Unleash is an open-source feature management platform for controlling feature flag rollouts across applications via a server and 25+ client/server SDKs. It supports gradual rollouts, A/B testing, kill switches, approval workflows, and can be self-hosted or used as a hosted SaaS.
Use cases
- turn features on and off without redeploying
- gradually roll out a new feature to a percentage of users
- add a kill switch for a risky or AI-generated feature
- run A/B tests with flag variants and user targeting
- manage feature flag technical debt and stale flags
- decouple deployments from releases in CI/CD
- self-host a feature flag service with SDKs in any language
When to choose
- you need a mature, widely adopted open-source feature flag system with many SDKs
- you want self-hosting or data governance with SSO, RBAC, and audit trails
- you need gradual rollouts, canary releases, and instant rollback without redeploys
When to avoid
- you only need a tiny boolean toggle and don't want to run a server
- you need a permissive license for embedding in a closed-source product (AGPL-3.0)
- you want a fully managed service without considering the enterprise pricing tiers
