ai generates weird xaml sometimes.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Describe the UI or component you want and let the built-in assistant generate the corresponding XAML and C#, then adjust the result by hand.
Write and edit C# and XAML directly in the browser with immediate feedback, so you are never limited to what a visual designer exposes.
Drag, drop, and arrange controls in a WYSIWYG surface to lay out windows and views, then jump into code for the details.
Take a project from prototype to a published Web or Desktop build, and open the same project in Visual Studio when you want a local toolchain.
No install and no vendor lock-in: the same project files move with you between the browser environment and desktop tooling.
XAML.io is an online workspace for building .NET applications without a local IDE installation. It brings three ways of working into a single project: an AI assistant that generates XAML and C# from descriptions, a code editor for writing XAML and C# directly, and a visual drag-and-drop designer for laying out interfaces. Because all three operate on the same project, you can sketch a screen visually, refine it in code, and use AI to fill in repetitive markup.
The platform is built around XAML, the markup language used across WPF, MAUI, and related .NET UI frameworks, and it sits in the lineage of tools like OpenSilver that keep XAML-based development alive on the web. That makes it useful for developers who want to prototype a .NET interface quickly, port an existing XAML idea into the browser, or explore UI ideas before committing to a full desktop toolchain.
Projects built on XAML.io can be published to Web and Desktop, and — importantly — the same project can be opened in Visual Studio. The site markets itself as free, with no setup and no lock-in, so it works as a low-friction starting point rather than a walled garden. XAML.io is an independent product and is not affiliated with Microsoft; framework names such as XAML, WPF, .NET, and Visual Studio are referenced only to describe compatibility. Verify current publishing targets and feature details on the site, as a browser-based tool of this kind evolves quickly.
Rapidly mock up a .NET interface in the visual designer and let AI fill in the XAML, then publish a Web or Desktop build to validate the idea.
Sketch a screen visually, then switch to direct C# and XAML editing to fine-tune bindings, styles, and events without leaving the browser.
Use the AI assistant to generate boilerplate XAML for controls and layouts on a machine without a full toolchain, then open the project in Visual Studio later.
Convert a concept into a browser-hosted .NET app and hand the project off to a team that works in Visual Studio.
