GNU social 1.20.x

(c) 2010-2019 Free Software Foundation, Inc

This is the README file for GNU social, the free software social networking platform. It includes general information about the software and the project.

The file has useful instructions on how to install this software.

System administrators may find the DOCUMENTATION/SYSTEM_ADMINISTRATORS directory useful, namely:

  • upgrade_from: upgrading from different software
  • configuration options in gruesome detail.
  • how to install and configure plugins.

Developers may find the DOCUMENTATION/DEVELOPERS directory useful.


GNU social is a free social networking platform. It helps people in a community, company or group to exchange short status updates, do polls, announce events, or other social activities (and you can add more!). Users can choose which people to "follow" and receive only their friends' or colleagues' status messages. It provides a similar service to proprietary social network sites, but is much more awesome.

With a little work, status messages can be sent to mobile phones, instant messenger programs (using XMPP), and specially-designed desktop clients that support the Twitter API.

GNU social supports open standards (such as OStatus that lets users in different networks follow each other. It enables a distributed social network spread all across the Web.

GNU social was originally developed as "StatusNet" by StatusNet, Inc. with Evan Prodromou as lead developer.

The primary output for GNU social is syslog, unless you configured a separate logfile. This is probably the first place to look if you're getting weird behaviour from GNU social.

If you're tracking the unstable version of GNU social in the git repository (see below), and you get a compilation error ("unexpected T_STRING") in the browser, check to see that you don't have any conflicts in your code.

Unstable version

If you're adventurous or impatient, you may want to install the development version of GNU social. To get it, use the git version control tool like so:

git clone

In the current phase of development it is probably recommended to use git as a means to stay up to date with the source code. You can choose between these branches:

  • 1.20.x "oldstable", few updates, well tested coded
  • master "stable", usually working well
  • nightly "testing", most updates, not always working as expected

To keep it up-to-date, use git pull. Watch for conflicts!

As in any upgrade, do not forget to run /scripts/upgrade.php.
