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.
