Key Features
Native Scroll Animations
Scrnpix creates animated GIF captures of scrolling pages as a core feature. URLBox specializes in static screenshot capture without native animation output.
Lightweight API Surface
Scrnpix offers two focused endpoints (/screenshot and /animate) with clear parameters. This simplicity makes integration faster when you need screenshots and animations only.
Edge-Cached Responses
Scrnpix caches responses for 60 seconds on Cloudflare's edge network, so repeated requests for the same URL return instantly from the nearest data center.
Configurable Scroll Easing
Choose from 15 easing functions — linear, ease-in, ease-out, and ease-in-out with quad, cubic, quart, and quint variants — to control animation smoothness.
Frequently Asked Questions
What can Scrnpix do that URLBox cannot?
Scrnpix offers scrolling GIF animations with 15 easing functions via a dedicated /animate endpoint. It also runs on Cloudflare Workers edge network for globally distributed low-latency responses.
Is URLBox better for high-volume screenshot capture?
URLBox has been around longer and may offer more advanced queueing features. Scrnpix uses Cloudflare edge caching to serve repeated requests quickly, which helps with high-volume use cases involving repeated URLs.
How does authentication differ between Scrnpix and URLBox?
Scrnpix uses an X-KEY header for API key authentication. URLBox uses a different authentication scheme. Both approaches secure your API access, so the migration effort is minimal.
