Comfortable from the start
A traditional applications menu, panel, windows, files and settings keep the desktop understandable for people coming from Windows or other conventional computers.
Explore the desktop
Your computer. Your rules.
A familiar desktop that puts you back in control.
Sentinel Linux is a Debian-based desktop for everyday computing. It keeps ordinary work local, makes important system choices visible, and gives you a familiar environment without forced cloud accounts or hidden remote control.
Your computer comes first
Core work is designed to happen on your own system. Online services can be used where useful, but ordinary access to your files and tools should not depend on someone else’s cloud service.
Read the local-first missionImportant changes stay visible
Security choices, desktop behaviour and system policy are delivered through versioned Debian packages so they can be inspected, updated, repaired and audited.
Understand Policy as Packages
Everyday computing
A useful desktop, not just a technical project.
Sentinel Linux brings together a browser, notes, documents, calendar, contacts, password storage, bookkeeping, maintenance, inventory, pantry, media tools and other local applications in one consistent desktop suite.

Optional assistance
AEGIS helps without taking ownership away.
AEGIS is Sentinel Linux’s optional local-first assistant layer. It is intended to explain, organise and guide authorised tasks while respecting explicit boundaries and keeping the user as the final authority.
Assistance should increase understanding and control, not replace them.
Manuals for everyday tools and system commands.
