One small, dumb kernel
It routes events, enforces capabilities, and runs the sandbox. No business logic, no opinions. Replacing what your agent can do never means forking the OS.
Unicity Astrid OS · by project
A modular operating system
for AI agents.
Every ability is a sealed capsule: the model, the memory, the tools, the guards. Snap them together into an agent, swap any part later, and it can never take more than you gave it. Unicity Astrid OS slots in underneath the agent you already use.
Let your AI actually do things, without handing over the keys.

Everything else is a capsule
The model, the loop, the memory, the tools, the skills, the frontends. Each one is sealed WebAssembly with its permissions declared up front. Swap any part, keep the machine.

Power that only narrows
Capabilities are signed tokens, not prompt instructions. A capsule can only hand its helpers less than it holds, never more. Every grant and denial lands on an audit chain you can read.
See it proven live →Assemble it like a loadout
Build your agent from parts. Swap any of them later.
Pick where it lives, start from an archetype, then mix and match capsules from the registry. Watch its manifest and its keys assemble as you go. The builder is a preview today; the capsules it is made of are real and on GitHub now.
