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.

About
Spar is an AI conversion rate optimization (CRO) and A/B testing platform for Shopify, broader ecommerce, and SaaS teams. It profiles any storefront, grounds recommendations in your funnel data, behavior signals, reviews, public opinion, and brand context, then turns specific friction points into prioritized, test-ready A/B variations, each citing the evidence it came from. Spar runs and measures its own tests using sequential statistics, flagging a winner once a variation reaches 95% probability of being best. Variants are scoped JavaScript, so your theme and app code stay untouched. It works alongside other experiment and task management platforms. Nothing ships without your approval.
