The lag is the feeling

Every movement has a personality.

Lagga is named for the trail that follows late. The cursor leads. A spring catches up. That delay is the instrument — not a faster mouse, and not a performance tuner.

Stiffness 90 · damping 5 · leash 150. It arrives late and keeps a little swing.

Up to four trails

Layer the impossible.

Cosmic Trinity is a real bundle: Nebula, starlight, and aurora in divine alignment Each trail keeps its own leash.

36 presets and 68 bundles ship with the desktop app. The crosshair here is a sample path, so the bundle can play while you read.

The Windows application

A window for the settings. A sky for the cursor.

Choose your look, tune every trail, then switch on the overlay. The light follows across your Windows desktop while your clicks pass through to the apps underneath.

Lagga configuration window on the Global tab, with master opacity, scale, wind, performance mode set to Auto, and the overlay toggle.
The real Lagga app · Global controls. The transparent cursor overlay runs separately.

Global

Master opacity, scale, hue, wind, a performance mode, idle dimming, and optional bundle swapping. The overlay toggle sits in the corner.

Presets

Apply one look, or a bundle that fills up to four trail slots. Random bundles stay inside a shared energy so the mix still feels intentional.

Trails

Each slot has its own enable switch, physics, color, length, and render mode. Showing three slots does not force all three to be on.

Advanced

Afterimages, echoes, comet heads, breathing, click gravity wells, magnetic push between trails, and idle patterns when you stop moving.
