Unleash

Open-source self-hosted feature flag leader (Apache-2.0).

By Bricks Software AS · Founded 2014 · Oslo, Norway · private

Unleash is the open-source self-hosted feature flag leader, started as a Finn.no internal project in 2014 and commercialized under Bricks Software in 2019. The product is Apache-2.0 licensed with a paid Pro and Enterprise tier on top of the OSS core. Strengths: most mature self-hosted deployment in the category, true OSS heritage with active community (10K+ GitHub stars), strong fit for regulated industries needing air-gap deployment, and predictable seat-based pricing on Enterprise. Trade-offs: SaaS UX feels less polished than LaunchDarkly or Statsig, experimentation features thinner than category leaders, and the self-hosted operational burden is real, your platform team carries it.

Best for

Worst for

Teams wanting the cleanest SaaS UX (LaunchDarkly or Statsig better), product teams needing bundled experimentation (Statsig or PostHog better), or small teams without platform-engineering capacity (ConfigCat simpler).
