Show HN: Try out OSS webapps before installing them

We built this as a little hackathon project on top of our "get a dozen staging servers" platform at https://layerci.com

The "show layer" gallery lets you create instantaneous staging servers to play around with software, as well as discussing it and submitting your own favorites for the community to use.

Submitting is currently pretty difficult, but we'll try to add any projects you submit, even if you don't have a screenshot or staging configuration for it.
