What Are DevExpress and Syncfusion?
If you are building line-of-business applications on .NET, you have almost certainly narrowed your UI component search down to two names: DevExpress and Syncfusion. Both ship hundreds of controls for ASP.NET MVC, ASP.NET Core, Blazor, WinForms, WPF, .NET MAUI, and JavaScript frameworks, yet they differ significantly in architecture, API philosophy, licensing, and price. This page gives you something feature-matrix PDFs cannot: live, side-by-side demos running identical data so you can judge rendering quality, responsiveness, and developer experience for yourself.
DevExpress
Founded in 1998 and headquartered in the United States, DevExpress is one of the longest-standing .NET component vendors. Their ASP.NET MVC extensions use a server-side rendering model: controls execute on the server, generate HTML and JavaScript callbacks, and handle state through encrypted ViewState-style payloads. This approach delivers pixel-perfect output and deep server-side event handling but ties your front end tightly to the .NET pipeline.
- 700+ UI controls across all .NET platforms
- Server-rendered GridView with built-in callbacks
- Integrated reporting engine (XtraReports)
- Mature documentation and large community
- Premium pricing — starts around $1,500/developer/year
Syncfusion
Founded in 2001 and based in the United States with a large development centre in India, Syncfusion takes a client-side-first approach. Their Essential JS 2 (EJ2) library renders controls entirely in the browser using JavaScript, and provides Razor tag helpers and HTML helpers as thin server-side wrappers. The result is a lighter server footprint and a more modern, SPA-friendly architecture, though it shifts more responsibility to the client.
- 1,800+ UI controls (includes JS, Blazor, MAUI, Flutter)
- Client-rendered EJ2 Grid with JSON data binding
- Built-in PDF, Excel, Word, and PowerPoint libraries
- Free Community License for small businesses (< $1M revenue)
- Team license starts around $995/developer/year
Key Differences at a Glance
| Criteria | DevExpress | Syncfusion |
|---|---|---|
| Rendering Model | Server-side (callbacks) | Client-side (JavaScript) |
| Grid Architecture | GridView with encrypted state | EJ2 Grid with JSON binding |
| ASP.NET MVC Support | Dedicated MVC Extensions | HTML Helpers wrapping EJ2 |
| Blazor | Native Blazor components | Native Blazor components |
| Free Tier | 30-day trial only | Community License available |
| Reporting | XtraReports (banded designer) | Bold Reports / PDF library |
| Learning Curve | Steeper — proprietary API patterns | Moderate — closer to standard HTML/JS |
| Best For | Complex enterprise apps with heavy server logic | Modern web apps, startups, budget-conscious teams |
Why a Live Comparison Matters
Feature checklists tell you both grids support filtering, paging, and editing. What they cannot tell you is how each grid feels in practice: how fast a 10,000-row grid scrolls, how intuitive the inline editing UX is, or how many kilobytes of JavaScript are shipped to the browser. The demos below load the same invoice dataset into both a DevExpress GridView and a Syncfusion EJ2 Grid so you can answer those questions by clicking, sorting, and editing yourself.
We are not affiliated with either vendor. We have delivered production applications with both toolkits for over a decade and built this resource to help development teams make an informed decision without having to install two trial packages and wire up sample projects.
