Outdated engine

wkhtmltopdf alternatives

wkhtmltopdf uses an outdated WebKit engine that lacks CSS Grid, custom properties, and modern layout support.

SaaS vs self-hosted

Urlbox alternatives

Urlbox is a paid SaaS screenshot API. Compare it with free, self-hosted options that keep your data on your infrastructure.

Self-hosted vs self-hosted

puppeteer-renderer alternatives

puppeteer-renderer converts URLs to screenshots and PDFs. Compare it with Openkova, which adds HTML snippet input, file uploads, crawling, and SSE streaming.
