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.

Userback
Userback is the leading user feedback and bug tracking solution for software teams looking to understand users and build better products.
With Userback, you can collect metadata-enriched visual feedback and gain deep insights into your user's sentiment and behavior with in-app surveys like NPS, CES, and CSAT metrics. Add deep context to any piece of feedback via full session replay features.
Create user segments and track every user from the moment they log in. Survey only the cohorts that are important to you and understand your user experiences throughout the entire lifecycle from trial to churn.
Wrap it all up with branded feature portals, and public roadmaps, and a centralized location for all your feedback to reduce feedback overhead by 70% and increase feedback closure times by 10X.

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.

waiting
waiting is a small library for waiting for stuff to happen. It basically waits for a function to return True, in various modes. Waiting is compatible with flux for simulated timelines. The most basic usage is when you have a function you want to wait for. Waiting forever is very simple. If your predicate returns a value, it will be returned as the result of wait(). A timeout parameter can also be specified. When a timeout expires without the predicate being fulfilled, an exception is thrown. Sleeping polls the predicate at a certain interval (by default 1 second). The interval can be changed with the sleep_seconds argument. When waiting for multiple predicates, waiting provides two simple facilities to help aggregate them, any and all. They resemble Python’s built-in any() and all(), except that they don’t call a predicate once it has been satisfied (this is useful when the predicates are inefficient and take time to complete).

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.
