Urlbox
Replaceable in one session with an AI coding agent.
A screenshot API: give it a URL and it returns a rendered image or PDF, handling fonts, cookie banners, lazy loading and full-page capture.
Build a screenshot service with Playwright. STACK - Playwright in a container, a queue table, S3-compatible storage THE ENDPOINT - POST a URL and options; return a job id, not an image. Rendering is too slow to hold a request open - The job writes to storage and the result is fetched by id GETTING A GOOD SHOT - Wait for networkidle, then wait for fonts.ready — a screenshot taken before fonts load looks broken - Scroll to the bottom and back to trigger lazy images, then wait again - Inject CSS to hide cookie banners and disable animation SAFETY, WHICH MATTERS HERE - Never render a URL from an untrusted source without a domain allow list: a rendering service is a request forgery hole - Block private address ranges explicitly CACHING - Key on the full option set; identical requests return the stored image Include the worker, the wait sequence and the allow list.
What you lose
- A fleet of browsers somebody else keeps patched and warm
- Handling for cookie banners, lazy-loaded images and web fonts that arrive late
- Capacity for a burst of requests without you provisioning anything
If you would rather not build
- Puppeteer, for the same job

87/100
Verdict yes at 87. Playwright does the rendering; the font and lazy-loading waits are what make the output usable, and the allow list is what keeps it safe.
