Hoodie provides a backend for you, you manage the browser.

Meteor (and Derby etc) is a full stack JS setup, where you manage both the browser and node.

Both do data sync.

In addition: Meteor data is public by default, and the architecture is always online, whereas Hoodie data is private by default, and the architecture is offline by default.

Besides the points already mentioned, Meteor is VC backed. Hoodie is an open source project first, that we founded & bootstrapped a company for to sustain its future, and that we will eventually turn into a non-profit. We are and will be not accountable to any investor with questionable interests in an open source project.
