Website screenshot API | ApiFlash | WarmIndex

APIFlash is a screenshot API service that generates pixel-perfect screenshots of websites using the latest Chrome browser and AWS Lambda, targeted at developers and businesses needing scalable image captures.

🚀 Overview

APIFlash offers a clean and powerful API for capturing high-quality screenshots of any web page. Powered by up-to-date Chrome instances running on AWS Lambda, it ensures accurate rendering of modern websites, including dynamic JavaScript content, while scaling massively to handle millions of screenshots daily for over 13,000 businesses.

This project solves the problem of reliably generating screenshots of websites programmatically, eliminating the need to maintain your own headless browser setup. It provides features like full-page captures, ad-blocking, custom viewports, device emulation, and more, all through a simple HTTP API.

It's built for developers, SaaS teams, marketers, and indie makers who need screenshots for social previews, monitoring, documentation, or automation.

Founded by Timothée Jeannin and developed by a team of engineers at NetCube EURL in France since 2017, APIFlash was created to deliver a stable, cost-effective, pixel-perfect screenshot solution.
