Built for Extreme Performance
We rebuilt the file transfer stack from scratch in Rust to achieve unprecedented speeds and unyielding security.
Zero-Cost Abstractions with Rust
Unlike tools bound by Garbage Collection pauses (Dart/Java/Node), xSend is a native compiled binary. Memory is statically managed at compile-time, allowing sustained gigabit throughputs without consuming excessive RAM or dropping network frames.
Native Memory Efficiency
Auto-Route Capability
If devices are on the exact same subnet, xSend utilizes ultra-fast raw TCP sockets. If isolated on different VLANs or entirely different internet connections, it seamlessly punches holes using QUIC. If blocked by symmetric firewalls, it relays securely via Cloudflare edges. It never fails to deliver.
Multi-Tier Connectivity
Symmetric E2E Encryption
Using an X25519 ephemeral handshake and ChaCha20-Poly1305 symmetric ciphers, your files are encrypted continuously during transit. Cloud servers, Internet Service Providers, and malicious listeners only see randomized noise.
