Nice move open-sourcing it. At the company I work for, we considered InboxSDK when making an Gmail-integrating extension.

But at the time it was closed-source so we went with the open-source Gmail.js[1] instead.

Now that InboxSDK is open-source too, how do you guys feel they compare? Do they have their different strengths or niches?
