[Flipt](https://www.flipt.io) 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](https://www.flipt.io/docs/guides/get-going-with-gitops), you can easily integrate Flipt into your CI/CD workflows to enable continuous configuration and deployment with confidence.

## Use cases

Flipt supports use cases such as:

- Enabling [trunk-based development](https://trunkbaseddevelopment.com/) workflows

- Testing new features internally during development before releasing them fully in production

- Ensuring overall system safety by guarding new releases with an emergency kill switch

- Gating certain features for different permission levels allows you to control who sees what

- Enabling continuous configuration by changing values during runtime without additional deployments




## Values

- 🔒 **Security** - HTTPS, OIDC, JWT, OAuth, K8s Service Token, and API Token authentication methods supported out of the box.

- 🎛️ **Control** - No data leaves your servers and you don't have to open your systems to the outside world to communicate with Flipt. It all runs within your existing infrastructure.

- 🚀 **Speed** - Since Flipt is co-located with your existing services, you do not have to communicate across the internet which can add excessive latency and slow down your applications.

- ✅ **Simplicity** - Flipt is a single binary with no external dependencies by default.

- 👍 **Compatibility** - GRPC, REST, MySQL, Postgres, CockroachDB, SQLite, LibSQL, Redis, ClickHouse, Prometheus, OpenTelemetry, and more.




## Features

- Stand-alone, single binary that's easy to run and [configure](https://www.flipt.io/docs/configuration/overview)

- Ability to create advanced distribution rules to target segments of users

- Modern UI and debug console with dark mode 🌙

- Import and export to allow storing your data as code

- Works with [Prometheus](https://prometheus.io/) and [OpenTelemetry](https://opentelemetry.io/) out of the box 🔋

- CloudNative [Filesystem, Object, Git, and OCI declarative storage backends](https://www.flipt.io/docs/configuration/storage#declarative) to support GitOps workflows and more.

- Audit logging with Webhook support to track changes to your data

### Sandbox

[Try Flipt](https://try.flipt.io) in a deployed environment!

**Note:** The database gets cleared **every 30 minutes** in this sandbox environment!

### Homebrew :beer:

```bash

brew install flipt-io/brew/flipt

brew services start flipt

# or run in the foreground

flipt

```

## Integration

Check out our [integration documentation](https://flipt.io/docs/integration/) for more info on how to integrate Flipt into your existing applications.

There are two ways to evaluate feature flags with Flipt:

- [Server Side](#server-side-evaluation)

- [Client Side](#client-side-evaluation)

### Server Side Evaluation

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:

- [GRPC](#grpc)

- [REST](#rest)

#### GRPC

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](https://www.flipt.io/docs/integration/server/grpc) for the latest information.

#### REST

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](https://www.flipt.io/docs/reference/overview) can also be used with any language that can make HTTP requests.

See our [REST Server SDK documentation](https://www.flipt.io/docs/integration/server/rest) for the latest information.

### Client Side Evaluation

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](https://www.flipt.io/docs/integration/client) for the latest information.




## Release Cadence

Flipt follows [semantic versioning](https://semver.org/) 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

[Development](DEVELOPMENT.md) 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!

## Licensing

There are currently two types of licenses in place for Flipt:

1. Client License

2. Server License

### Client License

All of the code required to generate GRPC clients in other languages as well as the [Go SDK](/sdk/go) are licensed under the [MIT License](https://spdx.org/licenses/MIT.html).

This code exists in the [rpc/](rpc/) directory.

The client code is the code that you would integrate into your applications, which is why a more permissive license is used.

### Server License

The server code is licensed under the [GPL 3.0 License](https://spdx.org/licenses/GPL-3.0.html).

See [LICENSE](LICENSE).
