Easily configure which feature flags are enabled for which users. Unleash has built-in default strategies like Progress Rollout that make getting started easy. Custom constraints allow targeting feature rollouts based on any attribute you can imagine like geo, customer type, or arbitrary telemetry.
Boost Developer Productivity with Secure, Compliant Feature Management
As the largest open-source feature flag platform, Unleash gives developers tools to be efficient and love their jobs, while enterprises get market-leading data governance, security, and compliance controls.

Why Developers & Enterprises love Unleash
Our Mission
Unleash is on a mission to make life easier for developers while enabling enterprises to increase their software release velocity without reducing security, compliance, or data governance.
Decoupling Code Deployments from Feature Releases
By decoupling code deployments from feature releases, Unleash saves developers from merge conflict hell, long testing cycles that can never uncover all potential edge cases, and lack of insights into how users interact with new features.
Auditing and Productivity
Enterprises can easily audit “who releases what, when, and to whom” without getting in the way of developer productivity.
Real-Time Feedback and Instant Rollbacks
Developers can get real-time feedback on how new features are performing with testing happening in the best possible way, with a limited set of real users and data. If anything goes wrong, rollbacks happen instantly with the click of a button.
Flexible Architecture
Coupled with Unleash's flexible architecture that can run entirely within a customer's data center or cloud, Unleash provides the best of both worlds: intuitive tools that both the development and security/compliance teams love.
Reduce risk associated with releasing new features
Drive innovation by streamlining software releases
Unleash Signals enable you to take in telemetry from any system capable of emitting JSON metrics. Unleash Actions allow you to take those signals and automatically adjust rollout strategies, initiate rollbacks, or enable kill switches.
Increase revenue by optimizing user experience
Create experiment variants that decide which users get access to which version of an experiment. Variants facilitate A/B testing and experimentation by letting you create controlled and measurable experiments.
Improve security and compliance by protecting data
Run Unleash as a self-hosted service in your data center, or let us host it as a single-tenant private instance. In either case, no end-user data ever leaves your environment.
Why Unleash
What use cases does Unleash support?
Progressive Rollouts
Test with a targeted group of users before going live everywhere to eliminate the risk of rolling out new features.
Rollback
Instantly roll back misbehaving features to eliminate downtime and improve user experience.
A/B/n Testing
Make data-driven decisions on which features are driving the right behaviors.
Kill Switches
Easily implement operational flags like Kill Switches so that you can instantly respond in break-glass scenarios.
Trunk-based development
Move away from high-stakes all-or-nothing releases.
Fed Ramp, SOC 2, ISO 27001 + Air-gapped environments
Meet the strictest security and compliance requirements with Unleash’s self-hosting, strict change controls, and audit logs.
Unleash ranked as top Feature Management Software on G2
We serve the needs of some of the largest and most security-conscious organizations in the world, but we were also rated the “Easiest Feature Management system to use” by G2.
"We flipped the most important flag we could when we went from our in-house system to Unleash. Right away we found that it was scalable, highly performant, resilient out of the box. And Unleash ended up being 1/3 the cost of our homegrown feature flag solution, while also improving the reliability and scalability of our platform."
