About Unleash
What is Unleash?
Unleash is a feature management platform designed for large enterprises. It provides feature flags, kill switches, and audit logs, giving teams control over code written by humans or AI. With Unleash, you can decouple deployments from releases, enabling gradual feature delivery and reducing the blast radius of software releases.
Problem it solves
Traditional software releases are often big-bang events—stressful, risky, and slow. Unleash solves this by allowing teams to release features gradually, target specific users, and instantly roll back if something goes wrong. It also helps manage technical debt by tracking stale flags and improving release governance.
Who it is for
Unleash is built for engineering and product teams at global enterprises like Visa, Lloyds Banking Group, Samsung Ads, and Wayfair. It is ideal for organizations that need enterprise-grade security, compliance (SOC2, GDPR), and scalability. It is not for small projects or startups looking for a basic free tool without enterprise features.
Real use cases
Unleash is used for A/B testing, canary releases, feature toggles, and AI-generated code safety. It also enables teams to release over 100 times a day, as seen at Mercadona Tech, and to maintain compliance in regulated industries like finance and insurance.
Key features
- Feature Flags — Control feature rollout with unlimited flags, targeting, and activation strategies.
- Kill Switches — Instantly turn off problematic features to minimize blast radius.
- Audit Logs — Retain up to 2 years of audit logs for compliance and security.
- Enterprise Security — SSO (SAML 2.0, OpenID Connect), RBAC, and custom project roles.
- Technical Debt Management — Track and remove stale flags with dashboards and notifications.
- Integrations — Slack, Teams, Datadog, Jira, and generic webhooks for automation.
- 25+ SDKs — Support for your favorite language or framework.
