What is Unleash?
Unleash is a feature management platform that lets enterprises control how software behaves in production through feature flags, enabling releases, experiments, and kill switches in real time without redeploys. Built on the largest open-source feature flag project, Unleash can run in its cloud or be self-hosted on an organization's own infrastructure, with flag evaluation happening locally inside applications.
Key Features
- Feature flags and kill switches: Unleash lets teams ship changes to production behind a flag and roll them out or back on their own terms without a redeploy, including instant rollback and kill switches for critical changes.
- Progressive rollouts and release templates: Releases can be staged gradually and standardized through release templates, giving teams repeatable control over how changes reach users.
- Experimentation: The platform supports A/B testing and fast iteration, as shown in its own example of toggling a homepage call-to-action variant via the
isEnabledcheck. - 25+ SDKs and AI coding tool support: Unleash provides SDKs across more than 25 languages and frameworks and supports AI coding tools, fitting into trunk-based development workflows.
- Self-hosting and data residency: The entire platform can be self-hosted, flag evaluation runs locally inside applications, and no data leaves the organization's infrastructure, with no vendor lock-in since the code can be audited, forked, and run indefinitely.
- Enterprise governance: Audit logs, security and role-based access control (RBAC), compliance and data residency controls, and SOC2, ISO27001, FedRAMP-ready, and GDPR alignment support security-conscious organizations.
- Open-source foundation: Every line of code is exercised by a large community before reaching enterprise deployments, backed by 13K+ GitHub stars, 45M+ Docker pulls, and 100K+ monthly active users.
- Production scale: Unleash reports 7.5T+ flag evaluations daily and over 10 years of maturity, and it was the first feature flag platform on the ThoughtWorks Tech Radar.
Use Cases
- Enterprise release management: Security-conscious organizations use Unleash to give developers freedom to move fast with trunk-based development while meeting audit, compliance, and data residency requirements.
- AI feature control: Teams shipping AI-driven functionality use Unleash as an AI kill switch they control end to end, releasing, experimenting with, and killing anything AI ships in real time.
- Progressive delivery and rollback: Engineering teams roll out changes gradually behind flags and roll back instantly when issues appear, avoiding redeploys during incidents.
- A/B testing and experimentation: Product and engineering teams run experiments and iterate quickly by toggling behavior for segments of users through flag checks in application code.
- Incident prevention: Organizations responding to postmortems from major outages add feature flags and kill switches to critical changes to close the runtime control gap.
Who It Is For
Unleash targets enterprises and engineering teams—developers practicing trunk-based development, platform and DevOps teams, and security and compliance stakeholders—that need runtime control over production software. It solves the problem of shipping changes safely at scale by separating deployment from release, while satisfying enterprise requirements for self-hosting, audit logs, RBAC, and data residency.
Pricing
Unleash offers a free trial with no credit card required and simple pricing with no hidden costs, alongside a pay-as-you-go Enterprise option described as the easiest way to get started without yearly commitments. Specific price figures are not stated in the source material.
Frequently Asked Questions
What is Unleash used for?
Unleash is a feature management platform used to control how software behaves in production. Teams use Unleash to release changes behind feature flags, run experiments, perform progressive rollouts, and kill problematic features in real time without redeploying.
Can Unleash be self-hosted?
Yes. Unleash can run in the vendor's cloud or be self-hosted entirely on an organization's own infrastructure. Flag evaluation happens locally inside applications, so no data leaves the organization's infrastructure, and there is no vendor lock-in.
Is Unleash open source?
Unleash is built on the world's largest open-source feature flag project. The code can be audited, forked, and run indefinitely, and the project has 13K+ GitHub stars and 45M+ Docker pulls.
What compliance and security standards does Unleash support?
Unleash states alignment with SOC2, ISO27001, FedRAMP-ready requirements, and GDPR. The platform also provides audit logs, security and role-based access control, and compliance and data residency controls for enterprise governance.
Who should use Unleash?
Unleash is designed for large enterprises and engineering teams that need runtime control over production changes. It suits organizations practicing trunk-based development, teams running experiments, and security-conscious enterprises requiring self-hosting, audit logs, and data residency.
