OpenFlags

OpenFlags is an open-source, self-hosted feature flag platform for modern JavaScript teams.

It is designed for teams that want the safety of feature flags without adopting a heavy control plane or an expensive hosted dependency. The goal is simple: let developers ship faster, let product teams release with confidence, and keep infrastructure ownership close to the product.

Why teams use it

• Self-hosted by default so data, rollout logic, and operational decisions stay under your control.
• Local evaluation so applications can decide feature state without introducing an extra network hop on every check.
• Percentage rollouts and targeting so launches can be gradual instead of risky.
• JavaScript-first SDKs so integration feels natural in React, Next.js, Vite, Node.js, and related stacks.

Core building blocks

OpenFlags is organized around a few focused parts:

• Server for flag storage, API access, and targeting rules.
• Dashboard for operators, product, and engineering teams to manage rollouts.
• SDKs for evaluating flags inside applications.
• Docs for onboarding, implementation references, and product-facing guidance.

Who it is for

OpenFlags is a good fit when your team wants:

• safer releases without platform sprawl,
• a transparent codebase that can be self-hosted,
• a feature flag system that feels natural in a JavaScript monorepo,
• a clear path from product idea to controlled rollout.
