I have had an amazing experience with ep.io. The invite list is a mile long, but if you have something that you already know you want to build, you can e-mail the team and they'll let you jump the queue (I think it's more they simply haven't sat down and powered through their list yet than any lack of capacity on their part). The team is very friendly, and they have an incredibly generous free quota as compared to other services (2 GB of files/database, 5 GB/month of bandwidth, and 16 MB of Redis - per app). They use plain old WSGI for the server, Postgres for the database, and they'll install any packages you put in a requirements.txt file, so no lockin. Haven't used Django with it, but so far my experiences with Flask are great.
