About
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. Experiments 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 rather than one inferred number, so results stay auditable. Confidence intervals are shown with the sample size, no winner is declared before significance, and sample ratio mismatch is detected and flagged.
Three statistics engines: frequentist on every plan, sequential and Bayesian from Pro upwards. Also a speed guardrail comparing p75 LCP against control.
Pricing is published: $99 a month at 50,000 tracked users, $249 at 200,000, $549 at 500,000, with a 14-day trial on monthly plans.

About
GrowthBook is an open source feature-flagging and experimentation platform built to help teams release code confidently and measure the impact of product changes using their own data. It enables the creation and management of feature flags of various types (Boolean, number, string, JSON) with targeting rules, percentage roll-outs, safe ramp-ups, and experiment assignment. The platform is warehouse-native, allowing you to connect your data where it already lives (SQL data warehouses, Mixpanel, Google Analytics, and more) and run experiments and analyses without sending raw user-level PII to a third-party service. It supports modular usage; you can adopt just feature flagging, just experiment analysis, or both together. Key capabilities include: high-performance lightweight SDKs (enabling billions of feature lookups per day), a visual editor for no-code AB tests, and experiment reporting with advanced statistical methods.
