Plugins

What plugins are

The Omarchy desktop runs as a single long-lived Quickshell process, and nearly everything on screen is a plugin inside it: the bar, the panels that drop from it, the emoji picker, the clipboard manager, the menu, the lock screen, and the background services. First-party plugins ship with Omarchy; anything you add lives in ~/.config/omarchy/plugins/.

A plugin is a directory with a manifest.json and some QML. Its id is namespaced — the omarchy. prefix is reserved for first-party plugins.

When a theme wants a plugin

The line is straightforward. A theme changes colour. A plugin changes behaviour or structure. If what you want is not expressible in colors.toml or shell.toml, you want a plugin.

What you wantWhere it belongs
Different colours anywhere in the desktopTheme — colors.toml
Different bar height, corner radius, border widths, font scale, spacingTheme — shell.toml or a shell.<section>.toml override
A different lock-screen or notification treatmentTheme — shell.lock.toml, shell.notifications.toml
A new item in the bar, or a bar laid out differentlyPlugin
A new panel, overlay or background servicePlugin
Behaviour that reacts to system statePlugin

Plenty of visual ambition is reachable without a plugin: shell.toml covers bar sizing, control states in every interaction state, per-side border widths, gradient borders, corner radius and the typographic scale. Try that first — it installs with your theme and needs no trust from the person installing it.

Plugins are code, themes are not

This distinction is the reason the two are separate. An installed theme is filtered down to colour before it is staged. A plugin is not: it runs as unsandboxed code inside your long-lived shell process, for as long as your session lasts, with everything your user account can reach.

Omarchy says so plainly and asks you to confirm before adding one. It clones files, validates the manifest and flips a setting — it never runs an install hook and never asks for sudo — but that only covers installation. Read a plugin before you enable it, and link plugins from your theme with the same care you would recommend any other program.
