## About

Unleash is a Norwegian open-source feature management platform founded in 2015 by Ivar Østhus at Finn.no and later spun out as an independent company. The platform is one of the oldest open-source feature flag systems and has a mature SDK ecosystem covering 20+ languages. Unleash provides feature toggles with strategies (gradual rollout, user segments, A/B testing), an admin UI, and enterprise features like SSO and audit logs. The hosted cloud version (Unleash Enterprise) competes directly with LaunchDarkly but at a significantly lower price point. Unleash raised $14M in Series A funding in 2022 and is used by companies including Adobe, Cisco, and Trivago.
