Pium!

A global shortcut opens a compact bar above whatever you are doing. One query searches applications, Spotlight-indexed files and commands in a single ranked list.

Raycast grew from a launcher into a suite, with AI, cloud sync, a team plan and an extension store. Pium! is the launcher part, and stops there.
A command is a plugin, and a plugin is one readable JSON file in ~/.config/pium/plugins. Drop it in and it is searchable without a restart. No build step, no account, no store.
A plugin can take one argument. Press space on it and it becomes a pill, and everything typed after belongs to that plugin.

Bookmarks are the other half. Name a link, a file or a folder once in Settings and open it from the launcher afterwards. Put {{input}} in the destination and Pium! asks for a value first, which turns a search URL into something you can type into.
A bookmarked site is asked for its icon once and the answer is kept on your Mac. That request and the check for its own updates are the only things it sends anywhere.
