kutu OS is a Linux desktop that treats memory as the scarce resource it now is. Between 2025 and 2026 DRAM prices roughly quintupled; kutu applies the memory-conservation stack Google and Meta proved at fleet scale — zstd-compressed zswap, MGLRU page aging, DAMON proactive reclaim and PSI-driven systemd-oomd — to an ordinary Arch-based XFCE desktop, with safe defaults, per-application memory ceilings, and nothing to configure.
| Repository | What it is |
|---|---|
| kutuso/os | The distro — archiso profile, packages, offline Calamares installer, QEMU-gated CI, documentation |
| kutuso/doctor | kutu-doctor — live memory-health dashboard, stack verifier and mode switcher (Python; runs on any distro) |
| kutuso/libmempressure | libmempressure — memory-pressure events from kernel PSI for C, C++, JVM and Python; an onTrimMemory() for Linux (RPM + DEB packaging included) |
the live desktop and the offline installer — real screenshots, captured from the same ISO CI smoke-tests on every release
