Fork documentation
Software you can shape,
in a space you control.
What is Fork?
Fork is an application platform built around spaces: isolated sandboxes that can host a full web application and its supporting tools. The Fork Agent lives beside the application and can inspect, change, run, and verify it. The control plane keeps accounts, policy, billing, and managed services outside the application runtime.

OrganizationsThe boundary for ownership, members, services, and billing.
Users & rolesAccounts, membership, built-in roles, and custom permissions.
CreditsA shared wallet for agent and managed-service usage.
Fork AgentA coding agent that works inside the selected space.
DatabasePersistent documents with trusted automatic scoping.
ConnectorsUser-scoped external app connections through Composio.
SecretsEncrypted custody and memory-backed runtime delivery.
