Turris OS is based on the Linux distribution OpenWRT, which is developed primarily for routers. The Turris project adds additional software to this operating system to extend its default functionality.

This article describes what software is in Turris OS beyond OpenWRT. This is not a complete list of added packages, but a list of larger projects that Turris OS adds to OpenWRT. You will find a description of the added software, what function the software has in Turris routers, links, source codes and history of releases, including a list of changes.

This section describes software, which is developed directly by Turris developers and is not part of OpenWRT.

Foris is a web interface developed specifically for Turris routers. Its purpose is to offer a simple router setting without the advanced knowledge of OpenWRT and Turris OS.

• If you find any error in Foris, please let us know at GitLab.
• Additionally, Foris features can create users themselves. For this purpose, we have prepared the Turris plugin for tutorial.

One of the objectives of the Turris project is to increase the security of the routers by using them regular firmware updates. Updates are automated by Updater, since Turris OS 3.7, Updater has been upgraded to a new generation - Updater-ng.

Turris routers use the BTRFS file system to record the status of all files at a given time (so-called snapshots). This lets you take all files to the state they were at when the snapshot was created. This enables the user to simply return to a functional configuration or to temporarily return to an earlier version of the system. Schnapps is a tool, which simplifies this process.

In this section, we describe software that is not developed exclusively by Turris developers, and its use exceeds the scope of the project. Yet for different reasons, it is still a significant part of the functionality of Turris routers.

This software even though it can still be found in the router is already considered obsolete and either gradually replaced or withdrawn without compensation. This group of software is no longer being actively developed and reported errors are given much lower attention. Possible that bugs may never be fixed.

Majordomo is a tool for visualising router traffic. It is currently being replaced by PaKon.
