Unleash is the open-source feature management platform. It provides a great overview over all feature toggles/flags across all your applications and services. Unleash enables software teams all over the world to take full control on how they enabled new functionality to end users.
- Extremely scalable with evaluations on the client side. Used in enterprises handling more than 10k req/s. [Read more about our architecture](https://docs.getunleash.io/)
In addition there exists a good list of [community developed SDKs](https://docs.getunleash.io/sdks/community), so there might already exist an implementation for your favorite programming language (e.g. [Rust](https://github.com/cognitedata/unleash-client-rust), [Elixir](https://gitlab.com/afontaine/unleash_ex), [Dart](https://pub.dev/packages/unleash), [Clojure](https://github.com/AppsFlyer/unleash-client-clojure), [NestJS](https://github.com/pmb0/nestjs-unleash), [Kotlin](https://github.com/silvercar/unleash-client-kotlin), [PHP](https://gitlab.com/minds/unleash-client-php) and more.)
The main motivation for doing feature toggling is to decouple the process for deploying code to production and releasing new features. This helps reducing risk, and allow us to easily manage which features to enable
This repo contains the unleash-server, which contains the Unleash Admin UI and the Unleash API. In order to make use of unleash you will also need a client SDK.
It's fine to have a system for turning stuff on and off. But some times we want more granular control, we want to decide who to the toggle should be enabled for. This is where activation strategies comes in to the picture. Activation strategies take arbitrary config and allows us to enable a toggle in various ways.
The [client SDKs](https://docs.getunleash.io/sdks) provides a simple abstraction making it easy to check feature toggles in your application. The code snippet below shows how you would use `Unleash` in Java.
Unleash is open source and you are free to run your own instance. The [Getting started guide](https://docs.getunleash.io/docs/deploy/getting_started) goes through all the options on how to run Unleash.
After numerous request we have created a separate company, Unleash-hosted, which offer Unleash as a Service. Unleash-hosted allows you to focus on you core business and have someone else taking care of hosting and maintaining Unleash.
Go to [getunleash.io](https://www.getunleash.io/plans) to learn more about this offering and start using Unleash today. This service also includes official support.
