Comparison
Choose SyncClipboard if you want a server/WebDAV/S3 backend. Choose UniClipboard if you want desktop clipboard sync across networks without running your own server.
SyncClipboard and UniClipboard both sync clipboards across platforms, but SyncClipboard is built around configurable sync backends while UniClipboard focuses on peer-to-peer, end-to-end encrypted desktop sync.

TL;DR
SyncClipboard
SyncClipboard is strongest when you are comfortable using a server or server-like backend: a standalone ASP.NET Core server, a desktop client built-in server, WebDAV, or S3-compatible storage. That flexibility is useful for users who already run infrastructure.
UniClipboard
UniClipboard is strongest when you want two desktops to sync directly across networks without setting up infrastructure. It prioritizes peer-to-peer transfer, automatic NAT traversal, encrypted relay fallback, and end-to-end encryption by default.
Side by side
| Feature | UniClipboard | SyncClipboard |
|---|---|---|
| Best fit | Peer-to-peer desktop clipboard sync across networks. | Server/WebDAV/S3-based clipboard sync and history management. |
| Desktop platforms | Windows, macOS, and Linux. | Windows, macOS, and Linux. |
| Mobile support | Native iOS (public beta on TestFlight) and Android apps; the Android client stays protocol-compatible with SyncClipboard for LAN use. | Mobile workflows are available through companion tools, third-party tools, and compatible clients. |
| Server requirement | No user-run server required for desktop-to-desktop sync. | Requires a reachable sync backend such as standalone server, built-in server, WebDAV, or S3. |
| Cross-network model | Peer-to-peer first, with NAT traversal and encrypted relay fallback. | Clients connect to a configured server or storage endpoint. |
| Privacy model | End-to-end encrypted transfer plus encrypted local history and search index. | Can be deployed securely, but the operator must configure the transport path; the README warns that plain HTTP transmits data in plaintext. |
| Clipboard history | Local encrypted history with full-text search. | History management and history sync; the README notes the history feature is early-stage and should not be the only place important data is stored. |
| CLI and automation | Includes the headless uniclip CLI for terminals, SSH, scripts, and tmux workflows. | Documents desktop command-line arguments and exposes server APIs for integrations. |
| License | AGPL-3.0. | MIT. |
| Implementation | Rust and Tauri. | C# with an ASP.NET Core server ecosystem. |

Verdict
SyncClipboard is a strong choice when you want a mature server/WebDAV/S3 clipboard sync system. UniClipboard is the sharper tool when your main pain is syncing desktops across networks without maintaining a server, while keeping clipboard contents end-to-end encrypted by default.
FAQ
No. UniClipboard's desktop app is a separate Rust/Tauri project. Its Android client is forked from SyncClipboard and remains protocol-compatible for LAN mobile companion use.
Yes. SyncClipboard supports Windows, macOS, and Linux desktop clients, and its documentation covers mobile workflows through companion tools and third-party clients.
For desktop-to-desktop sync, no user-run server is required. UniClipboard uses peer-to-peer transfer where possible, NAT traversal across networks, and encrypted relay fallback when direct connection fails.
It needs a reachable sync backend. That can be the standalone server, a desktop client built-in server, WebDAV, or S3-compatible storage.
Both can work well. SyncClipboard is a good fit if you like the server/backend model. UniClipboard is a good fit if you want the same tool to continue working when your desktops are no longer on the same LAN.
It depends on the deployment. SyncClipboard can be deployed securely with HTTPS and trusted storage. UniClipboard makes end-to-end encryption and encrypted local storage part of the default product model, so there is less infrastructure for the user to secure.
Because the UniClipboard Android client is forked from SyncClipboard and protocol-compatible. That is a practical bridge, not a claim that the two desktop products have the same architecture.
Try UniClipboard
Install UniClipboard on your desktops and pair them directly. Copy on one machine, paste on another — even when they are not on the same network.
