Fabio vs Redbird

Fabio is a self-hosted HTTP and TCP reverse proxy that builds its routing from Consul service data. Services can announce accepted paths with tags such as `urlprefix-/user`; Fabio then refreshes its routing table when Consul changes, without restarting or reloading. Its main role is distributing incoming HTTP(S) and TCP traffic from the internet to frontend services. It is not intended for frontend-to-backend or backend-to-backend routing, where Consul service discovery is used instead. Fabio provides route-specific access control, authorization, customizable logs, redirects, compression, header injection, path changes, WebSockets, server-sent events, and transparent gRPC proxying. It supports TLS termination, dynamic certificate stores, HTTPS upstreams, raw TCP, TCP-SNI forwarding, and traffic shaping by percentage. A web UI shows the active routes, with metrics integrations. Fabio is free, open-source software for Linux, macOS, and Windows, and requires Consul for service discovery.
