IMPORTANT - READ ME

Cosmos in its current stage is only usable for academic work. Some day Cosmos will be ready for production work, but to reach that stage we need more developers. Specifically, we need a few more low level developers to help the few core developers who are currently overwhelmed with work.

Download

Cosmos is available in two forms:
  • User Kit - User Kit allows you to develop your own custom operating system in Visual Studio. If you are new to Cosmos, start here.
  • Dev Kit - Dev Kit is the full Cosmos source with build tools. If you need to modify core Cosmos functions or modify built in drivers, boot, compiler, etc then you will need to use Dev Kit.
