Welcome

UniClipboard keeps text, files, images, and rich payloads in sync across your devices — without a cloud account, an email login, or any infrastructure you have to run. Devices reach each other directly when they can, and fall back to an encrypted relay when they can't. The relay only ever sees ciphertext.

Why UniClipboard

• Private by construction. Payloads are encrypted with XChaCha20-Poly1305 from the moment they leave your clipboard. Local history is encrypted on disk too, including the search index.
• No account, no email. Devices belong to a space. Joining a space takes a one-time invite code and the space passphrase — there is no third-party identity provider in the loop.
• Works across networks. Same Wi-Fi, different home networks, or a mobile hotspot. Direct P2P first; encrypted relay fallback when NAT traversal fails. Connections recover automatically after sleep, Wi-Fi switches, or short outages.
• Rich payloads. Text, files, images, RTF, and HTML — not just plain text. Large files stream without loading into memory first.
• Keyboard-first. A quick panel built for hands-on-keys flow, with inline previews for text, links, images, code, and files.
• CLI parity. The uniclip CLI mirrors the GUI and works on headless servers, SSH sessions, and tmux workflows.
• Cross-platform. Windows, macOS, and Linux are all first-class.
• Mobile companion. Pair an iPhone with the UniClipboard iOS App (TestFlight public beta) — or the bundled iOS Shortcut — and on Android use any SyncClipboard-compatible client. Either way the phone exchanges clipboard with the desktop in both directions. Mobile is a companion — a plain HTTP client, not an iroh peer — and works on the LAN out of the box, or across networks via a server node or Tailscale.
