Type-Safe Feature Flags and Flexible Remote Config service designed for developers building modern web apps.
🚀 Overview
Abby is an open-source, type-safe feature flag and remote config service that simplifies managing feature deployments safely across environments. It solves the problem of complex feature rollouts by providing typed SDKs, A/B testing, and environment-specific configs, reducing downtime and enabling quick iterations without redeploys.
Built for engineering teams at startups and enterprises using React and Next.js, Abby ensures stability with built-in fallbacks and DevTools for debugging. We built it to make feature flagging accessible, performant, and fully integrated with modern frameworks.
