Rendex
Rendex runs headless Chromium across a global edge network to turn live URLs, raw HTML, or Markdown into pixel-perfect PNG, JPEG, WebP, or PDF output, including full-page scroll-stitched captures. It also supports templated batch jobs across many URLs at once and HMAC-signed webhook callbacks, on a metered free tier with paid plans billed per rendering call.
