Sync your files and clipboard across all your devices. Fast, private, no subscription.
Synclip is a lightweight encrypted file sync daemon and P2P clipboard sharing tool. It runs silently in the background, watches your folders for changes, and syncs only what changed — no full re-uploads, no cloud subscriptions, no one else has access to your data.
