Scrnpix vs Puppeteer
Puppeteer is the Node.js library that powers headless Chrome automation. Scrnpix uses Puppeteer under the hood but wraps it in a hosted REST API with edge caching, SSRF protection, and GIF animation support.

Key Features
Puppeteer Without the Ops
Scrnpix runs Puppeteer on Cloudflare Browser Rendering so you never have to install Chrome, manage memory, or handle browser crashes yourself.
Animated GIF Output
While Puppeteer only captures static screenshots, Scrnpix adds a full /animate endpoint that generates scrolling GIF animations with 15 configurable easing curves.
Security by Default
Scrnpix includes SSRF protection that blocks private IPs and validates DNS resolution via DNS-over-HTTPS. With raw Puppeteer, you must implement this yourself.
Global Edge Caching
Scrnpix caches screenshots at the edge for 60 seconds on Cloudflare Workers, reducing latency for repeated requests without any additional configuration.
Frequently Asked Questions
Is Scrnpix built on Puppeteer?
Yes, Scrnpix uses Cloudflare's Puppeteer integration under the hood for browser rendering, but wraps it in a managed REST API with caching, security, and animation features.
Why use Scrnpix instead of running Puppeteer directly?
Running Puppeteer yourself means managing Chrome installations, handling browser crashes, scaling servers, and implementing security controls. Scrnpix handles all of that as a hosted service.
Can Puppeteer create GIF animations of scrolling pages?
Not natively. You would need to capture multiple screenshots and stitch them together with a separate library. Scrnpix provides this as a single API call with configurable easing and frame controls.
