Engineered for speed, built for complete privacy.

DropBeam replaces slow cloud uploads, USB thumb drives, and messaging app file limits with direct socket streams.

Direct Local Socket Streams

Files travel directly across your local network via high-throughput TCP streams. Never routed through a remote server or public cloud storage.

  • Gigabit-capable transfer speeds
  • Zero bandwidth cost on cellular or metered home internet
  • Direct device-to-device TLS 1.3 encryption

Zero-Config mDNS Discovery

Devices discover each other on your local subnet automatically using mDNS and Bonjour. No pairing codes, PINs, or complex manual IP entry.

  • Instant local peer discovery
  • No central broker or rendezvous server needed

Tiny Native Footprint

Built natively with Swift and C# rather than heavy bundled browsers like Electron. Starts instantly and uses a fraction of your computer's memory.

  • ~10 MB disk footprint vs 200MB+ Electron apps
  • Under 35 MB idle memory usage

Cross-Platform Interoperability

Seamless file sharing between Apple macOS and Microsoft Windows without complex SMB shares, iTunes drivers, or flash drives.

  • Works seamlessly across macOS & Windows 10/11
  • Consistent drag-and-drop user experience

No. DropBeam establishes a direct peer-to-peer TCP connection over your local network between the sending device and receiving device. Your files never touch third-party servers, AWS buckets, or cloud services.
Yes. For automatic mDNS discovery and local transfer speeds, both devices must be connected to the same local area network (LAN / Wi-Fi). If you need to send to a mobile phone, they can join the same Wi-Fi or personal hotspot.
Absolutely. DropBeam is purpose-built to break the cross-platform barrier. You can send files freely between macOS and Windows 10/11 with zero friction.
There are no artificial file size limits. Whether you are sending a 10 KB text file or a 50 GB 4K video archive, DropBeam streams the data chunk-by-chunk directly between devices without buffering everything into RAM.
No. DropBeam requires zero accounts, zero registrations, and zero personal credentials. You open the app, and you are ready to transfer immediately.
