Charon v0.1.0

Charon 0.1.0 — first crossing

The ferryman for your files. Charon keeps folders and drives in sync: mirror, backup or two-way, by hand, on change, on a schedule or the moment a drive is plugged in. Nothing is lost on the crossing.

Three ways to cross

• Mirror: the destination becomes an exact copy of the source.
• Backup: new and changed files are copied, and nothing is ever deleted on the destination.
• Two-way: changes flow both ways. Charon remembers the last synced state, so it can tell "deleted here" from "new there".

Four ways to start

Manually, a few seconds after changes settle, every N minutes or daily at a set time, or as soon as the drive is connected.

Built to be trusted

• Preview before you sync: a dry run shows exactly what will be copied, replaced and removed. New jobs open it by themselves.
• Safe deletes: removed and overwritten files go to a .charon-trash folder for 30 days (configurable).
• No half-written files: every file is copied under a temporary name and only takes its real name once it's complete.
• Stops before disaster: if one side is suddenly empty (an unmounted drive, a wrong folder), Charon refuses to wipe the other.
• Conflicts are never silent: keep both, newest wins, or ask you. An edit always beats a deletion.
• Exclude filters, with sensible defaults (.DS_Store, Thumbs.db, …).

And also

Menu bar / system tray icon with Sync all and Pause everything, notifications for errors, conflicts and big syncs, launch at login, a per-job activity log, and status colours with icons that stay readable for colour-blind eyes. No accounts, no cloud, no tracking.

Downloads

System	File
macOS 11+ (Apple Silicon)	Charon-macOS-Apple-Silicon.dmg
macOS 11+ (Intel)	Charon-macOS-Intel.dmg
Windows 10/11	Charon-Windows-Setup.exe or Charon-Windows.msi
Linux	Charon-Linux.AppImage, .deb (Debian, Ubuntu) or .rpm (Fedora, openSUSE)

First start: the macOS app is signed and notarised by Apple. The Windows installers aren't signed yet, so if SmartScreen asks, choose More info → Run anyway. On Linux, the tray icon needs AppIndicator support (on GNOME: the "AppIndicator" extension).
