About
SignaKit is a feature flags, A/B testing, and experimentation platform for engineering teams that need full control over software releases without per-seat pricing or vendor lock-in. Flags are evaluated locally inside the application process using a cached configuration served from AWS CloudFront, producing sub-millisecond evaluation with no network roundtrip on the hot path — bucketing is deterministic via MurmurHash3, so the same user always receives the same variant across sessions and devices. Teams can create boolean and multivariate flags with percentage rollouts, audience targeting by any user attribute, and instant kill switches for emergency rollbacks. Built-in A/B testing tracks statistical significance with configurable experiment snapshot intervals, and multi-armed bandit optimization automatically shifts traffic toward the winning variant as results accumulate — included on every plan, including Free.

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.
