Their Xamarin UI tools are great Their Xamarin UI tools are great, and the free Community license is indispensable for small developers like myself. I've contacted their support group a few times, either with questions or bugs, and their responses are timely and helpful.

Not so good Other companies, such as Telerik and DevExpress, offer superior products. While they may have fewer components, they are well-tested. With Syncfusion, we've encountered numerous bugs in their controls, resulting in significant time wasted on ticket submissions. The support provided by Syncfusion is subpar; they often take months to address issues and seem indifferent to user feedback. Their proposed solutions frequently fail to address the root problem. Additionally, feature requests remain in evaluation for years without any meaningful response to our requirements. The design of the Blazor components is particularly poor. Given the recent price increase, it's advisable to consider alternatives in the market.

Untested controls I have been using some of their controls for Xamarin Forms for 5+ years now. My honest opinion is that their controls are highly untested. So if you are aiming for a more complex use than the shown in guide, you are going to find out some important bugs. I can say I found problems with almost all of controls I used. Some problems are just easy to solve (elements of style customization being ignored). Some other are just making the whole control unusable. For instance, SfChat has an obligatory behaviour of starting the listView on the first message and automatically scroll till last one. Super cool when you have 20 messages. UNUSABLE in real cases where you have 1500 messages as you would just stay staring at the screen scrolling by inself for 30 seconds without even being able to interact with the control. If you just want the plain control without any type of customization, it definitely saves you some implementation time.

Excellent Support From other reviews, they seem hit-and-miss, but my experience is excellent. One query I had on the forums was down to the way I was using a control, and another query is a genuine bug report. They got back to me within 24h and are letting me know the bugfix progress. I can't ask for more - especially as I'm only on the community licence.

167% price increase When i did know this in front i never started with Syncfusion. We started with 3 licenses in 2020 for $1200,- 2021 $1295,- 2022 $1495, 2023 $1495,- and now they say they changed their license structure to make it more suitable for their customers and the normal price is now $4750,- and we can get a super discount of 15% and will pay $4000,- an increase of 2500/1495 = 167% As that is a normal way of doing Business with Syncfusion I want warn all who are considering to start using Synfusion
