Nine Worlds.One System.
Yggdrasil OS is an operating system in development. Privacy and security are its foundation.
The trailer shows Yggdrasil OS booting up. It gives an impression of the vision. It is not a demo of today's state.
Privacy by Default
Yggdrasil is a flexible operating system with binding protection rules for applications, data and connected systems. Privacy and security form the foundation, from the personal device to servers, networks and industrial use.
Yggdrasil OS starts from one question: what would an operating system look like if you rethought it from scratch today, with AI?
Your data. Your control.
Protection rules bind applications and data. They are not a setting you have to hunt for.
A system the way you need it.
You describe what you need in conversation. The matching working environment follows from that.
Across device boundaries.
Storage, shared resources and AI-organised backups reach beyond your own devices. If you like, you share resources with others.
Developed together.
Yggdrasil is meant to grow as a community: with wishes, experience, test devices and expertise.
These are goals of the vision. The development status shows what has been built so far.
Nine worlds, nine parts of the system
Each world stands for one part of the system. A world only lights up once that part is built, tested and approved by Gerald. The light follows the evidence, not the schedule.
- Glowing: built, tested and approved.
- Glimmering: built, testing and approval still open.
- Dark: not started.
- Helheim glimmeringRescue when everything else fails, without AI and without a network.
- Niflheim glowingThe system can be halted and locked.
- Svartalfheim glimmeringYour data and the way back to an earlier state.
- Asgard glimmeringApprovals and rules about who may do what.
- Vanaheim glimmeringNew versions get activated, with a safe way back.
- Midgard glimmeringYour applications and data.
- Alfheim glowingThe interface you see.
- Jötunheim glimmeringThe border to the outside world.
- Muspelheim darkDevelopment with AI. Comes in a later stage.
