Synapse on your desktop
A native app with full local file access, offline mode, and instant startup. The same powerful editor — without the browser.
Built for your workflow
Everything you get in the browser, plus native capabilities that make development faster.
Native performance
Direct system access with hardware-accelerated rendering. No browser overhead.
Offline-ready
Work on themes without an internet connection. Changes sync when you reconnect.
Auto updates
New versions install silently in the background. Always on the latest release.
Secure by default
Sandboxed processes, code signing, and encrypted local storage out of the box.
Local file access
Open theme folders directly from your filesystem. Drag-and-drop project import.
System integration
Native notifications, system tray, keyboard shortcuts, and deep OS integration.
