PhyAgentOS-core vs PhyAgentOS

The two are close in size: 2.1k stars for PhyAgentOS-core, 2.1k for PhyAgentOS. Over the days we have tracked them PhyAgentOS-core moved +18.8% and PhyAgentOS +30.4%, so PhyAgentOS is growing faster right now.

Neither one leads on the six capability axes, so the choice comes down to which of them fits the way you already work.

Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.

Where they stand today

Decouples cognition from physical hardware with a session-centered runtime and small target adapters so the same agent codebase runs across sim and real robots.

Six axes, head to head

Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.

Which one to pick

Pick PhyAgentOS-core if…

Safety-first — built-in multi-layer validation (critic → preflight → target-side SafetyGuard) and auditable file protocols make it suitable for real-robot deployment.

Runs in cli. Works with other-fixed.

Pick PhyAgentOS if…

Hardware-agnostic — pick PhyAgentOS when you need a self-hostable, auditable runtime that runs identical sessions across sim and real targets with strict multi-layer safety.

Runs in cli. Works with other-fixed.
