Co-Founder of Platform.sh here: I am not extremely familiar with runnable.com so I won't comment on them. Anyway, this is true we currently focus on the PHP market. Though you can already deploy nodejs applications (or a mix as we support complex multi-app clusters). The platform itself is totally abstract so we will probably add in the near future many other run-times. The main difference I think it would be interesting to point out is that Platform.sh is a production system... not a staging thing. What we clone into staging is production .. with all the data.. however complex it is. And we do it really fast. And we run production in a multi-datacenter / scalable / highly-available setup. BTW we are hiring like crazy so if you want to work on your pet language having our features... contact me :) We are a fully distributed company... so u can be anywhere the world.
