Optimizely vs Visual Website Optimizer: What are the differences?

Developers describe Optimizely as "Experimentation platform for marketing, product, and engineering teams, with feature flags and personalization". Optimizely is the market leader in digital experience optimization, helping digital leaders and Fortune 100 companies alike optimize their digital products, commerce, and campaigns with a fully featured experimentation platform. On the other hand, Visual Website Optimizer is detailed as "A/B Testing with In-Built Heatmaps". Visual Website Optimizer is an easy to use A/B testing tool that allows marketing professionals to create different versions of their websites and landing pages using a point-and-click editor (no HTML knowledge needed!) and then see which version produces maximum conversion rate or sales.

Optimizely and Visual Website Optimizer belong to "A/B Testing Analytics" category of the tech stack.

Some of the features offered by Optimizely are:

• Visual editor for client-side A/B testing
• Server-side SDKs for Full Stack experimentation
• Mobile app optimization

On the other hand, Visual Website Optimizer provides the following key features:

"Easy to setup, edit variants, & see results" is the primary reason why developers consider Optimizely over the competitors, whereas "Easy setup" was stated as the key factor in picking Visual Website Optimizer.
