Optimizely has recently renamed the latest version of Full Stack to Optimizely Feature Experimentation. This documentation is for Feature Experimentation.
Feature Experimentation is the default for new projects created after February 2021. Feature Experimentation projects:
For documentation on Full Stack (legacy) projects created before February 2021 or have selected Use Legacy Experience on project creation, refer to the Full Stack portion of our documentation by selecting Full Stack Experimentation in the drop-down menu above.
For more information, refer to the article on Optimizely Feature Experimentation application migration.
Optimizely Feature Experimentation is a feature flagging and experimentation platform for websites, mobile apps, chatbots, APIs, smart devices and anything else with a network connection.
You can deploy code behind feature flags, experiment with A/B tests and use percentage deliveries to roll out or roll back flags immediately. This functionality is available with microsecond performance impact via easy-to-use, open-source SDKs.
Optimizely Rollouts is the free plan for Optimizely Feature Experimentation, designed for startups and teams looking to get started. It comes with free feature flags and the ability to run one A/B test simultaneously.

Our SDKs are built for developers and support:
- Feature flags and experimentation – Our SDK framework natively integrates feature flags and product experimentation, so you can roll features out, roll them back and continuously iterate your flags by learning from each release.
- Remote configuration – Update your app in real-time without a code deployment. Toggle flags on and off, and even make changes to your experiments while they are running.
- Low latency – In-memory bucketing means no blocking network requests. Test in performance-critical code paths, secure environments and more.
- Real-time results – Optimizely's Stats Engine provides best-in-class statistical modeling and immediate, trustable results without waiting for long, manual data queries.
- Cross-platform experimentation – Run server-side or client-side on any connected device—mobile apps, websites, TV apps—with consistent bucketing across different languages.
Learn more about major concepts in Optimizely Feature Experimentation or jump into creating your first experiment:
- Define feature flags that you will use to roll out feature code gradually, make remote configurations or run experiments. Choose user IDs, target audiences with attributes, track events and preview flag variations.
- Use your feature flag to run A/B tests without deploying code.
- Analyze the results of your experiment.
See the SDK reference guides for details about each API method, such as required arguments, return values and side effects.
See the Best Practices section for recommendations and considerations when implementing an Optimizely Feature Experimentation SDK.

To build a company-wide experimentation program, consider pairing Optimizely's server-side experimentation product, Optimizely Feature Experimentation, with our client-side experimentation product, Optimizely Web Experimentation. See our knowledge base article: Experiment end-to-end with Optimizely Web Experimentation and Optimizely Feature Experimentation.
If you have any questions, contact support or reach out to your Customer Success Manager. We are happy to help you set up any of our SDKs!
