Unleash
Unleash — Feature Management Platform / Feature Flags for Large Enterprise
Unleash is a FeatureOps control plane that lets teams release, experiment on, and kill features in production in real time without redeploys. It addresses the need for runtime control over how software behaves, supporting progressive rollouts, instant rollback, kill switches, and release templates across the full change lifecycle. The platform can be run in Unleash's cloud or self-hosted on your own infrastructure, with flag evaluation happening locally inside your applications.
Core capabilities include feature flag management, A/B/n testing with flag variants, user segmentation, custom activation strategies, and lifecycle management for tracking stale flags. It offers 25+ SDKs covering frontend and backend frameworks, plus integrations with Slack, Teams, Datadog, and Jira, along with Admin, Frontend, and Client APIs and generic webhooks. Security features include SSO with SAML 2.0 or OpenID Connect, role-based access control, audit logs, and SOC2 Type II and GDPR compliance. Enterprise Edge provides distributed flag evaluation across regions.
Unleash targets enterprises with security, compliance, and data residency requirements, as well as development teams seeking faster release workflows. It is packaged as a seat-based Pay-As-You-Go plan with a 14-day trial requiring no credit card, and a Custom Enterprise edition with guided onboarding and annual contracts available in cloud, self-hosted, or hybrid configurations. An open-source version is also available on GitHub.
