Can I add a carousel slider to Framer without code?

Mostly yes. Add the script tag in Settings > Custom Code, then use an Embed component with your carousel HTML. You write HTML markup but no JavaScript or React code.

Does the carousel work on Framer's free plan?

The Embed component works on all plans, but the Custom Code section in Site Settings requires a Basic plan ($10/mo) or higher. On the free plan, you could add the script inside the Embed itself.

Do I need to write a Framer Code Component?

No. The Embed approach works for most use cases. Code Components are only needed if you want a reusable carousel with configurable properties in Framer's design panel for non-coders.
