    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.

  • note_icon

    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.

  • note_icon

    Auditing and Productivity

    Enterprises can easily audit “who releases what, when, and to whom” without getting in the way of developer productivity.

  • note_icon

    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

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.

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.
