Get Started
Our Story
Built by developers
who felt the gap.
For years, we've watched the WinForms community feel sidelined as the world of modern design moved on.
As the creator of the Bunifu Framework and a multi-year Microsoft MVP, our founder built this ecosystem because we believe you shouldn't have to choose between the reliability of .NET and the beauty of modern software.
Developer Experience
What you see.
Is what you get.
Kimtools Designer is a WYSIWYG
powerhouse for WinForms that replaces static properties with a semantic theme engine
and integrated color tokens.
It bridges the gap between design and code with a VsCode-style
markup editor for real-time HTML/SVG editing, an integrated icon search, it allows you to visually compose
modern, production-ready
interfaces with instant, live feedback directly on the design surface.
