Agentic Development, Powered by Uno Platform
Harness AI Agents and MCP servers that understand your code and context and always keeps you in control.
Hot Design Agent
- Design with Al tooling that builds your UI while the app is running.
Human-In-The-Loop
- Stay in full control by approving Al actions at every step right from your IDE or CLI environment.
- Build on a solid foundation with Uno Platform’s proven architecture and best practices for easy, maintainable code.
App MCP
- Allow agents to control the running app using pointer / keyboard interactions and visual tree queries.
- Enable AI agents from Visual Studio, VS Code, Claude Code, GitHub Copilot CLI, Codex, and more.
MCP
- Leverage semantic understanding and benefit from an Al that grasps your intent and delivers precise,
context-aware answers. - Get instant, accurate guidance grounded in official Uno Platform documentation right from your IDE.
