Galene or Galène is a free and open-source multiplatform videoconferencing system that aims to use moderate server resources and to be very simple to install, administer and maintain.

[2][3] Galene was initially developed in the spring of 2020, during the first COVID-19 lockdown in order to provide a platform for remote teaching and remote examinations for the Department of Computer Science of the University of Paris-Cité.[4].

In September 2020, it started being used for staff meetings in addition to teaching, and was later used for remote access at a number of scientific and technical conferences.

Between September 2020 and February 2021, development of Galene was partly supported by Nexedi.

[9] Galene comes bundled with a default client that is written in JavaScript and is able to run in recent versions of all major browsers.
