Orbit

Total Commander for the Mac. Every disk, server and cloud drive, side by side.

// the problem

Finder has no dual pane, no keyboard-driven batch operations, and no built-in SFTP, S3 or cloud browsing. Total Commander has all of that, but only on Windows.

Orbit brings that workflow to macOS natively, with its own protocol clients instead of relying on OS mounts.

// its own protocol clients

SFTP runs on a patched SwiftNIO SSH, with Ed25519/ECDSA/RSA keys, PuTTY .ppk v3, 2FA and SCP fallback.

FTP/FTPS is written from scratch on NIO, with TLS session reuse and server-to-server FXP copy.

No OS mounts. It works the same inside the App Store sandbox.

// every backend, one f5

Local disks, archives, SFTP, FTP/FTPS, WebDAV, S3 and cloud drives all open as panes. Every backend implements one provider protocol, so one copy engine copies between any two.

// fastest copy that works

For each copy the engine tries rename, then a server-side copy, then an APFS clone, then streaming. Files are written to a temporary name and renamed into place atomically. Pause, resume, cancel and retry with backoff.

// archives as folders

Reads 15+ formats with libarchive built from source and patched for 7-Zip AES-256. Handles encrypted multi-volume RAR, archives inside archives, and blocks path-traversal entries.

// fast on 100k files

File names are turned into byte sort keys once and compared with memcmp. Measured on 100k items: sort by name in 25 ms, filter in 2 ms. F3 view memory-maps local files and reads remote files in ranges.

// every action is a command

About 300 commands, shared by menus, the F-key bar, a fuzzy command palette, AppleScript and App Intents. Keymap presets for Mac, Total Commander, Windows and Dolphin.

// power tools

Total Commander-style multi-rename with regex, EXIF fields and undo. Folder sync between any two backends. Remote edit that re-uploads on save. Finder Sync and File Provider extensions.

// architecture

[Core] → VFS → Providers → Operations → Commands → Features → [UI / App]

Core / VFS Provider protocol, paths, typed errors, a fault-injecting test provider

Providers/* One package per backend, and providers never import each other

Operations Copy engine actor: queue, conflicts, undo, verify after copy

Features/* 20 model-only modules (rename, sync, search, view, hash…), no AppKit

UI / App The only modules allowed to import AppKit, with one composition root

// rigor

→ 2,400+ Swift Testing cases across 47 packages; warnings fail the build
→ Docker test lab with ~13 live servers: OpenSSH variants, vsftpd, ProFTPD, WebDAV, MinIO
→ CI checks the import graph, licences and entitlements, plus performance gates
→ 120+ architecture decision records
