Your tech stack and tools

The core stack (everything you actually need)

• Intempt console (Experiences, Catalog) (This is where you build tests, personalizations and recommendations)
• intempt-js web SDK (This is what applies your changes on your live site)
• Experiences (This is where every test and personalization lives)
• Catalog and Feeds (This is your product data, ready to recommend anywhere)
• Choose API (This is how your server decides which version each visitor gets)

Highly recommended optional upgrades that level up your work

• Shopify (This is the fastest way to load your products if you sell on Shopify)
• Custom catalog source (This is how you load products from any other store)
• Node SDK (This is the easy way to call experiments from a Node backend)
• Statistical significance (This is how you know a winner is real, not luck)

Simple A/B tests are free, with your first 1K impressions a month included. Advanced testing is on the Organization plan.
