The Mission

LiveJournal.org is the "non-profit" wing of LiveJournal.com.
While LiveJournal.com, the site, relies on money from users to pay for the servers and bandwidth, the LiveJournal code remains free.

See Danga.com for descriptions of our infrastructure code, and code.sixapart.com for repo information.

The Source

The LiveJournal source is available through subversion.

Commits as they happen are posted on the LiveJournal changelog blog.

The Development

The developers hang around lj_dev, the LiveJournal development community. Client authors should look at lj_clients.

Much of the documented developer information, including the database scheme and the client protocol, is available at LiveJournal.com's developer area.
