Doppio

Do you offer a free plan?

Yes. Our Basic plan is completely free with up to 400 documents per month. No credit card required.

Is there a timeout for renders?

The default timeout is 30 seconds per render. For complex documents, use asynchronous render mode with extended timeouts.

Does my page need to be publicly accessible?

No. You can pass raw HTML directly, use templates, or use authentication headers to access private pages.

Can I use non-Amazon S3 storage?

Yes. We support any S3-compatible storage including Google Cloud Storage, DigitalOcean Spaces, and MinIO via presigned URLs.

How do you handle data privacy?

Each render runs in an isolated instance terminated after processing. Documents are never stored on our servers. GDPR compliant, EU-hosted.

What rendering engine does Doppio use?

Doppio uses managed Chromium instances running the latest stable version. This ensures full HTML5, CSS3, and JavaScript support with the same rendering fidelity as Google Chrome.

How does Doppio compare to wkhtmltopdf?

Unlike wkhtmltopdf which relies on a deprecated WebKit engine, Doppio uses modern Chromium for superior CSS support (Flexbox, Grid, variables). It's a fully managed API, so there is no server installation, maintenance, or scaling to worry about.

Can I use custom fonts and webfonts?

Yes. Doppio supports the full Google Fonts library out of the box, plus any custom font loaded via CSS @font-face in your HTML. Webfonts render accurately in both PDF and screenshot outputs.
