Detailed Analysis

1. A Suite or a Focused Tool

VWO sells several products side by side, including web experimentation, personalization, behavior analytics (heatmaps and recordings) and user feedback, as its pricing page shows. If you need all of those, a suite can make sense.

Zyro is narrower. It traces each sale to the ad or channel that brought it, runs A/B tests and offers, and tells you each result in one plain sentence. On Shopify you install the app; anywhere else you paste one snippet.

2. Bandits and Statistics

VWO offers multi-armed bandit testing, and its SmartStats engine is Bayesian (see VWO's SmartStats article). Check VWO's plans for which tier includes which feature.

Zyro also reports results with Bayesian statistics, as the chance each version beats your original, and runs bandit tests (Thompson sampling) on the Growth and Scale plans, so less of your traffic goes to losing versions.
