Facts

Purpose

Calque turns a website screenshot into working HTML and CSS by measuring pixels rather than asking a vision model to interpret the image.github.com · 4 Oct 2026

Output

It can write a self-contained HTML file or a JSON specification of its measurements.github.com · 4 Oct 2026

Design measurements

It extracts design tokens including colors, type scale, weights, spacing, container width, gutters, and corner radii.github.com · 4 Oct 2026

Layout and images

It finds sections, columns, cards, buttons, alignment, and reading order, and can crop photographs from the screenshot as assets.github.com · 4 Oct 2026

Quality check

Its check command renders the rebuilt page in an installed Chrome-family browser and compares it with the screenshot pixel by pixel.github.com · 4 Oct 2026
