Feature flag platform enabling safe, incremental releases
Unleash lets teams control feature rollouts, run canary releases, and test in production with an API‑first system and 15+ official SDKs, all self‑hostable via Docker.
Unleash is a feature‑flag system designed for development teams that need precise control over how new functionality reaches users. By decoupling deployment from release, it lets engineers ship code continuously while safely toggling features on or off, performing canary rollouts, and conducting A/B tests without additional deployments.
You can spin up a local instance in minutes using Docker Compose, then connect any of the 15+ official SDKs (Go, Java, Node.js, PHP, Python, Ruby, etc.) to start toggling flags. For production, Unleash can be self‑hosted on any server or cloud provider, with optional Edge scaling for high‑traffic front‑ends. Enterprises can also evaluate the hosted Unleash Enterprise trial, which adds RBAC, SSO, and advanced segmentation.
When teams consider Unleash, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Canary release of a new UI
Expose the UI to a small user segment, monitor performance, and roll back instantly if issues arise.
Beta feature toggle for power users
Enable experimental functionality only for selected users without redeploying the application.
Instant kill‑switch for a faulty feature
Disable a problematic flag across all environments in seconds, preventing user impact.
A/B testing of pricing page
Serve two variants to different user groups and collect conversion data via webhook integrations.
Unleash offers official SDKs for Go, Java, Node.js, PHP, Python, and Ruby, plus numerous community SDKs for other languages.
Clone the repository, run `docker compose up -d`, then open `localhost:4242` and log in with the default admin credentials.
Yes, Unleash Enterprise provides a hosted trial and cloud instances with the full feature set.
Absolutely. Deploy the Docker image or run the Node.js application on any server, with guides for Heroku, DigitalOcean, and more.
The platform follows privacy‑by‑design principles, offers audit logs, enforces strict HTTPS‑only mode, and Enterprise adds RBAC, SSO, and SCIM.
