Rift vs AgentFS

AgentFS keeps one agent's files in a single database file. Rift keeps files in sync across machines and owners.

What AgentFS is

AgentFS is an open-source filesystem for agents from Turso. An agent's files, its key-value state and a log of every tool call live in one SQLite file, so a whole session can be copied, queried or thrown away. An agent can work on a copy of a project while the original stays untouched. It is in beta.

How they differ

AgentFS holds one agent's state in one database file, and it shares that state as a whole database. Rift moves files between machines and between owners, one folder at a time.

Which to choose

Choose AgentFS when

  • An agent should change files freely while the originals stay untouched.
  • You want a record of every tool call next to the files.
  • Everything runs on one machine.

Choose Rift when

  • Files should move between machines one folder at a time.
  • Another person or agent needs some of the files.
