Unleash is the enterprise FeatureOps platform that gives teams real-time control over how software behaves in production. Decouple deployment from release, roll out gradually, target users, run experiments, and roll back instantly without redeploying. SDKs evaluate flags locally, so no end-user data is sent to Unleash.
This project is Unleash Open Source: free, self-hosted (AGPL-3.0, PostgreSQL, Docker), no seat limit, with 1 project, 2 environments and up to 5,000 flags.
Unleash Enterprise PAYG costs $75/seat/month with unlimited projects and environments, hosted by us or self-hosted (5-seat minimum), with a 14-day free trial. Custom Enterprise adds an annual contract, a 99.99% uptime commitment, severity-based support and cloud, self-hosted or hybrid deployment.
Built on an open-source foundation with 45M+ Docker pulls, and trusted by Lloyds Banking Group, Prudential, Visa, Samsung, Wayfair and Lenovo.
