Optimizely Full Stack 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 roll out or roll back features immediately. All of this functionality is available with minimal performance impact via easy-to-use, open source SDKs.

Optimizely feature flagging is the free plan for Full Stack, designed for startups and teams looking to get started. It comes with free feature flags and feature rollouts and the ability to run one feature test at a time.

See the following architectural diagram for an overview of Full Stack's server-side SDKs:
And our client-side SDKs, highlighting our mobile SDKS:

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 features by learning from each release.
- Remote configuration: Update your app in real time without a code deploy. Toggle features on and off, and even make changes to your experiments while they're 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 Full Stack or jump into creating your first experiment:
- Install the SDK (optional: customize i.e. configuration polling interval) and instantiate it in your code.
- Define feature flags that you'll use to roll out features, make remote configurations, or run feature tests.
- Use your feature flag to run feature tests without deploying code, or run a standalone A/B test. Choose user IDs, target audiences with attributes, track events, and preview experiment variations.
- 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 a Full Stack SDK.

To build a company-wide experimentation program, consider pairing Optimizely's server-side experimentation product, Full Stack, with our client-side experimentation product, Optimizely Web. See our support help center article: Experiment end-to-end with Optimizely Web and Full Stack.
If you have any questions, please contact support. We are happy to help you set up any of our SDKs!
