The Future of
Microkernel OS
TreamOS is a community-built microkernel operating system designed for security, modularity, and performance. Join thousands of contributors shaping the next generation of operating systems.
A Microkernel OS Built by the Community
TreamOS takes a modular approach to operating system design. By keeping the kernel small and delegating services to user space, we achieve unprecedented security and reliability.
Security First
Isolation of services in user space limits the attack surface. A fault in one component cannot bring down the entire system.
Modular Design
Every OS service is a separate module. Add, remove, or update drivers and servers without rebooting or touching the core kernel.
High Performance
Optimised inter-process communication and a minimal kernel footprint translate to fast boot times and low overhead at runtime.
Open Source
Every line of TreamOS is open source. Read it, audit it, fork it. The community decides the direction of the project together.
How the Microkernel Works
Unlike monolithic kernels, TreamOS keeps only the essentials in privileged mode. Everything else runs safely in user space.
Built by People Like You
TreamOS is shaped by a global community of OS enthusiasts, researchers, and developers. No matter your skill level, there is a place for you here.
