Compare screen2api
Two honest comparisons, kept separate on purpose: capture libraries, which are free and end at a canvas, and server-side screenshot services, which render URLs in their own browsers and can't see what your logged-in user sees. Each page starts with where the other tool is the better choice.
screen2api vs html2canvas open-source library
The default answer to "screenshot a div in JavaScript" for over a decade — a pure-JS renderer with an enormous install base and no dependencies.
screen2api vs html-to-image open-source library
The actively maintained successor to dom-to-image: it serializes the node into an SVG foreignObject and rasterizes that, letting the browser do the layout.
screen2api vs Urlbox server-side API
A mature server-side screenshot API: send a URL, their rendering cluster loads it in a real browser and returns the image or PDF.
screen2api vs ScreenshotOne server-side API
A polished server-side screenshot API with thoughtful options — ad blocking, cookie-banner hiding, caching — and a transparent per-screenshot overage model.
