Mattermost – chat and collaboration

What is Mattermost?

  • Mattermost is a fully featured chat service which can be used on most platforms.
  • The service runs locally at the UiO and can be used if you do not want to use cloud based services.
  • The interaction takes place in public channels, private channels and in instant messaging.
  • Everything is archived and searchable, and is available from desktop, laptop and smartphone.
  • Mattermost is available in a web browser, but can also be downloaded from Mattermost's website. The application is available on Mac, Windows, Linux, iOS and Android.
  • In the fall of 2019 Mattermost was opened for use also in teaching. Users who are not IT staff can order channel creation and self-register user groups.
