Sizzy

Developer browser built for shipping responsive apps fast

Active development

Sizzy is my long-running developer browser that shows every device layout side-by-side so responsive debugging takes minutes, not hours.

I am juggling platform upgrades, new device presets, and build tooling improvements to keep Sizzy feeling fresh. The latest focus is untangling Git issues and prepping new iPhone profiles so designers see exactly what users see.

There is a backlog of browser ergonomics I want to polish—including faster branch previews and easier device management—which the new branch layout unlocks.
