Where can I host my web application for free?

I have a web application that uses PHP and AngularJs. So I tried google appengine but somehow it just isn't cooperating with me. I've deployed projects (that dont use Angular) onto Heroku with success. However i find that Angular and heroku doesn't play well together for some reason. I coded my web application with Netbeans but when i try to deploying to AppEngine and Heroku, it just doesn't work out.

Does anybody know where I can host my web application for free?

I get that sometimes these things are tricky and I may have missed a step for deployment, any information is greatly appreciated.
