Compare anything. Move what matters.

A fast, keyboard-driven folder & file comparison tool for Linux, macOS and Windows. Diff local and remote trees side by side, then migrate or reconcile them — streaming huge files, never waiting for a full scan.

Files from disks, drives and clouds folding into one reconciled set

Three modes, one engine

The same fast compare/reconcile engine, whichever way you need to work.

🔍

Compare

Explore differences manually: a lazy, virtualized folder tree with live status counts, word- and character-level side-by-side diffs, and hunk navigation.

🔁

Migrate

Reconcile a destination to a source — copy new, overwrite different, delete extra — with a dry-run plan, per-item checkboxes, and a streaming, cancellable apply.

🔀

Sync

Bidirectional reconciliation with conflict resolution, on the same engine as Migrate. You stay in charge of every decision.

Built to be fast — and honest

You never wait for a full scan, and you never copy on a guess.

⚡ Never waits

Shows the top level the instant you hit Compare and fills in as you explore. Folders you never open are never compared. Switch compare method with zero re-scan.

🌊 Streams huge files

Multi-GB files compare and copy in 64 KiB windows instead of loading into memory, and a byte compare stops at the first difference.

🔎 A real diff, at any size

Files too big to load show the differences only — changed regions with context, like git diff. Big binaries open in a hex view. No silent truncation.

🛡️ Move, verified

Migrate can delete the origin after a move — but only after re-verifying every byte landed in the destination, all-or-nothing. A partial move can never strand your files.

Roadmap

More sources — SMB, NFS, WebDAV and cloud drives, on the same engine.
AI-assisted semantic reconciliation — resolve conflicts by meaning, not just bytes.
Signed & notarized builds — code-signing for macOS and Windows to drop the install-time security prompts.
Confold Cloud — a hosted "reconcile and sync across sources, from one place" service.
