What the CSS Scrollbar Gutter does
Preview stable scrollbar gutter spacing for panels that should not jump when content overflows. A settings drawer with optional filters can reserve both edges before the scrollbar appears Adjust the controls and the preview updates immediately, so you can dial in exactly what you want and copy the result straight into your project — no build step and no account.
One thing to keep in mind: The output uses scrollbar-gutter, so older browsers may ignore the reservation and fall back to normal overflow behavior.
Private and in your browser
Everything runs locally in your browser. Your input is never uploaded, so the tool stays fast and works offline, and the copy and download buttons always use the current result shown in the output panel.
