Omaclip

A desktop clipboard manager for Omarchy that works on Linux and macOS. It tracks your clipboard history, lets you browse and copy items, and is designed for a keyboard-first workflow. Run it on multiple machines and they form a secure mesh, automatically discovering each other and sharing their clipboards.

It works on Linux and macOS, but it loves Omarchy, hot-reloading its color scheme the moment your OS theme changes.

• In-memory clipboard history text and images (PNG/JPEG), up to 50 items (configurable)
• Keyboard navigation with shortcuts for quick copying (Ctrl+1..9)
• Expandable entries for viewing long text or larger image previews
• Image file copy support: copying an image file from a file manager (Finder, Nautilus, etc.) captures the actual image, not just the filename
• Live theme loading for Omarchy 3 and 4; colors update automatically when you switch themes
• Secure multi-machine sync, peers discover each other via mDNS and sync over HTTPS with certificate validation and a shared passphrase; only machines with the same passphrase can connect
• Optional mDNS interface binding for multi-NIC setups
• Manual peer configuration and fixed sync server port for VPN/routed networks

Installation

Option 1 — AUR (recommended for Arch / Omarchy)

yay -S omaclip-bin

Option 2 — One-liner

The install script detects your OS, architecture, and package manager, installs the required dependencies, and places the binary in /usr/local/bin.

curl -fsSL https://raw.githubusercontent.com/rhemvi/omaclip/master/install.sh | sh

Option 3 — Manual installation

Linux

Install the runtime dependencies for your distro, then download and install the binary.

Debian / Ubuntu

sudo apt install libgtk-3-0 libwebkit2gtk-4.1-0 xclip
curl -fsSL https://github.com/rhemvi/omaclip/releases/latest/download/omaclip-linux-amd64 -o omaclip
sudo install -m 755 omaclip /usr/local/bin/omaclip

Arch Linux

sudo pacman -S --needed gtk3 webkit2gtk-4.1 wl-clipboard
curl -fsSL https://github.com/rhemvi/omaclip/releases/latest/download/omaclip-linux-amd64 -o omaclip
sudo install -m 755 omaclip /usr/local/bin/omaclip

Fedora / RHEL

sudo dnf install gtk3 webkit2gtk4.1 wl-clipboard
curl -fsSL https://github.com/rhemvi/omaclip/releases/latest/download/omaclip-linux-amd64 -o omaclip
sudo install -m 755 omaclip /usr/local/bin/omaclip

openSUSE

sudo zypper install libgtk-3-0 libwebkit2gtk-4_1-0 xclip
curl -fsSL https://github.com/rhemvi/omaclip/releases/latest/download/omaclip-linux-amd64 -o omaclip
sudo install -m 755 omaclip /usr/local/bin/omaclip

For ARM64 machines replace omaclip-linux-amd64 with omaclip-linux-arm64.

macOS

No extra dependencies needed, macOS already ships with WebKit.

# Intel
curl -fsSL https://github.com/rhemvi/omaclip/releases/latest/download/omaclip-darwin-amd64 -o omaclip
sudo install -m 755 omaclip /usr/local/bin/omaclip

# Apple Silicon (M1/M2/M3)
curl -fsSL https://github.com/rhemvi/omaclip/releases/latest/download/omaclip-darwin-arm64 -o omaclip
sudo install -m 755 omaclip /usr/local/bin/omaclip

Configuration

Omaclip can be configured via CLI flags or environment variables. Run omaclip --help to see all options.

Passphrase

On first launch, omaclip will prompt for a passphrase used to secure peer sync. It is saved by default to ~/.config/omaclip/config.json. All machines must share the same passphrase to discover and sync with each other.

Copy hook

--copy-hook runs a shell command after Omaclip successfully writes a selected local or remote entry to the system clipboard.

To verify the hook is running, show a desktop notification after copying an entry:

omaclip --copy-hook='notify-send "Omaclip" "Copy hook triggered"'

For example, if Omaclip is open on a Hyprland special workspace named scratchpad, this closes the workspace, restores focus to the previous window, and pastes the selected entry with wtype:

omaclip --copy-hook='hyprctl dispatch "hl.dsp.workspace.toggle_special(\"scratchpad\")" && sleep 0.2 && wtype -M ctrl -M shift -P v -p v -m shift -m ctrl'

Example Hyprland scratchpad setup

Check the example Hyprland scratchpad setup to start Omaclip in the scratchpad, close the scratchpad after selecting an entry, and paste it at the current text cursor location.

mDNS interface binding

By default, mDNS peer discovery uses IPv4 multicast on all eligible network interfaces. On machines with multiple NICs (e.g. WiFi + Ethernet), it is recommended to set --peers-mdns-interface so both mDNS advertising and browsing use the intended local network interface.

This is useful for local mDNS networks. VPNs such as Tailscale generally do not carry mDNS multicast between machines, so use manual peers for those setups.

# CLI flag
omaclip --peers-mdns-interface en0

# Environment variable
export OMACLIP_PEERS_MDNS_INTERFACE=en0

Common interface names: en0 (macOS WiFi), wlan0 (Linux WiFi), eth0 (Linux Ethernet).

To make it permanent, add the export to your shell profile (~/.zshrc, ~/.bashrc, etc.).

Manual peers and fixed sync port

By default, omaclip uses mDNS to discover peers on the local network and starts its sync HTTPS server on a random OS-assigned port. For VPN or routed networks such as Tailscale, mDNS may not cross network boundaries and the random port can change after restart. In that setup, run each machine with a fixed sync server port and manually list the other peers by Tailscale IPv4 address:

# On this machine, listen on a stable port and pull from davel over Tailscale
omaclip --sync-server-port=36742 \
  --peers-list=davel@100.101.102.103:36742

Use the same passphrase on every machine. The name@ prefix is optional and is only used as the display name; the address must be an IP and port. To specify multiple peers, separate them with semicolons and quote the value in your shell: --peers-list='davel@100.101.102.103:36742;alice@100.104.105.106:36742'. When --peers-list is set, mDNS discovery is skipped entirely.

Environment variable equivalent:

export OMACLIP_SYNC_SERVER_PORT=36742
export OMACLIP_PEERS_LIST=davel@100.101.102.103:36742

Run this on every machine that should participate in the mesh. Each machine should use its own fixed --sync-server-port and list the other machines with their respective Tailscale IPs in --peers-list; once both sides point at each other, their clipboards sync between them.

For example, on alice:

omaclip --sync-server-port=36742 \
  --peers-list=davel@100.101.102.103:36742

And on davel:

omaclip --sync-server-port=36742 \
  --peers-list=alice@100.104.105.106:36742

Live Development

To run in live development mode, run wails dev in the project directory. This will run a Vite development server that will provide very fast hot reload of your frontend changes. If you want to develop in a browser and have access to your Go methods, there is also a dev server that runs on http://localhost:34115. Connect to this in your browser, and you can call your Go code from devtools.

Building

To build a redistributable, production ready package, run:

task app:build

Known Limitations

Clipboard monitoring on GNOME/Mutter (Wayland)

On desktops that use GNOME's Mutter compositor (Fedora, Ubuntu, Pop!_OS, etc.), clipboard monitoring may cause brief focus flicker. This is a Wayland security restriction: the standard clipboard protocol only delivers content to the focused window, so wl-paste must briefly acquire focus on each poll cycle.

Compositors built on wlroots (Hyprland, Sway, etc.) are not affected because they support the wlr-data-control protocol, which allows background clipboard access without focus changes. On these compositors, omaclip uses event-driven watching with wl-paste --watch and no polling is needed.

X11 sessions and macOS are also unaffected.
