What the publisher says
From the Plonk repository's README, as published. We do not edit it. Read it on GitHub
Plonk
A toolbox for your Mac, behind one menu bar icon. Windows, workspaces, screenshots, OCR, a ruler, keep-awake, pointer tools, shortcuts, voice and agents — native, local and modular. To plonk is to set a thing down exactly where it belongs.
ostapondo.github.io/Plonk
One app instead of eight menu bar icons
Plonk is a small suite of macOS tools that share one interface, one command palette and one automation surface. Use all of it, or switch off every module you do not need.
Capture and understand the screen. Take a region, window or full-screen screenshot, annotate it, pin a live crop, copy otherwise unselectable text with on-device OCR, or measure an interface in points and pixels.
Keep the Mac and your workflow moving. Hold sleep off until a timer, time of day or process exit; find the pointer, add crosshairs or click rings; inspect the front app's real shortcuts; and run anything by name from one palette.
Arrange the desk. Draw snap zones, save workspaces that remember each monitor, move windows by drag, shortcut or voice, and let app rules put new windows where they belong.
Let an agent use the same tools. Plonk ships an MCP server and CLI for layouts, workspaces, screenshots, OCR, measuring, keep-awake and the rest. The app stays the source of truth, and the whole surface remains on your Mac.
It is early. Version 0.4.x, one author. Shortcuts, zone files and workspaces are settled. The MCP tool names and the HTTP API are not, and can still change between minor versions. CHANGELOG.md says what moved.
Install
macOS 13 or newer, Apple silicon.
brew install --cask ostapondo/plonk/plonkGrant Accessibility when it asks, then relaunch. Screen Recording is asked for separately, the first time you capture. Nothing else: no Full Disk Access, no Automation, no Keychain.
Plonk is signed but not notarized, so macOS holds a copy you download by hand. The cask takes care of that for you.
Running it alongside Rectangle or Magnet is fine, as long as their shortcuts do not collide.
Checking what you downloaded. Notarizing an app means paying Apple for a developer account, and this project does not have one, so Plonk is signed with a certificate it made itself. That means macOS cannot tell you who built the app. There is a check that answers a more useful question, and you can run it yourself: was this exact file built by GitHub from the source in this repository?
gh attestation verify Plonk-<version>.zip --repo ostapondo/PlonkShortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
