## What it is
Jupiter is a governance-oriented microservice framework for Go, developed and used in production at Douyu. It bundles web/gRPC servers, configuration, metrics, tracing, and service governance tooling with a companion console (Juno) and CLI toolkit.

## Use cases
- build microservices in go
- golang microservice framework with governance
- grpc service framework with metrics and tracing
- manage microservice configuration and governance
- production go framework for backend services
- service governance with etcd and a console

## When to choose
- you are building Go microservices and want batteries-included governance, metrics, and tracing
- your team wants an opinionated framework with a companion management console (Juno)
- you need gRPC and HTTP services with etcd-based configuration and service discovery

## When to avoid
- you want a minimal router or unopinionated library rather than a full framework
- your stack is not Go
- you prefer assembling your own stack from small libraries

## Facets
- artifact type: framework
- maturity: active
