Design Once. Run Everywhere. Fast.

With DevExpress eXpressApp Framework (XAF) you can quickly create functional and highly responsive apps that meet the needs of your ever changing enterprise and target both Windows, the Web and Mobile.

XAF uses a hybrid rapid software development flow - a flow that lies somewhere between a traditional 'all manual' development methodology and a totally 'codeless' (low-code) approach.

Documentation: The XAF Advantage | XAF App Architecture

I stumbled across DevExpress and tried out the XAF framework. To say I was blown away would be an understatement! I was simply amazed at the ability to define my data model and have the basic UI for CRUD created automatically. With every new feature I discovered, I was more amazed. David Landry

Fastest App UI Builder for EF Core

From C# Entity to Powerful Web, Desktop, and Mobile UI Forms in Minutes

XAF allows you to build feature-rich Office-like LOB apps that target .NET 6+ using Windows Forms and ASP.NET Core Blazor UI. With its integrated wizard, you'll create Web/REST API Services in minutes. Entity Framework Core for data access allows you to consume data from popular relational database management systems (RDBMS) including Microsoft SQL Server, PostgreSQL, Oracle, MySql, SQLite, Firebird, etc. You can get started quickly with EF Core community (third-party) modules and ready-to-use built-in XAF modules such as Audit Trail, Validation, and Security System.

XAF also helps developers create multi-tenant or SaaS-ready apps with multiple databases using a few declarative lines of code instead of writing hundreds of lines of code. The Multi-Tenancy module automatically creates a host and tenant databases at runtime. You can also authenticate with an email or OAuth2 account (like Microsoft Entra ID or Google) - the domain automatically resolves the tenant and its storage.

Model-Driven UI. Flexibility.

Easy-to-use and highly customizable form layout.

Generate your data model of any complexity from an existing database using XAF wizards, or define the model manually in code or using the visual scheme designer. XAF automatically generates a final and fully customizable UI based on your data model. This includes everything you need: various data forms, menus and app navigation, reporting, charting, analytics – powered by award-winning DevExpress controls and libraries. When user requirements or the context of use change, the data model changes accordingly and so does the supporting UI.

Thanks to its rich set of runtime UI customization options (for developers and end-users alike), XAF's Blazor and WinForms UI allows you to address changes in business requirements without the need for redeployment. If you've used Microsoft Office apps, you already know that runtime UI customization (especially in your web browser) can be a time saver.

Straightforward Interoperability API

Connect Your XAF App to any External Solution

XAF's Solution Wizard includes a "1-Click" solution to create ASP.NET Core Web/HTTP API services (via OData and Swagger/OpenAPI). This service allows developers to reuse XAF application data, logic, and modules (like CRUD, security authorization and authentication) within non-XAF apps. You can use OAuth2, JWT or custom strategies for authentication and tools like Postman or Swagger for API testing.

XAF-powered WinForms apps can also connect to a middle-tier application server for optimum data security. With this additional layer of protection, desktop UI clients cannot access database connection information or modify database tables directly. XAF’s built-in security system also filters out secured server data based on permissions granted to users.

Reviews from Your Peers

 

Piero Giorgi   ★★★★★

Started using DevExpress as an experiment in 2008. Now, every application I write is ALWAYS using DevExpress UI controls and services. I have been able to convince every IT manager I met to get the DevExpress suite, both for the exceptional quality of the controls, and the really quick comeback from support, every time it's needed.

Mustafa Çağrı ALTINDAL   ★★★★★

In general, I met the DevExpress Application Framework (XAF) in 2016. Since the day I met, I am a person who makes the best use of functionality and time savings in software production and programming. Currently, we are still using 100% DevExpress modules in our software. It's great to be supported between 4 and 10 hours in the comeback. Again, thank you to the DevExpress team.

Christian Cigler     ★★★★★

For over 5 years now we have been using DevExpress components and in particular XAF. The decision for XAF was made immediately after a test project, because the time for implementing customer requirements is radically reduced. Is everything always ideal? - No, but the exceptional support always helps quickly and reliably. I have never experienced anything like this with other manufacturers until now. If someone wants to develop professional applications for their customers quickly and efficiently, there is no way around XAF.

 

Roman Shelomanov   ★★★★★

Quality, Speed, and Cost - XAF gives us the ability to conduct high quality, rapid and thus inexpensive development of modern, good-looking business apps.

High Quality - DevExpress is considered to be the gold standard in the development of graphical UI. Using XAF is like hiring a team of professional developers, analysts and graphical designers to design our program. It also gives us testers for free, because XAF ships with a built-in functional testing framework - Easy Test that helps us to automatically check the quality of the programs we created.

Andrei Iorga     ★★★★★

This just might be the best development suite in the world. It has great components and tools, by far the best RAD framework available anywhere (XAF), and the best support team anywhere. The documentation is great and you simply cannot go wrong with DevExpress.

I highly recommend it to everyone, especially to anyone that needs a mature RAD framework with great support.

Marc Greiner   ★★★★★

DevExpress XAF is an elegant answer to low-code and RAD, without limits. I am using the XAF framework intensively, and each day, I feel like sending to the DevExpress developers the caviar and the Champagne that they deserve for having build such a marvelous and unique application development tool.
