Why FLUX?

• Simple: open the app, choose a destination folder, and share.
• Fast: adaptive parallel transfer lanes tune themselves to the hardware.
• Private by default: files stay on your network instead of passing through a third-party cloud.
• Cross-platform: download a ready-to-run build for Windows, Linux, or macOS.
• Safe receiving: downloads are constrained to an explicit receiver folder, with traversal protection.
