flow

Keep two directories in sync, nothing more.

flow is a single binary that mirrors one directory onto another over SSH. No daemon, no database, no account.

Install

curl -fsSL https://flow.artalpion.uk/install.sh | sh

Use

flow push ./site user@host:/srv/site
flow pull user@host:/srv/site ./site
flow watch ./site user@host:/srv/site

Why

• One file, no runtime dependencies.
• Delta transfer — only changed blocks go over the wire.
• Dry run by default when the target is not empty.

Status: maintained, slowly. Issues are handled by e-mail.
