ho comprato un mobile a tre ante, già montando i vari supporti di ritenzione il legno si iniziava rompere, finito di montarlo il tempo di metterlo in posizione si è rotto ed è caduto a pezzi, si trattava sicuramente di un pezzo difettoso, il personale gentilissimo subito a provveduto alla sostituzione del mobile

Vado da Progress da tantissimi anni..trovo sempre quello che mi occorre..i dipendenti di reparto sempre disponibili e preparati a consigliarti x il meglio..ottimo assortimento in tutti settori..5⭐⭐⭐⭐⭐meritate

The good: + Great quality Blazor, React, MVC and WebForm components + Outstanding performance of UI components + Amazing support The bad: - Document Processing for PDF component lacks many features compared to PDF components from other vendors (ie file attachments) and generated PDFs are GIGANTIC in size. We had to replace Telerik's PDF component with the PDF component from Syncfusion.

Works perfectly fine, great documentation, great controls, fast support.
