Zenthra
A high-performance, Rust-based UI framework for building native desktop applications with zero-runtime overhead and 4ms input latency.
Visual Showcase
Explore screenshots of high-performance applications built entirely on Zenthra's native GPU-accelerated graphics stack.
Zenthree IDE & Code Editor
GPU-accelerated code editing with Tree-sitter syntax highlighting, PTY terminal, and frosted glass UI.
Zenthra View
A native image viewer built using Zenthra's dual-pass frosted glass textures and GPU paint canvas.
ZenFile File Manager
Lightweight, hardware-accelerated directory navigation with customizable frosted glass columns.
Image Viewport Controls
Precision floating-point zoom, pan, and rotate controls rendering directly on metal-level GPU buffers.
Dynamic Thumbnail Matrix
Asynchronous multi-threaded directory scanning maintaining solid 60 FPS viewport scrolling.
Native Modal Architecture
Sub-pixel vector fonts shaped by Cosmic Text combined with Taffy flexbox layout logic.
Simple by design.
Zenthra's API is intentionally minimal. You describe your interface as composable widgets — the framework handles the rest. No lifecycle hooks, no re-render cycles, no magic.
The entire widget tree compiles to a flat sequence of native draw calls at build time. What ships is a tiny binary with zero interpreter overhead.
What makes it different.
Zenthra is opinionated about the things that matter and silent about everything else.
Zero Runtime
No virtual DOM, no garbage collector pauses. Zenthra compiles your UI to direct native calls.
4ms Latency
Input-to-pixel latency measured at 4ms on target hardware. Feels instant because it is.
Rust-Powered
Written in Rust for memory safety and predictable performance. No undefined behavior, ever.
Native Widgets
Every widget maps 1:1 to a platform-native control. Looks right on Linux, macOS, and Windows.
Composable API
Build complex layouts by composing simple, orthogonal widgets. No magic, no hidden state.
Cross-Platform
One codebase. Ship to Linux, macOS, and Windows with native look and feel on each.
