FRAME / COMPARE
Comparing interface versions side by side so every visual change becomes visible.
Context
The hardest changes to discuss in design review are rarely complete redesigns. They are small shifts in spacing, weight, and alignment. Switching between two pages from memory makes those shifts easy to miss.
Approach
Frame / Compare offers side-by-side, split, and flicker modes. Every mode shares the same viewing model, keeping the conversation on the change itself.
Engineering focus
Image decoding, zoom, and dragging are separated to avoid repeated work with high-resolution screenshots. Keyboard shortcuts cover the primary actions for fast review sessions.
Takeaway
The most useful part of a tool is not always more data. It can be a shared way to look. Explicit comparison modes make vague “it feels different” conversations easier to turn into concrete observations.
