Aggregated, with sample sizes. We use whichever review platform has data.
Optimizely and VWO are both serious A/B testing platforms, but they serve different market segments. Optimizely (formerly Episerver) is enterprise-grade — custom pricing, dedicated onboarding, and a feature set built for large organizations running hundreds of concurrent experiments. VWO takes a more accessible approach with a free trial, visible pricing starting around $200+/month, and a product that's approachable for mid-market teams.
Both platforms support A/B, multivariate, and split URL testing with advanced targeting and segmentation. Optimizely's edge is in its experimentation depth — feature flagging, server-side testing, and its data platform integrations. VWO's edge is in accessibility and visual editor quality, making it faster to deploy tests without engineering support.
