Pixel grid
A 16px lattice you can actually ship against.
Presets at 4, 8, 16, 24, 32, and 64. Switch units to px, rem, or fr. Opacity is a slider, not a guess. Option/Alt+G.

Try it here · then take it to any page
Starts off-axis. Grid wakes, guides pull, logo parks dead center. Capsule in the corner is live — no install, no account.
The 16px grid stays in this banner. The capsule in the corner is the real toolbar — grid stays off the rest of the page until you turn it on.
On the live page
Working mocks, not mockups. Hover or tab in. On a phone, scroll until it plays.

Rulers and guides
Drag from a ruler. Shift keeps it on the current cell. Option/Alt+H or V drops a center guide. The hostname remembers where you left them.
Hover to pull the guides
Measure
Shift locks a straight run. Caps Lock snaps 15°. The readout sits on the page, not in a panel you have to keep open. Option/Alt+M.
Hover to draw the line
Inspect
Hover any node. Click to pin. Double-click to clear. Turn on ID and classes when you need the selector, not before. Option/Alt+I.
Hover to pin the highlight
Capsule toolbar
Light or dark with the system. Mac writes Option. Windows writes Alt. Settings apply as you change them. Nothing leaves the machine.
