It would probably be harder to bend Django to use SQLite as a backend then it would be to just setup MySQL or PostGRES and use the existing Django tooling for it.
Ignore this, I was wrong. Django supports sqlite just fine. Last time I did anything with django I was an intern and just copied the setup from the readme which happened to include a mysql setup. I have not touched django since.
I'm not convinced this is true. Django supports SQLite out of the box, and otherwise database management is an exercise for the reader. The migration tools, for example, work fine with SQLite.
Agreed perhaps, but I still don't want to devops Postgres and I'd rather having tiny hosting costs for tiny apps. So I think there's a definite need here for this tooling.
