Built for engineers
tired of shipping opinions.

Most experimentation platforms are built to sell to marketing teams, not to be used by engineers. The product-led screenshots are gorgeous. The developer experience is an afterthought.

A vs B is the other way around. Built in the open. TypeScript-first, SCSS-first, SDK-first. Variations live in control.ts and variant.ts, not in a WYSIWYG. The SDKs ship their own types. The CLI is a first-class citizen. Every integration has a documented webhook.

Bayesian and Frequentist stats — both, on day one — because the choice matters. Bayesian for low-to-mid traffic experiments, where you want to peek whenever you want. Frequentist for high-traffic clients who want the textbook p-value and confidence interval. You pick at the org, project, or experiment level.
