ABTestly is A/B testing for teams that write their variations in code rather than in a visual editor. Variations are real JavaScript and CSS. They 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, so results stay auditable.

Could you build this?
Partial While injecting variations via JS is straightforward, building an ultra-lightweight (31KB) zero-flicker client runtime paired with robust, auditable statistical significance engines (like Bayesian or sequential testing) is non-trivial.
What it would actually take: Requires an edge-distributed JS script (Cloudflare Workers/AWS CloudFront) designed to mutate DOM before paint (anti-flicker) while maintaining sub-50ms latency, paired with a statistical analysis backend implementing CUPED variance reduction and multi-armed bandit or sequential hypothesis testing. The primary difficulty is ensuring statistical correctness under traffic anomalies and maintaining minimal latency without visual layout shifts. Requires strong statistics and web performance engineering expertise.
