FastSend P2P: Direct Encrypted File Transfer Without Cloud Limits or Subscriptions

Why Cloud Storage Is Failing Large File Transfers

Traditional file-sharing services force you to upload large files to their third-party servers before the recipient can download them. This doubles your transfer time and exposes confidential files to commercial cloud data scanning.

Direct WebRTC Device-to-Device Mesh

FastSend creates an encrypted, peer-to-peer data channel directly between sender and receiver using modern WebRTC standards. Files stream straight from your local RAM and disk to the recipient's device at full local network speed, without ever passing through a central server.

Features:

  • Zero File Size Caps: Send 500MB, 10GB, or 100GB files without hitting arbitrary limits.
  • Cross-Platform Compatibility: Works seamlessly across Windows, Mac, Linux, Android, and iOS browsers.
  • QR Code Pairing: Scan a pairing QR code on your phone to instantly beam photos or documents to your desktop.
100% OFFLINE • ZERO MONTHLY SUBSCRIPTIONS

Eliminate Costly Monthly SaaS Fees on Your Jobsites

Experience 100% offline inspection reports, AIA contract change orders, OSHA 300 logs, Manual J heat load sizers, and instant client invoicing. Pay once, keep forever on your hardware.
