Show HN: WhimPop – A macOS menu that pops up under your cursor

Hacker News - Tue, 07/21/2026 - 3:30am

Hold down the right mouse button (or two fingers on a trackpad) and a panel opens at your cursor. Clipboard history, snippets, favorite apps, folders, files, and a timer. A short right-click still shows the normal context menu, so nothing about everyday clicking changes. The panel never takes focus, so pasting lands in the app you were just using.

The reason I made this was because I wanted to have a launcher that could be shown where my cursor was without having to reach for the keyboard if I was already using the mouse, and without having to give up any of my existing buttons.

Since then I’ve also added keyboard support (so I don’t have to reach for the mouse while having my hands on the keyboard). Being able to change the appearance of the app was important to me so it’s possible to change themes, fonts, number of columns and more.

It’s made with C# / .NET 10 with NativeAOT and AppKit. The app is fully native (no Electron or web views) and only around 10 MB on disk.

Pressing Space opens a fuzzy search with everything the app knows (clipboard, snippets, favorites, websites, timer etc).

It's Apple Silicon only (macOS 12+). The mouse triggers need the Accessibility permission. The keyboard shortcut and menu bar icon work without it. And I wrote a large share of the code with Claude Code, reviewing and testing as I went.

$19.99 one time, 30-day trial with all features, no account. I've been running it daily for weeks and the clearest sign it stuck: I miss it in the time it takes a new build to compile.
