Install: brew install fabio

About:
Fabio is a zero-conf load balancing HTTP(S) router designed to natively support Consul. It automatically discovers services and routes traffic based on tags, eliminating the need for manual configuration. This provides a simple, high-performance way to expose services to the outside world without a separate reverse proxy.

Key Features:

Zero-configuration service discovery via Consul
Native TLS termination and routing
High-performance HTTP/HTTPS routing with low latency
Automatic SSL certificate management with Let's Encrypt

Use Cases:

Automatically routing traffic to microservices registered in Consul
Simplifying TLS termination for internal services
Load balancing containerized applications in a dynamic environment

Alternatives:

traefik – Traefik offers broader provider support (Kubernetes, Docker) but is more complex; Fabio is lightweight and Consul-focused.
nginx – Nginx requires manual configuration updates, whereas Fabio updates routes automatically based on service health.
