Abby

Open-source, fully typed feature flagging and remote config for React/Next.js.

PlatformWebfreemiumglobal

An open-source, self-hostable platform that provides fully typed feature flags and remote configuration for React and Next.js applications. It reduces runtime errors from untyped flag SDKs by offering typed SDKs, multi-environment testing, contextual debugging and built-in fallbacks, so React and Next.js development teams can manage feature flags and A/B tests safely across environments; not intended for non‑JavaScript/TypeScript stacks.
