ABtesting.ai vs Apertio
Both stand on conversion rate optimisation tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan APIWeb
ABtesting.ai is suited to landing-page owners who want automated experiment suggestions and a free first experiment. Look at a paid plan if you need more than one experiment, more AI-generated variations or higher monthly visitor capacity.
