Dropbox finally open-sources its Hackpad collaborative document editor

Dropbox has released the source code for its Hackpad collaborative note-taking application under an open-source license.

Dropbox acquired Hackpad in April 2014. About a year later the team behind Hackpad informed users that the code would become available under an open-source license “in the next few weeks.” When that didn’t happen right away, some people got frustrated and took to GitHub to vent.
