Audience

Software engineering and CRO teams at ecommerce and SaaS companies who write their own test variations in code, and agencies running experiments for client sites.

About ABTestly

ABTestly is an A/B testing platform for teams that ship experiments in code rather than through a visual editor.

You write each variation as real JavaScript and CSS. Experiments live in your repository and go through the same review as any other change. The runtime is about 31 KB gzipped, and the page is held until the variation is applied, so visitors do not see the control flash first.

Assignment, exposure and conversion are recorded as three separate events on an exact ledger rather than one inferred number, so results stay auditable. Confidence intervals are shown with the sample size, no winner is declared before significance, and sample ratio mismatch is detected and flagged.

Three statistics engines: frequentist on every plan, sequential and Bayesian from Pro upwards. Also a speed guardrail comparing p75 LCP against control.

Pricing is published: $99 a month at 50,000 tracked users, $249 at 200,000, $549 at 500,000, with a 14-day trial on monthly plans.
