The Problem
Every time I tried to take full-page screenshots or generate clean PDFs using Puppeteer, I ran into the same frustrating issues:
- 🖼️ Blank images from lazy-loading (data-src, data-original attributes)
- 🍪 Cookie banners blocking half the screen
- 🤖 Cloudflare blocking my headless browser instantly
- 📄 PDFs with ugly page breaks cutting images in half
What I Built
I created Hermes API — a Puppeteer wrapper that solves all of these problems automatically.
Key features:
- ✅ Smart Lazy-Load Agent: Uses a MutationObserver to intercept
data-src,data-lazy-src, anddata-originalattributes and force-loads every image before taking the screenshot - ✅ Stealth Plugin + Bot Evasion: Injects real browser fingerprints to bypass Cloudflare and similar protections
- ✅ Auto Ad/Cookie Blocker: Powered by Ghostery to remove popups automatically
- ✅ Single-Page PDF Export: Generates PDFs without ugly mid-image page breaks
- ✅ QA Agent: Analyzes the page and gives it a score from 0 to 100, flagging broken images, bot blocks, and empty pages
Try It
I built a public dashboard so anyone can test it without writing code:
🔗 https://hermes-api-pro.onrender.com/
⚠️ There's a strict rate limit (3 requests per 10 min per IP) on the public dashboard to keep my free server alive. If you hit it and want a real API Key, there's a contact button right on the page.
Feedback Welcome!
This is an MVP. Would love to hear if you manage to find a URL that breaks it, or any suggestions on what features to add next!
