What is Unleash?
Feature management lets you turn new features on/off in production with no need for redeployment. A software development best practice for releasing and validating new features.
Faster experiments Fewer procedures
Safe and easy gradual rollouts Test and try out new features confidently. Gradual rollouts allow you to mitigate risks by enabling new features to 1% of users and then expanding.
Measure new feature performance Validate how every new feature performs. A/B test alternatives on real users to gain real insight on what delivers best results.
Accurate user targeting Enable new features on any subset of your user base, by segmenting features to any attribute of your application.

Said about Unleash as an alternative
