Rift vs Archil

Archil is a fast shared disk for AI workloads. Rift shares single folders, encrypted so that whoever stores them cannot read them.

What Archil is

Archil is a serverless filesystem for AI. A server mounts an Archil disk and uses it like a local drive. It is built for data that many servers and agents share. A disk can sync to your own S3 bucket, or it can have branches and checkpoints.

How they differ

Archil shares by the disk. A server that is allowed to mount a disk can read all of it, and Archil manages the encryption keys. Rift shares by the folder and keeps the keys on your machines.

ArchilRift
IdentityArchilA disk token, an AWS IAM principal or an S3 key.RiftA key that each machine and agent makes for itself. No account.
Smallest shareArchilA whole disk for anything that mounts it. A signed link can share one file, read-only, for up to seven days. A container the account holder launches can be limited to a subdirectory or to read-only.RiftA folder, a subfolder or one file, as read or write.
Who checks accessArchilArchil.RiftEach machine that receives a file checks the grant itself.
Who can read your filesArchilArchil, which manages the encryption keys for its storage. Data synced to your own S3 bucket follows that bucket's settings. Archil's home page also lists a bring-your-own-cloud option.RiftOnly the machines you shared with. Rift Cloud holds ciphertext.

Which to choose

Choose Archil when

  • Many servers need one fast disk.
  • Your data lives in S3 and should stay there.
  • You want a managed service with an availability guarantee.

Choose Rift when

  • Another party's agent should receive one folder and nothing else.
  • Whoever stores the files must be unable to read them.
  • The other side's agent should hold its own key and need no token from you.
