Unleash

13,793894

Unleash is an open-source feature management platform, and a self-hosted alternative to LaunchDarkly. It controls feature flags through activation strategies — gradual rollouts, user targeting, A/B tests — with SDK evaluation happening locally for low latency and privacy. It includes environments, approval workflows, audit logs, and a metrics view of flag exposure.
