When to choose Selenium

Selenium (classic browser automation framework) is a solid choice when you specifically need its core strength: browser automation. If you're already invested in the Selenium ecosystem — API integrations, team familiarity, existing templates — there's no pressing reason to switch.

When to choose RenderPix

RenderPix is the better choice for automation-first workflows. The native n8n node means you can add HTML-to-image rendering to any workflow with no custom code. Batch rendering, template variables, and async callbacks are all built in. And at $9/mo, it's among the most affordable options in the space.
