Fabio is an HTTP, HTTPS, TCP, and gRPC reverse proxy and load balancer that configures itself dynamically from service data stored in Consul. Services announce their routes via Consul tags (e.g. urlprefix-/user), and fabio updates its routing table instantly without restarts or config reloads.

Use cases

• load balance microservices with consul service discovery
• reverse proxy that updates routes without reload
• route http traffic by path prefix from consul tags
• tcp proxy for database ports behind consul
• grpc proxy with tls termination
• zero-downtime routing table updates for services

When to choose

• you already use Consul for service discovery and want automatic routing
• you need hot-reloading routes without downtime or config file templating
• you need a mix of HTTP, TCP, and gRPC proxying in one tool
• you want built-in metrics backends like Prometheus, DataDog, or Graphite

When to avoid

• you don't use Consul and have no service registry
• you need a general-purpose edge proxy with rich plugin ecosystems like Envoy or NGINX
• you need layer 7 features beyond path/host routing such as complex traffic policies
• you want a Kubernetes-native ingress controller
