A self-hosted, open-source feature flag management tool. Pioneer is intended to assist small to medium-sized organizations in a transition from a monolith to microservices architecture. Users can easily roll out individual microservices to a specified subset of users without the need for extensive configuration or additional infrastructure. Pioneer's architecture consists of a NATS JetStream server, a React-based dashboard, and a Node.js daemon. SDKs in Ruby, Node, and Golang are available. Check out our webpage for more details.
