We build tools that
respect developers
Rustini makes lightweight developer tools with Rust backends and native system integration. No Electron bloat, no cloud dependencies, no subscription fees.
Our first product is Markini — a fast, focused markdown viewer and editor that opens instantly and stays out of your way. Built with Tauri v2, it uses your system webview instead of bundling Chromium, resulting in a 2.5 MB installer.
We believe developer tools should be fast, private, and work offline. Every tool we build follows these principles.
Our principles
Native, not wrapped
We use system webviews and Rust backends — not bundled Chromium. Your OS already has a great rendering engine. We use it.
Offline by default
Every tool works without an internet connection. No accounts required to use the software. No telemetry, no tracking.
Pay once, own it
No subscriptions. No "free tier with limits". You buy a license, you own it. All future updates included.
Small and fast
If an installer is over 10 MB, something went wrong. If an app takes more than a second to open, something went wrong.
