Acre is an open development environment for developing web apps using Javascript

Acre is the backend for the Freebase Apps platform, which provides hosted, social app development using server-side Javascript.

This open source release allows you to run Acre on your own server.

Features:

• server side coding in Javascript
• cross-app require() gives you the ability to safely share code
• particularly suited to apps that use Freebase data (fast freebase API queries on the back-end)
• very fast ramp-up time
