GNU social 1.1.3

February 2015-02-27

(c) Free Software Foundation, Inc (c) StatusNet, 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.

Some other files to review:

  • INSTALL: instructions on how to install the software.
  • UPGRADE: upgrading from earlier versions
  • CONFIGURE: configuration options in gruesome detail.
  • PLUGINS.txt: how to install and configure plugins.
  • EVENTS.txt: events supported by the plugin system
  • COPYING: full text of the software license

Information on using GNU social can be found in the "doc" subdirectory or in the "help" section on-line, or you can catch us on IRC in #social on the freenode network.


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 sites like Twitter, Google+ or Facebook, 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 an open standard called 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.

It is shared with you in hope that you too make an service available to your users. To learn more, please see the Open Software Service Definition 1.1:

New this version

This is a security fix and bug fix release since 1.1.3-beta2. All 1.1.x sites should upgrade to this version.

So far it includes the following changes:

Upgrades from StatusNet 1.1.1 will also experience these improvements:

  • Fixes for SQL injection errors in profile lists.
  • Improved ActivityStreams JSON representation of activities and objects.
  • Upgrade to the Twitter 1.1 API.
  • More robust handling of errors in distribution.
  • Fix error in OStatus subscription for remote groups.
  • Fix error in XMPP distribution.
  • Tracking of conversation URI metadata (more coherent convos)


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:

  • 1.1.x "stable", few updates, well tested code
  • master "testing", more updates, usually working well
  • nightly "unstable", most updates, not always working

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

Further information

There are several ways to get more information about GNU social.
