Overview
Reflag is a feature flag management platform for SaaS applications built with TypeScript. It offers a comprehensive set of SDKs to support flag consumption across both frontend and backend codebases. Developers can integrate feature flags in React apps via the React SDK, in Vue apps via the Vue SDK (beta), in general browser-based projects with the Browser SDK, and on the server side with the Node.js SDK (including use in Cloudflare Workers). A CLI is provided to interact with Reflag and generate TypeScript types, helping teams keep their feature definitions in sync with their code. For OpenFeature adopters, Reflag provides browser and Node.js Providers to connect Reflag flag data to the OpenFeature standard, enabling a unified feature-flag experience across environments. The repository is organized as a monorepo with dedicated docs per package and automated publishing via GitHub Actions when changes are merged to main, supporting a smooth versioning and release workflow. Overall, Reflag emphasizes TypeScript-first integration and streamlined flag governance for SaaS products.
