Coming Soon
Private chat and file sharing between your own computers — end-to-end encrypted, device to device, with no cloud, no servers, no account, and no tracking.
A small window that lives in your system tray or menu bar — open it, pick a device, and talk to it like any messenger. Except nothing ever leaves your machines.
Concept renders — the shipping UI may differ in the details.
No account creation, no sign-in, no configuration files. Two machines can be talking in under a minute.
Devices on your network find each other by name automatically. Pick one, approve the request on the other side, and set a one-time password to seal the trust.
Send messages between your machines with delivery confirmations. History stays encrypted on each device, and offline messages arrive when the device comes back.
Drag any file into the conversation — large ones included. It lands on the other machine organized by sender, one click from opening.
Most "sync" tools quietly route your files through someone else's servers. ThruPlex doesn't. Your devices connect straight to each other over your network — or over your own VPN when you're apart.
Everything happens on your machines and your network. Nothing is uploaded, hosted, or held by anyone else.
Your devices connect directly over your network. There are no relay servers and no cloud storage — your data never touches anyone else's computer.
Every message and file is protected with modern cryptography — X25519 key exchange and authenticated encryption, built on the trusted libsodium library.
New devices join only when you say so: you approve the request and set a one-time password on the receiving device. Wrong guesses get locked out.
Devices on the same network discover each other automatically and appear by name. On different networks? Connect by address — VPNs like Tailscale work great.
A full conversation per device, with delivery acknowledgements. History is encrypted at rest, and messages sent while a device is offline arrive when it reconnects.
Send files right in the conversation — large files included. Incoming files are saved neatly per sender, one click away from opening.
A lightweight native app that lives in the Windows system tray and the macOS menu bar. One click to open, invisible when you don't need it.
Nothing to sign up for and nothing phoning home. Install it, pair your devices, and everything stays between them.
Native apps, built for each platform.
Windows 11 · 64-bit
System tray app with a familiar installer
macOS 13 Ventura and later · Apple Silicon
