What is AtomJump.org?
A credible alternative to the Facebook & WhatsApp combination, AtomJump.org is open software designed for self-publishing and communicating instantly with your own group of people, while keeping it fully under your own control. The companion AtomJump.com site is a hosted version of the AtomJump.org software, for an easy set-up, or for high traffic installations.
AtomJump.org provides a flexible and expandable plugin system, which anyone can write in PHP or NodeJS. The system runs on a low-end LAMP server, and end users can log in and chat from any browser.
