Unleash
Open-source FeatureOps platform for feature flags, progressive delivery, experimentation, and kill switches that enterprises can self-host or run in Unleash cloud. Unleash raised a $35 million Series B in 2026, led by One Peak.
Engineering teams that want feature flags with progressive rollouts, experimentation, and a self-host or EU-friendly cloud path without giving up governance.
Teams that only need a tiny toggle CDN, or buyers who want the deepest managed commercial stats suite first and will not self-host.
Verdict
Unleash is a good fit when the bottleneck is controlling releases and AI-driven changes in production without another black-box silo. Practitioners like the open-source core; buyers chasing the thickest managed experimentation analytics may still prefer Statsig.
