1. How You Buy It

When we checked in October 2026, Optimizely's pricing page said every plan is individually packaged and asked visitors to request a demo. That suits large teams with a buying process.

Zyro publishes its prices. Start on the Free plan with revenue attribution, move to Starter for A/B tests and live offers, or to Growth and Scale for bandit tests and more tracked visitors. On Shopify you install the app; anywhere else you paste one snippet.

2. Checking Results Early

Optimizely's Stats Engine uses sequential testing, which is built so you can watch results while a test runs (see Optimizely's statistics docs). It also offers multi-armed bandit optimizations.

Zyro takes a Bayesian approach: every result is the chance a version beats your original, and Zyro waits for enough visitors and sales before it pauses a losing version. On the Growth and Scale plans, bandit tests shift more traffic to the better version as the test runs.
