Are there any other API gateways with middleware support other than vulcand?

I've been looking for an API gateway solution (or just a proxy) in #golang that offers middleware support like Vulcand does ( http://vulcand.github.io/ ), are there any other options there?

Vulcand doesn't very much alive right now.

Kong does all of this very nicely.  getkong.org

caddy has plugin support, but without knowing your specific scenario, I'd say it's the most flexible option.

The ideal solution would be something that allows me to easily route requests based on host/path to specific servers on the backend, allows for easy embedding and offers a middleware stack that I can hook into. Kind of like Netflix's Zuul ( https://github.com/Netflix/zuul ) but in go :D

Caddy is probably what you want. Traefik looks interesting but I haven't tried it yet.
