ABTestly's answer:

Prices are published openly, starting at $99/month with a 14-day free trial, and cost less than Optimizely, VWO or Convert at similar traffic. You also get a real code editor with linting, a sample ratio guard and revenue metrics built in.

ABTestly's answer:

CRO developers, experimentation agencies and in-house product and growth teams at ecommerce and DTC brands who build tests in JavaScript and CSS.

What's the story behind your product?
