Two-way file sync, no remote agent needed

Today Synchi is finally public! It's designed for syncing files between two locations (local or over SSH). It detects conflicts, and lets you decide what to do.

Why not rsync/Unison/Syncthing?

  • rsync has no memory between runs and is one-way
  • Unison needs to be installed on both sides
  • Syncthing requires always-on daemons

Synchi runs on demand, works over SSH, and only transfers what actually changed.

I use it daily for syncing a shared folder between my machines and an android phone. Works great in combination with Tailscale/WireGuard so that you can sync files remotely.

Nothing wrong with that at all! You can set up a cron job to run Synchi every 5 minutes and it would work just fine. The only minor downside is some wasted compute since it rescans and hashes everything each run, even if nothing changed. For most files like text it's negligible though.

In the future I might look into a lightweight daemon that uses Linux filesystem notifications (inotify) to trigger a sync when something changes.
