What is 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. Configuration is served from Cloudflare's edge in more than 300 cities, so the variant is resolved before the page paints and there is no flicker between control and variation. The runtime is about 31 KB gzipped.

Experiments live in your repository and go through the same review as any other change. Assignment, exposure and conversion are recorded as three separate events on an exact ledger rather than one inferred number, which keeps results auditable.

Three statistics engines are available: frequentist on every plan, with sequential and Bayesian from the Pro plan upwards. Other features include sample ratio mismatch detection, a speed guardrail that compares p75 LCP against the control, segment filters, scheduled starts and ends, and mutual exclusion groups on higher plans.

Pricing is published rather than quoted: 99 USD a month for 50,000 tracked users, 249 for 200,000 and 549 for 500,000, with a 14-day trial on monthly plans.
