Your clipboard,
kept.

Holt remembers everything you copy. Press ⇧⌘V to find it again, and pair your Macs so a copy on one is a paste on the other.

What it does

Everything you copied, one shortcut away

Find it by typing

Type any part of what you copied. Every word has to match, so ssh 10.0 finds that one command from last week.

Paste where you were

Pick a clip and press return. Holt pastes it into the app you were typing in, without stealing focus.

Pin what you reuse

Pinned clips stay at the top and never expire. Your address, a sign-off, the command you always forget.

On every Mac

Pair your Macs once. Copy on one, press ⌘V on the other a second later. Pins and deletes sync too.

How sync works

Copy here. Paste there.

Pair two Macs with a 6-digit code, like an Apple TV. After that they stay connected and send each other what you copy. No Bluetooth, no account, and no need to be in the same room.

  1. Same Wi-Fi

    The Macs talk directly over your local network. Your clips never leave the house.

  2. Different networks

    Office and home, or a Mac on your phone's hotspot: they connect directly over the internet.

  3. Router in the way

    If a firewall blocks the direct path, a relay passes the data along. It's end-to-end encrypted, so the relay only sees bytes it can't read.

Privacy

Your clips are yours

  • History stays on your Macs. There's no Holt account and no Holt server.
  • Copies that password managers mark as private are never recorded.
  • Choose apps whose copies Holt should ignore.
  • Sync is end-to-end encrypted, and only your paired Macs can connect.
  • The code is open source under the MIT license. Read it, build it yourself.

Why an otter?

A holt is an otter's den, where it keeps what matters. Sea otters even carry a favorite stone tucked under their arm, everywhere they go. Skip does the same with what you copy: keeps it safe, and when you pair your Macs, skips it across to the other one.

Install

Get Holt

Download Holt, open the disk image and drag Holt to Applications. It needs macOS 14 or later on Apple Silicon.

Or with Homebrew:

brew install --cask snowztech/tap/holt

Releases are signed and notarized, so macOS opens Holt without warnings. On first launch, a short checklist walks you through the two permissions Holt needs. To build from source, see the README.

FAQ

Questions

Does sync use Bluetooth or Wi-Fi?

Neither directly. It uses your network connection, whatever it is: Wi-Fi, Ethernet or a phone hotspot. On the same network the Macs talk locally. Otherwise they connect over the internet.

Do my clips go through a server?

Usually not. Your Macs connect directly. When a router blocks that, an encrypted relay forwards the data. It can't read it, and it doesn't store it.

How is this different from Apple's Universal Clipboard?

Universal Clipboard needs Bluetooth, both devices nearby, and forgets a copy after about two minutes. Holt works across networks and keeps a searchable history.

What about passwords?

Password managers like 1Password and Bitwarden mark their copies as private, and Holt never records those. You can also tell Holt to ignore any app.

Is it really free?

Yes. Holt is MIT licensed and has no paid tier. It's made by snowztech.

Does it work on iPhone?

Not yet. The iPhone app is next on the roadmap.
