OpenFlags

OpenFlags is a lightweight, developer-first feature flagging platform designed to give teams full control over their release cycle without the "enterprise tax" or external dependencies. Built with Bun and TypeScript, it focuses on extreme performance, local evaluation, and privacy.

While many feature flag services introduce latency or high costs, OpenFlags is designed to stay out of the way. It allows you to ship faster, de-risk deployments, and manage progressive rollouts from your own infrastructure.

Key Features: • 0ms Local Latency: Evaluate flags locally within your application for predictable, lightning-fast performance. • Self-Hosted & Privacy-First: Keep your data, audit logs, and flag configurations on your own servers. • Type-Safe SDKs: Native support for modern JavaScript stacks (Bun, Node, React, Next.js, Vite). • Progressive Delivery: Release features to a percentage of users or specific segments to minimize blast radius. • Modern Stack: Powered by Bun for a high-performance API and a clean React-based dashboard. • Developer Ergonomics: Simple REST API and monorepo-friendly architecture that fits into existing CI/CD workflows.

Why Choose OpenFlags? If you are looking for a transparent, open-source alternative to LaunchDarkly, Flagsmith, or Unleash that doesn't compromise on speed or developer experience, OpenFlags is built for you.
