A lightweight desktop overlay application for displaying browser sources on top of other windows, similar to OBS browser sources but for your desktop.
- 🌐 Browser Source Overlays: Display any web content as transparent overlays
- 🎯 Click-Through Mode: Overlays become transparent to mouse clicks when locked
- ✏️ Edit Mode: Toggle between locked overlay mode and movable/resizable edit mode
- 📝 Source Management: Add, rename, delete, and reorder browser sources
- 💾 Persistent Configuration: Automatically saves window positions and source URLs
- 🎮 Global Hotkeys: Control overlays from any application
FloatView supports any web-based content that works in modern browsers, including:
- 📺 Streaming overlays (alerts, chat widgets, donation goals)
- 🎮 OBS-compatible browser sources
- 💬 Discord talking heads (like Reactive by Fuji)
- 📊 Dashboard widgets and monitoring tools
- 🌐 Any web application or interactive content
If it works in OBS Studio's browser source, it will work in FloatView!

https://URLs instead ofhttp://
