Developers get different things from a notch app: OneNotch for clipboard transforms such as Base64, JSON and MD5, Droppy and SuperIsland for extension SDKs, Crest for agent approvals, and NotchStar for live system stats and a Disk tool at $4 once. Checked 4 November 2026.
How we checked
Each app’s official page, repository or App Store listing was read on 4 November 2026. The labels below say what a developer might use the app for, based on the feature wording on those pages. There is no ranking. If a page did not state a feature, it is not claimed here. Prices as of 4 November 2026.
The entries
NotchStar: best for system stats and disk cleanup at a low price
The System Stats tool shows CPU, memory, disk, battery and network speed as live gauges, and sampling only runs while the tab is open. The Disk tool covers free space, big folders, duplicates and app leftovers, and everything it removes goes to the Trash. Clipboard history keeps the 50 most recent items in memory and skips copies a password manager marks as concealed. The limits: it has no extension system, no window snapping and no coding agent features, and the code is closed. It costs $4 once for up to 3 Macs and needs macOS 14 or later.
OneNotch: best for clipboard work on code and data
Its clipboard offers 15 right click transforms including Base64, JSON and MD5, search filters such as @image and @link, a Copy Stack and up to 20 boards with 200 items each on Pro. Free keeps 50 items for 24 hours. It needs macOS 15 or later and its site says Built for Apple Silicon without mentioning Intel.
Droppy: best for extensions and a public SDK
Droppy ships 41 free extensions, which it calls droplets, with a public SDK called DroppyKit. It lists live activities for coding agents, a clipboard history with pins and tags, and a file tray that zips and converts files on the Mac. It is $9.99 once for two Macs. Its Droppy Cloud links expire after 3 days.
SuperIsland: best for writing your own modules in JavaScript
Free, with a JavaScript SDK and an extension store, and AI agent alerts through a community extension. There has been no release since June 2026, a physical notch is required, and the repository shows no license file.
NotchThings: best for process and network checks
NotchThings lists CPU, memory and network stats, active processes, usage alerts, a Speed Test, a Keep Awake control aimed at long running agents, a color picker and AI usage tracking. It requires macOS 15.6 or later, and its pages state no refund policy.
Crest: best for approving coding agent prompts
Crest opens Claude Code, Codex and Copilot CLI permission prompts in the notch, adds a passwords and 2FA authenticator, and sends files between notches. It is $14.99 once, covers 2 Macs, and updates are included through Crest 7.
Atoll: best for open source system and clipboard tools
GPL 3.0, with a clipboard history, a color picker and stats for CPU, GPU, memory, network and disk. Its acknowledgments credit a terminal tab. It asks for Accessibility, Camera, Calendar, Screen Recording and Music permissions.
Brow: best for replacing several developer utilities with one free app
Brow Free has 40 or more tools including a launcher on Option and Space, window management, clipboard history with snippets, screenshots with OCR and fan control. All listed releases are beta, and its AI tools are on the paid Pro plan.
Sapphire: best for window tiling and an audio mixer without paying
The free tier lists Snap Zones window tiling, a per app audio mixer with a 10 band EQ, Caffeinate and a file shelf. The source is under AGPL 3.0. Paid AI plans start at $15.99 a month.
What to check before you pay
Developer machines are often the newest, so the macOS floor matters less here than on other lists, but it still splits the group. OneNotch needs macOS 15, NotchThings needs macOS 15.6 and Sapphire needs macOS 14.6, while NotchStar, Droppy, Crest, Brow and SuperIsland run on macOS 14. Chip support also differs: OneNotch is built for Apple silicon, and Crest and NotchStar list both Apple silicon and Intel.
Permissions deserve a read. Atoll asks for Accessibility, Camera, Calendar, Screen Recording and Music access, and Sapphire asks for Accessibility and Screen Recording. The NotchStar safety guide lists what NotchStar asks for and what leaves the Mac, as a model for the questions to ask any app. Prices as of 4 November 2026.
How to choose
- You copy JSON, Base64 or hashes all day: OneNotch, on macOS 15 or later with Apple silicon.
- You want to write your own widgets: Droppy (DroppyKit) or SuperIsland (JavaScript).
- You run coding agents: see the AI coding agents list first.
- You want window tiling: Brow or Sapphire. NotchStar does not have it.
- You want live system stats and disk tools for a small payment: NotchStar, or NotchThings if you are on macOS 15.6 or later.
