That said; for hobby stuff I've switched to a cheap VPS plus Dokku [0] and haven't looked back. Works with Heroku buildpacks and even runs custom Dockerfiles if you need anything fancy. Hardly requires any maintenance.
There's a couple of alternatives like Deis [1] and Flynn [2] that offer more advanced features, but they're much more complex and way overkill for my pet projects.
