Welcome to ABMeter

Your experiment data lives in ABMeter. Connect your AI and it reads the results, flags what changed, and recommends whether to ship. From raw statistics to a clear next step, in one conversation.

AI assists with experiment management, but destructive operations always require human approval. No accidental production changes, ever.

One platform for events, typed metrics, formulas, and statistical analysis. Declare event schemas once, define metrics as reusable formulas, run experiments without stitching together extra tools.

ABMeter computes z-tests, p-values, and 95% confidence intervals automatically for every metric: conversion rates, revenue per user, or any custom formula. Sound statistics out of the box, no expertise required.

Three first-class ways to integrate: REST API, Ruby SDK, and MCP server. The API is the platform. Every feature is scriptable, automatable, and reviewable in code.

Integrate once against typed parameter names. Create and modify experiments later without touching code. Your integration stays constant while experiments evolve.

Prevent experiment conflicts with space-level isolation. Within a space, users are never assigned to two active experiments at once, and flexible audience rules let you target any slice of traffic.

No server roundtrips. The SDK evaluates locally using cached configs for instant variant assignment, so your app stays fast no matter how many experiments you run.
