About VWO
VWO is an A/B Testing & CRO tool built for mid-market CRO teams. The strengths show up in two places — All-in-one CRO + heatmaps + replay, and visual editor for non-technical users. The product centres on A/B + multivariate testing and Heatmaps + session replay — everything else is scaffolding around those. There's a free plan to explore before paying, with paid upgrades when you need them. The best mid-market all-in-one CRO suite.

Frequently asked questions
What people usually want to know before signing up for VWO.
Does VWO include session replay?
Yes, on all paid plans.
Is the free plan enough?
For small sites running occasional tests, yes.
Does the editor cause page flicker or hurt Core Web Vitals?
Modern async-rendering engines keep flicker under 100ms. Older synchronous snippets can add 300ms+ to LCP — test before you ship.
How much traffic do I need to run a test?
Roughly 1,000 conversions per variant per week for a 10% MDE at 95% confidence. Below that, tests take longer than the lifetime of the feature.
Is server-side testing worth the extra work?
For logged-in features and pricing changes, yes — it's the only way to test without exposing your experiment architecture to the client.
Bottom line
Should you use VWO?
The best mid-market all-in-one CRO suite. Enterprise should pick Optimizely; developer-first teams, Statsig.
