Webflow A/B testing questions

Can I install Otter without a Webflow app?

Yes. Otter uses Webflow's built-in Custom Code area, so no marketplace app or custom build is required.

Will tests work on Webflow CMS pages?

Yes. A site-wide installation loads on static and CMS-generated pages, and URL rules choose exactly where each test runs.

Can marketers build variants without code?

Yes. Otter's visual editor lets marketers change copy, styles, visibility, and layout on the live page.
