A system is provided comprising a computer and application that creates a development zone in response to a first message. The zone comprises a recording of state-based references to files and folders of a master production build in read-only and read-write copies of the build. The system receives another message containing a request to commit changes to the build. The changes comprise updating the build with changes to the read-write clone. The system compares the read-only snapshot with the current build to determine changes committed after the zone creation. The system compares changes to the read-write clone and changes committed to the build after zone creation. The system identifies files and folders changed in the read-write clone and commits the changes made to the read-write clone to a staging build and the master production build.
