Do I need Durables to use Nanite, or the other way round?+-
Nanite stands on its own: create sandboxes over its API and run anything in them. A durable is an agent we run for you on a Nanite sandbox, so it uses the same credits and shows up among your sandboxes.
Which models can my agents use?+-
Any your code calls from a sandbox. Durables run Claude, GPT and any model on OpenRouter with your own key, kept as a secret outside the machine. We do not charge for tokens.
Where does it run?+-
On bare metal in Sydney, Australia, for now. Model calls go from the sandbox straight to your provider.
What happens when my credits run out?+-
Running sandboxes stop and their disks are kept, and nothing wakes them until you top up. Then they start again on the next request.
Is it open source?+-
The runtime is: shuru is Apache 2.0 on GitHub. Nanite and Durables are the hosted services built on it.
