render-quality

Score a rendered web page 0-1 and name why it failed. This is the scorer behind EnConvert's render_quality, as a zero-dependency library (ESM and CJS). Full documentation, the deduction table and the Python package live in the repository README: https://github.com/enconvert/render-quality

npm install @enconvert/render-quality

import { score, QUALITY_FLOOR } from "@enconvert/render-quality";

const verdict = score(html, { statusCode: response.status });
if (verdict.is_blocked || verdict.render_quality < QUALITY_FLOOR) {
  console.warn("failed render", verdict.deductions, verdict.reasons);
} else {
  ingest(html);
}

Adapters: fromCrawl4ai(result), fromFirecrawl(scrapeJson), fromJina(markdown, statusCode). Markdown-only input goes through scoreText, which runs the text-based rules and marks the verdict html_unavailable.
