Three approaches to HTML-to-image rendering in 2026: Puppeteer, Playwright, or a managed API like RenderPix. Here's when each makes sense.
Puppeteer is Node.js-only, Chrome-only, and requires self-hosting. Setup takes hours. Production requires careful memory management. Cold starts are common on serverless platforms.
Playwright supports Chromium, Firefox, and WebKit. More modern API than Puppeteer, better TypeScript support. Same self-hosting challenges.
Send HTML, get image. No servers to manage, no cold starts (pre-warmed pool), no Chromium crashes. Starts at $9/mo with 100 free renders/month.
| Puppeteer | Playwright | RenderPix | |
|---|---|---|---|
| Setup time | Hours | Hours | 5 minutes |
| Monthly cost (low vol) | $15-30 server | $15-30 server | $0-9 |
| Cold starts | Common | Common | None |
| n8n integration | DIY | DIY | Native node |
| Maintenance | You own it | You own it | Zero |
| Best at scale | 50k+/mo | 50k+/mo | Up to 50k/mo |
Puppeteer/Playwright: You're rendering 50,000+ images/month, have a dedicated DevOps engineer, and need complete control over the rendering environment.
Managed API: Everything else. For 99% of projects, the time and infrastructure savings pay for the API cost many times over.
100 renders/month. Full HTML control. Native n8n node.
