Free
App Hub
Launch, install and update every Culltron app, with offline installers and version control.
Launch Candidate · v1.0.0-lc1
Culltron Core OS
An offline-first operating system that respects the machine and the person using it: light on old laptops, secure by default, quiet about the network, and yours to own. The desktop, the App Hub and every Max app are built to work without permission from the cloud.
System requirements
Designed to keep older hardware useful.
Modest minimums on purpose. If a machine can boot a modern 64-bit OS, it can likely run Culltron.
| Component | Minimum | Recommended |
|---|---|---|
| CPU | 64-bit (x86-64) | 64-bit dual-core or better |
| Memory | 2 GB RAM | 4 GB RAM |
| Storage | 20 GB free | 20 GB+ (SSD preferred) |
| Graphics | Any GPU with basic compositing | Hardware-accelerated GPU |
| Network | Not required to run | Optional — for updates & cloud features |
Note: actual performance depends on your specific hardware and the apps you run. These figures are honest targets for the launch candidate, not guarantees for every device.

Security defaults
Sensible from the first boot.
Culltron ships locked-down where it matters and transparent everywhere else. You can see what's on, and change what you need.
- Firewall on by default, managed through Sentinel.
- No mandatory account — set up and use the OS fully offline.
- No background telemetry collecting your activity.
- Hardening visibility — see the system's posture, not a black box.
- Opt-in network features are named, so nothing leaves quietly.
- First-run setup walks you through privacy, tier, apps and Aria mode.
We don't claim the OS is "100% secure" — no system is. We give you good defaults and clear visibility so you can stay in control.
Built in
Three pillars that make Culltron feel complete.
Bridge
Run many Windows applications through managed Wine profiles — install wizard, per-app shortcuts and isolated prefixes. Compatibility varies by program, but the common cases are easy.
Aria
An assistant with four modes you control. Keep it off, use offline rules, run a local model, or bring your own API keys. It never phones home in the background and always confirms before acting.
Sentinel
Defensive endpoint protection built into the OS: scanning, quarantine, firewall and hardening visibility — running offline, with no "100% secure" promises and clear, readable results.

docs/CORE_OS_BUILD_GUIDE.mdstep by step. - Boot, run first-run setup, and you're on Culltron.
Prebuilt ISO
A ready-to-flash ISO is coming at launch — download, write to a USB drive, and install like any modern OS. We'll publish it here when it's ready, with verification details.
- One download, write to USB, install.
- Published with checksums for verification.
- No always-online activation checks.
OS FAQ
Common questions.
Will it run on an old laptop?
That's the design goal. The OS targets a 64-bit CPU and 2 GB of RAM as a minimum (4 GB recommended) with about 20 GB of storage, so machines that struggle elsewhere stay productive.
Where's the ISO?
Today you build Core OS from source with the provision script, or follow docs/CORE_OS_BUILD_GUIDE.md. A prebuilt ISO arrives at launch. This is the launch candidate, v1.0.0-lc1.
Is my data collected?
No forced telemetry, no mandatory account. Anything that uses the network — updates, cloud sign-in, Aria API mode, Mail sync — is opt-in and named.
Can the AI work without internet?
Yes. Aria's Offline Rules mode needs no network, and Local Model mode runs on your own hardware. Only API mode reaches out, and only with your own keys, which stay on your device.
Can I run Windows apps?
Many of them, via Bridge and its managed Wine profiles. Compatibility depends on the specific program, but Bridge makes the common cases straightforward.
