Intent
I need it when
Ship features safely with controlled rollouts and kill switches without redeploying
OpenFlags enables progressive delivery through percentage rollouts and targeted activation, allowing teams to launch features to a controlled slice of users and roll back instantly via dashboard without code redeploy
Run a lightweight feature flag system without platform sprawl or enterprise overhead
OpenFlags is designed as a focused, open-source platform with clear separation between server, dashboard, SDKs, and docs, avoiding heavy control plane complexity while remaining fully customizable
Integrate feature flags naturally into JavaScript-first development workflows
OpenFlags provides type-safe SDKs built for React, Next.js, Vite, Node.js, and Bun with simple REST API and monorepo-friendly setup that feels native to modern JavaScript stacks
Keep infrastructure ownership and data control within the organization
OpenFlags is self-hosted by default, allowing teams to run the control plane, flag storage, and rollout logic inside their own infrastructure rather than depending on external vendors
Drop
Not a fit when
- Teams requiring a fully managed SaaS solution with vendor support and uptime guarantees
- Organizations without JavaScript/TypeScript expertise or infrastructure to self-host
- Projects needing enterprise feature flag platforms with advanced analytics and A/B testing
- Teams requiring multi-language SDK support beyond JavaScript ecosystem
- Companies with strict compliance requirements that prohibit open-source dependencies in production
