Very, very excited this is going live today. We're looking forward to the awesome things developers can do with this. We've already been extremely surprised by the creativity of our end-users and are expecting a similar story from our developers.

A few quick ideas:

1. hook your own SaaS app up to Zapier so all of our users (and your customers!) can use it

2. write an integration for a SaaS app you don't own but want to integrate with

3. connect your in-house tools to external SaaS apps through Zapier
