Uno Platform 6.5 Released With AI Agent Support, Unicode Text, and Studio Improvements

The Uno Platform has released version 6.5, its latest update, bringing a range of improvements to both its Studio tooling and the core cross-platform framework. This release resolves over 450 community and customer issues, making it a significant update for developers.

AI Agent Support and Antigravity Integration

One of the key additions in this release is support for Google’s Antigravity, an agent-first development environment built on top of VS Code. Through integration with the Uno Platform App MCP server, AI agents working inside Antigravity can now interact with a running Uno application at runtime. An agent can inspect the visual tree, take screenshots, simulate user input, and verify real interface behavior rather than relying on static code analysis.

Studio Improvements and Hot Design Updates

On the Studio side, Hot Design, Uno’s live visual design tool, has received several usability improvements. It now launches automatically when a new project is run for the first time, removing extra setup steps. A new introductory experience guides users through the three available modes: Agent, Design, and Interactive. Additionally, a new scope selector has been added, allowing developers to navigate directly to any UserControl or template visible on the current screen.

Unicode Support and Platform-Level Improvements

Version 6.5 adds Unicode support to the TextBox control, enabling non-Latin scripts, including Arabic, Mandarin, and Hindi, to render with correct caret positioning, text selection, and keyboard navigation. Furthermore, WebView2 on WebAssembly has been improved, with more reliable loading of locally bundled web assets. Drag-and-drop on WebAssembly using the Skia renderer has been expanded to support file drops from external applications.

Conclusion and Call to Action

In conclusion, the Uno Platform 6.5 release brings significant improvements to the framework and its tooling. With AI agent support, Unicode text, and Studio improvements, developers can now create more powerful and user-friendly applications.
