Snapshot renders screenshots and Open Graph images through an API, using Cloudflare's Browser Rendering fleet, so there is no headless Chrome binary in your deploy. GET /shot returns a PNG, JPEG or WebP of any URL; GET /og builds a 1200x630 social image from a title and subtitle, or POST your own HTML template. Renders are cached 24 hours by content hash, so repeat requests are free. Free tier: 100 renders/month. Paid: $19 for 2,000, $49 for 20,000.
