# Puppeteer

14 Hacker News commenters recommended Puppeteer and 16 criticized it, November 2025 to November 2026. It was recommended in 10 of 13 months.

**Verdict:** Node.js library for driving headless Chrome from code, used for browser testing, screenshots and PDF rendering. Critics say its scripts are brittle and it struggles with scale and AI agent browsing.
