As @debergalis mentioned above, we are working with a select group of package authors to migrate their demo/doc sites from Meteor.com free hosting to Galaxy, free of charge. See the details here.
Also, we’ve formalized the ability to request access to Galaxy Community Sandboxes, a free version of Galaxy that lasts for 7-days, no credit card required. While we’ve supported community events (e.g. hackathons, workshops, and Meetups) with generous Galaxy credits in the past, Galaxy Community Sandboxes will make it even easier for event organizers to provide a great deployment option for Meteor apps. We can’t wait to see how the community will put these to use in future events!
