Is there something that makes this specific to Chrome or is this a web compatible library?
OP- the term "chrome native" is pretty inaccurate and is giving people the wrong idea about what you're showing off.
It uses, relies and depends on Chrome exposed primitive such IndexedDB. Hence the term chrome native.
Honestly, didn't give much thought to it. Just rolled with it :D
Whilst there's often good reasons to state that something will only work on Chrome - it's something that should probably be wrapped in a something approximating a mild apology:
"Whilst this might work on any browser that supports IndexedDB I've currently only tested it on blah blah" - that kind of thing...
