oh my god I just spend the last 6 months building something exactly like this as an internal tool because i couldn't find ANYTHING open-source that was remotely powerful enouhh for what i needed. this fits basically every single use case i had, i would only have to write a custom storage format to make data git-trackable.

i'm gonna go cry now.

please don't tell me this has been out for a while and i missed it.
