Automate the Browser with Workers Browser Rendering API

on YouTube ↗39m

" summary

Cloudflare Workers’ Browser Rendering API runs a patched Puppeteer in a remote browser isolation service so serverless code can launch a Chromium instance, navigate pages, take screenshots and generate PDFs, and scrape or measure performance metrics. Demos show saving images and PDFs to R2 storage, running end-to-end checks, and collecting JS/CSS coverage. Current practical limit is short lived browsers (~60 seconds, two concurrent) and a demo uses Durable Objects to extend sessions by ~10s. API is open beta with a waitlist.
