## What it is
Config Syncer (formerly Kubed) is a Kubernetes operator by AppsCode that keeps ConfigMaps and Secrets synchronized across namespaces and clusters. It runs as a controller in a Kubernetes cluster and propagates configuration changes automatically.

## Use cases
- sync configmaps across kubernetes namespaces
- keep secrets consistent between clusters
- propagate tls certificates to all namespaces
- share configuration across microservices in kubernetes
- automatically update secrets when they change
- replicate kubernetes configuration to multiple clusters

## When to choose
- you run multiple namespaces or clusters that need identical ConfigMaps or Secrets
- you want automatic propagation of certificate or credential updates in Kubernetes
- you prefer a Kubernetes-native operator with declarative sync configuration

## When to avoid
- you need general GitOps configuration management rather than ConfigMap/Secret sync
- you are not running Kubernetes
- you need syncing of arbitrary resources beyond ConfigMaps and Secrets
