Feature flags that are oss, private, secure, and ready for the most complex setups out of the box. Built for enterprises.
Categories:
Unleash is an open-source feature management platform that enables teams to safely roll out features using flags, kill switches, and progressive delivery strategies, primarily for enterprise development teams.
🚀 Overview
Unleash solves key challenges in software delivery like costly downtime (average $400k/hour), slowed innovation from infrequent high-stakes releases, and unreliable home-grown feature flag tools that increase maintenance and reduce velocity.
It provides intuitive feature flags, governance, and security to enable faster, safer releases—decoupling deployment from release for continuous delivery.
Built for developers who need great DevEx and enterprises requiring compliance (SOC2, ISO27001, FedRAMP), auditability, and scalability. Started in 2014 by Ivar Conradi Østhus as the leading open-source solution, now with 13k+ GitHub stars and used by Lloyds Banking Group, Wayfair, Prudential, and more.
✨ Key Features
- Rollout strategies (gradual, canary, A/B testing), instant rollback, kill switches to reduce release risks and handle high-traffic events.
- Enterprise governance: RBAC, audit logs, change requests, SAML/SSO, air-gapped support.
- Adminless onboarding, 15+ official SDKs for any stack (Go, Java, etc.), experimentation tools.
- Optional: Impact metrics (beta), advanced analytics.
🛠 Tech Stack
- Frontend: React, TypeScript
- Backend: Node.js, TypeScript
- Database: PostgreSQL
- Auth: Custom / SAML
- Hosting: Docker self-host, Unleash Cloud, or partners
