Ready to switch from Playwright to RenderPix? This guide walks through the API differences, code changes, and everything you need to complete the migration in under an hour.
Why migrate from Playwright to RenderPix?
The most common reasons: lower pricing, native n8n/Make.com integration, batch rendering, or template variables. This guide covers the API differences and code changes needed to complete the migration.
API differences
Playwright and RenderPix share the same core concept — send HTML, get an image — but the API design differs. RenderPix uses a single POST /v1/render endpoint with a JSON body. Authentication is via X-API-Key header.
Before (with Playwright)
# Playwright — typical request pattern
curl -X POST https://api.playwright.com/render \
-H "Authorization: Bearer YOUR_KEY" \
-d '{"html": "<div>Hello</div>", "width": 1200}'
After (with RenderPix)
# One API call. That's all.
curl -X POST https://renderpix.dev/v1/render \
-H "X-API-Key: YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"html": "<div style=\"width:1200px;height:630px;background:#0f0f0f;color:#fff;display:flex;align-items:center;justify-content:center;font-size:48px\">Hello, RenderPix</div>",
"width": 1200, "height": 630, "format": "png"
}' --output card.png
Migration checklist
- Sign up at renderpix.dev and get your API key from the dashboard
- Replace the API endpoint URL with
https://renderpix.dev/v1/render
- Switch authentication to
X-API-Key header
- Test with your existing HTML templates — no changes needed
- Update your n8n or Make.com workflow to use the RenderPix native node
- Cancel your Playwright subscription once you've verified everything works
What stays the same
Your HTML templates work without modification. PNG, JPEG, and WebP output formats are all supported. Width and height parameters are identical.
