Advanced Borderless Window Manager for Windows
If OmniBorder has saved you time or made your gaming/work sessions better, please consider supporting its development! You can compile it yourself for free, but your support keeps this project alive and updated.
OmniBorder is a professional Windows utility designed for gamers and power users who demand seamless multi-monitor experiences. It forces external applications and games into true Borderless Windowed Mode, solving common pain points that native Windows settings fail to address.
- Focus Loss Prevention: Games and applications lose focus when alt-tabbing or switching monitors. OmniBorder aggressively retains focus using advanced Win32 APIs.
- Multi-Monitor Persistence: Assign specific applications to dedicated monitors and remember their positions across sessions.
- Rebel Taskbar Hiding: Removes stubborn taskbar icons from Electron/Chromium-based applications (Discord, Chrome, VS Code) that ignore standard borderless modes.
- Modern UI Stripping: Uses DWM (Desktop Window Manager) to hide custom title bars and frames in modern UWP/XAML applications.
- Native Dark Mode: Full system-wide dark theme support with automatic detection and manual override.
Whether you're setting up a sim racing rig, a flight simulator cockpit, or simply want cleaner multi-monitor productivity, OmniBorder delivers professional-grade window management.
