Convert's pricing is based on monthly tested users with different tiers and annual vs. monthly options, making it difficult to predict costs.
Convert limits your monthly tested users, requiring an upgrade when you exceed your plan's limit, which can get expensive quickly.
Many essential features like multivariate testing are locked behind higher pricing tiers, forcing you to upgrade.
Heavier testing tools can slow down your website, potentially impacting user experience and core web vitals scores.
At just 5.4KB and served on a CDN, Stellar's pure JS script is 25x smaller than competitors like VWO or AB Tasty. With minimal dependencies and a fixed size regardless of test count, it preserves your website's speed, Core Web Vitals, user experience, and SEO performance.
