Synchi
jakobkreft.github.io
Efficient two-way sync between local and remote roots.

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.

    Very nice! I’ll keep using unison for now as I need something stable and reliable, but I’ll keep an eye on the project and may switch to it eventually.

      Totally fair, Unison is solid and I was inspired by it a lot, but its also the reason why I started working on my own version. I was frustrated with it because on Synology/SMB filesystems it kept seeing changed timestamps as modified files, so I’d constantly get fake changes and transfers. Synchi only treats a file as changed if the content hash actually differs.

      Also, I once managed to delete my entire home folder because I tried syncing it with Unison to a server and it synced the empty remote folder back to my home, wiping everything. That’s exactly the kind of human error Synchi tries to prevent by being very explicit and verbose about what it’s about to do.

      Thank you for keeping an eye on it!
