The Problem

Taking screenshots programmatically requires running headless Chrome — which needs server infrastructure, Puppeteer configuration, and handling timeouts, CORS, and rendering issues. Most developers don't want to manage this.

The Solution

Why Now?

Every SaaS with user-submitted URLs needs previews. Directory sites, social platforms, and monitoring tools all need screenshots. Running headless Chrome at scale is painful to self-manage.
