@getrefractjs/core

Rendering engine behind Refract — agent-first responsive screenshots.

render() captures a URL at N device viewports (one Chromium browser, one context per viewport, rendered in parallel) and returns screenshots plus structured findings: horizontal overflow, clipped elements, truncated text, sub-44px tap targets, and images missing alt.

import { render } from '@getrefractjs/core';

const shots = await render({ url: 'http://localhost:3000' });
for (const shot of shots) {
  console.log(shot.preset, shot.savedPath);
  for (const f of shot.findings) console.log(' ', f.severity, f.type, f.detail);
}

Everything is optional except url. Needs Chromium once: pnpm exec playwright install chromium (add webkit for engine: "webkit"). MIT licensed.
