ABTestly is built for people who write tests in code. Variants resolve at the edge before the page paints. Every result comes from counted events. You choose the stats engine for each test (Frequentist, Sequential or Bayesian) instead of accepting a black-box verdict.
Prices are published openly, starting at $99/month with a 14-day free trial, and cost less than Optimizely, VWO or Convert at similar traffic. You also get a real code editor with linting, a sample ratio guard and revenue metrics built in.
CRO developers, experimentation agencies and in-house product and growth teams at ecommerce and DTC brands who build tests in JavaScript and CSS.
ABTestly was built by experimentation developers frustrated by visual editors, flicker and opaque stats in existing tools, so they made the platform they wanted to build tests in.
TypeScript, the Cloudflare edge network, Clerk for authentication, Paddle for billing and Mintlify for docs.
