Key Features

• SpritesHardware-isolated Linux computers for agents that sleep when the agent stops and wake up with the filesystem, running services, and installed dependencies right where they were.
• Sprite Block DeviceA durable, object-storage-backed filesystem that lets Sprites sleep without dying and roll back to any checkpoint in seconds.
• Automatic checkpointingThe Sprite checkpoints itself automatically so there's always a recent checkpoint waiting.
• No disk sizingDisk grows as you write, up to 100 GB per Sprite, and you're billed only for the bytes you actually store.
• ConnectorsConnect a service once for your whole org so every Sprite can reach it without pasting a token, with the credential held by an API gateway.
• Granular permissionsGrant access by Sprite name, by label, or down to a single endpoint.
• Auto key rotationRotate a credential once and every Sprite gets the update; cut off one Sprite without affecting the rest.
• Fly MachinesHardware-isolated VMs that boot in under a second, run close to users, and scale out to tens of thousands.
• HTTPS URL per SpriteEvery Sprite has an HTTPS URL so an agent-built app stays where it was created and goes live.
