About FF4J
Feature flags for java made easy. Enable. and disable features at runtime - no deployment. Implement multiple paths in your code with predicates evaluated dynamically (if/then/else). Enable features not only with flag values but also drive access with roles and groups (Canary Release). Different frameworks supported starting by Spring Security. Implement custom predicates (Strategy Pattern) to evaluate if a feature is enabled. Some are provided out of the box: White/Black lists ,Time based, Expression based. Connect external source like a Drools rule engine. Keep your code clean and readable: Avoid nested if statements but use annotations. Thanks to Spring AOP target implementation is pick at runtime, and thus driven by feature statuses. For each features execution, ff4j evaluates the predicate therefore it's possible to collect and record events, metrics to compute nice dashboards or draw curves for features usage over time.
Flagship.io
Flagship.io is a feature flagging platform for modern engineering and product teams that eliminates the risks of future releases by separating code deployments from these releases. With Flagship, you can accelerate development cycles and ship anywhere anytime, even on Friday nights.
With Flagship, we push the concept of feature flags to the next level giving you full control over the release process. With Flagship, you can:
- Switch features on or off through remote config.
- Separate code deployments from future releases, allowing engineering teams to deploy code at their pace while enabling product teams to release these features when they’re ready.
- Automatically roll-out your features gradually to monitor performance in line with their associated KPIs and gather feedback from your most relevant users.
- Roll back any feature should any issues arise while testing in production while your team analyzes the problem.
- Segment users by granting access to a feature

Flagsmith
Flagsmith is a fully supported open source Feature Flag, Remote Config, and A/B testing service. Use our hosted API, deploy to your own private cloud, or run on-premise.
Flagsmith makes it easy to create and manage features flags across web, mobile, and server side applications. Just wrap a section of code with a flag, and then use Flagsmith to toggle that feature on or off for different environments, users or user segments.
Feature flags - Release features with confidence through phased rollouts.
Remote config - Easily toggle individual features on and off, and make changes without deploying new code.
A/B and Multivariate Testing - Use segments to run A/B and multivariate tests on new features. With segments, you can also introduce beta programs to get early user feedback.
Organization Management - Organizations, projects, and roles for team members help keep your deployment organized.
Integrations - Easily enhance Flagsmith with your favourite tools.

Togglz
Togglz is an implementation of the Feature Toggles pattern for Java. Feature Toggles are a very common agile development practices in the context of continuous deployment and delivery. The basic idea is to associate a toggle with each new feature you are working on. This allows you to enable or disable these features at application runtime, even for individual users. Feature Toggles are very useful especially in the context of agile development practices and are used by big sites like Flickr. The basic idea is to have a configuration file that defines a bunch of toggles for various features you have pending. The running application then uses these toggles in order to decide whether or not to show the new feature. As this toggle is disabled by default you can safely deploy the application to the production servers even if the feature is not completely finished and tested. If the feature implementation is complete you can enable it in the production system at any point in time.
