Yes you right, both are good enough and everyone want to simplify his backend schemas...

I want to note big difference between haproxy and nginx, first of all "nginx is webserver" (nginx HTTP server) and then proxy/loadbalancer(may be used) whereas haproxy is pure loadbalancer. Enterprise bare metal and hardware appliances for proxy/loadbalance built on top of haproxy

nginx is wide spread because of usage as good minimalistic web server

nginx lacks of many good improvements and fixes which does not accepted upstream devs, so nginx has so many 3rd party modules which most of them are invalid because of nginx version changes or requires old buggy nginx version to run

openresty well it is standalone product, it is build on top nginx with many 3rd party modules and many improvements accepted/not accepted by upstream, and of course big Lua support

haproxy is good enough with it's: - full stats rather os nginx stab_status (full stats only in nginx plus) - much load balancing mechanism support than os nginx (full support needs nginx plus, e.g: for sticky sessions)

for me, in the first place haproxy and then nginx

I good welcome opensourcing parts of nginx, take that way
