PeerWarp: Zero-Cloud P2P Direct File Transfer Platform
An open-source, production-grade file transfer platform engineered to move unlimited files and folders directly between browsers via encrypted WebRTC DataChannels, eliminating cloud storage intermediaries with direct-to-disk writing, on-the-fly compression, and local Wi-Fi radar.
The Double-Hop Problem: Why Traditional Cloud File Sharing Is Flawed
When developers, videographers, or remote teams need to send large payloads—such as 10 GB 4K video cuts, database backups, or source code trees—the default workflow is uploading to Google Drive, WeTransfer, or Dropbox. This model relies on an inefficient double-hop process: you must upload the entire file to a third-party server first, wait for the remote disk to stage it, and only then can your recipient download it.
This workflow wastes double the network bandwidth and time, stores sensitive enterprise assets unencrypted on corporate disks, and artificially throttles free tiers at 2 GB to push recurring subscriptions.
PeerWarp eliminates intermediate cloud storage entirely. It transforms modern web browsers into high-throughput peer-to-peer transfer nodes, creating direct encrypted data channels between devices so files move straight from device to device at wire speed.
WebRTC Transfer Architecture: Moving Data Without Intermediary Servers
At its architectural core, PeerWarp establishes direct peer-to-peer tunnels using W3C WebRTC DataChannels configured for ordered, reliable delivery over DTLS 1.3 and SCTP, guaranteeing end-to-end encryption.
The signaling server acts solely as a lightweight matchmaker during the initial handshake. Once client endpoints discover each other and complete ICE candidate exchange, the signaling server drops out of the loop and handles zero payload bytes:
Preventing Browser Crashes: Direct-to-Disk Streaming & On-The-Fly Compression
Traditional web apps crash when users attempt multi-gigabyte transfers because browsers stage the entire blob in heap memory before triggering a download. PeerWarp solves this browser memory ceiling through three key engineering decisions:
Local Wi-Fi Radar & Human-Gated Knock Security
To offer an AirDrop-style zero-configuration experience that works across all operating systems (Windows, macOS, Linux, Android, iOS), PeerWarp includes an edge-routed local radar:
Edge workers hash public egress IPs to detect devices connected to the same local router, populating nearby peers on the dashboard automatically without manual room sharing.
To prevent unsolicited file transfers and protect user privacy:
Enterprise Firewall Traversal & Hardened COTURN Relay
In corporate environments where symmetric NATs and carrier-grade firewalls block direct P2P hole punching, PeerWarp provides an encrypted fallback:
