Togglz is an open-source implementation of the Feature Toggles pattern for the Java platform, letting developers associate toggles with features and enable or disable them at runtime, even per user. It offers a modular design with integrations for Spring, CDI, JSF, and Servlet environments, plus an embedded admin console and pluggable activation strategies and state repositories.

Use cases

• toggle features on and off at runtime in a Java application
• roll out a new feature gradually to a percentage of users
• enable unfinished features only for internal beta testers in production
• kill a buggy feature instantly without redeploying
• manage feature flags from an admin console in a Spring Boot app
• implement dark launches and continuous deployment with feature toggles

When to choose

• you are building a Java/JVM application and want a mature, battle-tested feature toggle library
• you need fine-grained activation strategies like gradual rollout, username lists, or release dates
• you want an embedded admin console and simple enum-based feature declarations
• you use Spring, CDI, or JSF and want first-class framework integration

When to avoid

• your stack is not on the JVM (consider Unleash, LaunchDarkly, or Flagsmith instead)
• you need a hosted SaaS feature flag service with dashboards and analytics
• you only need simple environment-based configuration toggles rather than runtime feature management
