Calque vs Kombai

Calque is a free, MIT-licensed tool that turns a PNG or JPEG website screenshot into HTML and CSS by measuring pixels. It can produce a self-contained HTML file or JSON measurements, including colors, type scale, weights, spacing, container width, gutters, and corner radii. It also identifies sections, columns, cards, buttons, alignment, and reading order, and can reconstruct vertical gradients. With the assets option, it crops photographs from the screenshot for use in the output. Its check command renders the result in an installed Chrome-family browser and compares it pixel by pixel with the screenshot. Calque is packaged as a Claude skill that provides measurements for Claude to use when writing project code. The documented workflow uses Tesseract for OCR; Docker is optional. The maker says it makes no model call or API request and works offline after OCR data is cached. It handles one screenshot, not a whole site, and cannot identify an exact typeface. Icons become placeholders, and photo crops retain screenshot resolution and any overlaid text.

Kombai is an AI design engineer for designing and coding websites and product interfaces. Users can explore work on an infinite canvas, ship code in a repository, and refine it in an editable browser. Its native Figma integration parses complex files, addresses messy grouping and invisible layers, and extracts icons and assets. Context Graphs give Kombai semantic understanding of repository code so it can reuse components, hooks, tokens, and types. It applies practices for more than 400 frontend libraries and frameworks, including React, Vue, Angular, Svelte, Next.js, Tailwind, shadcn/ui, and MUI. Kombai can test user flows in a browser and inspect console logs, network activity, performance data, and styles; it can also run lint and build checks and investigate runtime errors. Users can connect external services through MCP servers or run existing Claude Code or Codex subscriptions inside Kombai. It is available as a desktop app and IDE extension, but there is nothing to install on a phone. The Free plan has monthly credit limits; paid plans start at $20.00 per month.
