Flatboard: Simple, Lightweight, Modern, Flat-File Forum, Using JSON and Markdown

I've been trying to look for a free alternative to MyBB (it seems stuck in development), with a discourse/flarum style out of the box, but without the need of a MySQL/Postgre installation.

This is the best I've come so far, although I was really looking for something for with SQLite, as it's enough for a small forum, but I came empty-handed with this requirement.

Flarum is cool, but It's too early, and I need something to upload into a sharing hosting without too much hassle. I'm looking for that compromise between control and hands-off.
