An enterprise-ready, GitOps enabled, CloudNative, feature management solution
Flipt enables you to follow DevOps best practices and separate releases from deployments. Built with high-performance engineering organizations in mind.
Flipt can be deployed within your existing infrastructure so that you don't have to worry about your information being sent to a third party or the latency required to communicate across the internet.
With our GitOps-friendly functionality, you can easily integrate Flipt into your CI/CD workflows to enable continuous configuration and deployment with confidence.

Check out our integration documentation for more info on how to integrate Flipt into your existing applications.
There are two ways to evaluate feature flags with Flipt:
Server-side evaluation is the most common way to evaluate feature flags. This is where your application makes a request to Flipt to evaluate a feature flag and Flipt responds with the result of the evaluation.
Flipt exposes two different APIs for performing server-side evaluation:
Flipt is equipped with a fully functional GRPC API. GRPC is a high-performance, low-latency, binary protocol that is used by many large-scale companies such as Google, Netflix, and more.
See our GRPC Server SDK documentation for the latest information.
Flipt is equipped with a fully functional REST API. The Flipt UI is completely backed by this same API. This means that anything that can be done in the Flipt UI can also be done via the REST API.
The Flipt REST API can also be used with any language that can make HTTP requests.
See our REST Server SDK documentation for the latest information.
Client-side evaluation is a great way to reduce the number of requests that your application needs to make to Flipt. This is done by retrieving all of the feature flags that your application needs to evaluate and then evaluating them locally.
See our Client SDK documentation for the latest information.
Flipt follows semantic versioning for versioning.
We aim to release a new minor version of Flipt every 2-3 weeks. This allows us to quickly iterate on new features. Bug fixes and security patches (patch versions) will be released as needed.
Development documentation is available for those interested in contributing to Flipt.
We welcome contributions of any kind, including but not limited to bug fixes, feature requests, documentation improvements, and more. Just open an issue or pull request and we'll be happy to help out!
Check out the examples to see how Flipt works in different use cases.
There are currently two types of licenses in place for Flipt:
- Client License
- Server License
All of the code required to generate GRPC clients in other languages as well as the Go SDK are licensed under the MIT License.
This code exists in the rpc/ directory.
The client code is the code that you would integrate into your applications, which is why a more permissive license is used.
The server code is licensed under the GPL 3.0 License.
See LICENSE.
