The record

Purpose: Calque turns a website screenshot into working HTML and CSS by measuring pixels rather than asking a vision model to interpret the image.
Output: It can write a self-contained HTML file or a JSON specification of its measurements.
Design measurements: It extracts design tokens including colors, type scale, weights, spacing, container width, gutters, and corner radii.
Layout and images: It finds sections, columns, cards, buttons, alignment, and reading order, and can crop photographs from the screenshot as assets.
Quality check: Its check command renders the rebuilt page in an installed Chrome-family browser and compares it with the screenshot pixel by pixel.
Claude integration: Calque ships as a Claude skill that supplies measurements for Claude to use when writing project code.
Other tools: The documented workflow uses Tesseract for OCR and Docker as an optional way to run Calque in a container.
Privacy and operation: The maker says Calque makes no model call or API request, and that after its OCR data is cached it works offline; the Docker build preloads that data.
Runtime: The maker says Calque runs in about a second per page and its tests run without network access.
Limits: It processes one screenshot rather than a whole site, cannot identify the exact typeface, and uses cropped screenshot images rather than recovering original photographs.
Known weak cases: The maker reports lower reconstruction matches for photograph-heavy pages and identifies dark pages with large glows or gradients behind text as its worst case.
License: The repository describes Calque as MIT-licensed and says it can be hosted, forked, or sold.
Maker: The repository says Calque is part of Openware, whose GitHub profile describes its work as self-hostable replacements for subscription software.
