Why Look for a Convert Alternative?

Complex Pricing Structure

Convert's pricing is based on monthly tested users with different tiers and annual vs. monthly options, making it difficult to predict costs.

Usage Limits

Convert limits your monthly tested users, requiring an upgrade when you exceed your plan's limit, which can get expensive quickly.

Feature Limitations in Lower Tiers

Many essential features like multivariate testing are locked behind higher pricing tiers, forcing you to upgrade.

Script Size and Page Performance

Heavier testing tools can slow down your website, potentially impacting user experience and core web vitals scores.
