The problem

LAN sync shouldn't require a manual.

Most file sync tools are either too complex or send your files to the cloud. CoveSync is neither.

The usual experience

  • ✗ Configure device IDs manually
  • ✗ Edit config files to share a folder
  • ✗ Debug firewall rules when it stops working
  • ✗ Cloud sync sends your files to a stranger's server
  • ✗ Monthly subscription for something that should be simple

CoveSync

  • ✓ Pair devices with a 6-digit PIN
  • ✓ Share a folder in two clicks
  • ✓ Firewall rules configured automatically on supported systems
  • ✓ Files never leave your network
  • ✓ One payment. Yours forever.
Features

Everything you need. Nothing you don't.

Built for people who want reliable file sync without becoming a sysadmin.

🔒

Stays on your network

Files sync directly between your devices. Nothing touches the cloud. No third party ever sees your data.

⚡

PIN pairing

Add a new device in seconds. No accounts, no emails, no certificates to manage. Just a 6-digit code.

🔄

Always syncing

Runs as a background service on Windows and macOS. Starts at boot, syncs automatically whenever devices are on the same network.

🖥️

Cross-platform

Windows, macOS, Linux, and Android. Mix and match — your Mac and your Windows PC sync seamlessly. Android requires at least one PC on the same network.

🛡️

Encrypted in transit

All traffic between devices is encrypted with mutual TLS. No one on your network can intercept your files.

🌐

Browser UI

Manage everything from any browser on your network. No app to install, no desktop GUI to learn.

How it works

Up and running in three steps

No configuration files. No port forwarding. No cloud account.

1

Install

Download and install CoveSync on each device. It registers itself as a background service and opens the required ports automatically.

2

Pair

Open the web UI on both devices. Enter the 6-digit trust code to pair them. That's it — they're connected and trusted.

3

Sync

Share a folder from one device to the other. CoveSync picks up changes automatically and keeps both sides in sync.

Pricing

Simple, honest pricing

Pay once, own it forever. No subscriptions, no renewals, no surprises.
