Description
ABTestly is a robust A/B testing solution designed for teams that prefer to implement experiments through code rather than a graphical interface.
Each variation is crafted using authentic JavaScript and CSS, ensuring that experiments are integrated directly into your code repository and undergo the same rigorous review process as other code modifications. The platform maintains a lightweight runtime of approximately 31 KB when gzipped, and it prevents visitors from experiencing a flash of the control version by holding the page until the variation is fully applied.
Instead of relying on a single inferred number, ABTestly meticulously tracks assignment, exposure, and conversion as three distinct events on a precise ledger, enhancing the auditability of results. It provides clear confidence intervals along with the sample size, avoids premature declarations of winning variations, and identifies any sample ratio mismatches, alerting users to potential issues.
The platform features three statistical engines: frequentist analysis is available for all plans, while sequential and Bayesian methods are reserved for Pro plans and above. Additionally, it includes a speed guardrail that compares the 75th percentile Largest Contentful Paint (LCP) against the control group, ensuring optimal performance metrics.
Transparent pricing is available, with plans starting at $99 per month for up to 50,000 tracked users, $249 for 200,000 users, and $549 for up to 500,000 users, all of which come with a 14-day trial for monthly subscriptions to allow teams to evaluate the service effectively.
