Everything you need to know about CustomFit.ai — from getting started to enterprise security.
CustomFit.ai is an AI-powered no-code A/B testing and website personalization platform built for D2C and ecommerce brands. It lets marketers run experiments and personalize their website without writing a single line of code.
No. CustomFit.ai is built for marketers. The visual editor works directly on your live site — click elements, make changes, set up targeting — all without developer involvement. Setup takes under 30 minutes.
You can run A/B tests, multivariate tests, split URL tests, and theme-level A/B tests. You can also set up personalization campaigns that show different content to different audience segments simultaneously.
Any page on your website: homepage, product pages, collection pages, landing pages, cart, and checkout (on Shopify Plus). You can test any visible element — headlines, images, CTAs, layouts, widgets, pricing displays, and more.
There is no hard limit. However, for reliable results, we recommend running no more than one test per page section simultaneously to avoid interaction effects between tests on the same page.
CustomFit.ai uses traffic-based pricing. Plans start at $250/month for up to 50,000 monthly unique visitors and $499/month for up to 100,000 monthly unique visitors. Enterprise pricing is available for larger traffic volumes.
