Built-in network discovery
Finds servers & services on the local network via Bonjour — SSH, SMB, WebDAV and NFS through to Proxmox, Cockpit and NAS web interfaces. Connect in a few clicks instead of guessing host names.

- Native for Apple Silicon
- App sandbox · Keychain
- No tracking, no cloud requirement
Full speed ahead
Scroll to unfold the cockpit
This is not an ordinary file commander.
It is your control centre.
For administrators, power users and every curious mind who does not just move files but wants to understand what is happening on their system.

Why SailCommander
Everyday administration, done in a few clicks.
Open a remote file in the built-in text editor, change it and save it straight back. Mount a server, set permissions by click, browse an archive like a folder. Things that would otherwise take several steps or a command in the terminal are done right here.
Two panes, one pace
Source and destination always in view.
The classic dual-pane workflow, built for today’s macOS. Two panes, any number of tabs per side, its own history and filter per tab — operated by click and, if you like, at speed from the keyboard.
- F5 Copy · F6 Move · F8 Delete
- Live filter with wildcards & regular expressions
- Unix permissions, owner and group right in the list
- Sort by name, size, date, extension — folders first

F5→Copy selection

One abstraction for everything
Local, in an archive, in a container, on a server — the same motion.
A local file, a ZIP entry, a file on an SFTP server — and just the same in a Docker or Podman container, a Proxmox LXC, an Incus/LXD guest, a Kubernetes pod, a systemd-nspawn machine or a FreeBSD jail. Seven container worlds, and you operate every one of them the same way: copy, move, compare, view. You learn the app once — it works the same everywhere.
- Navigate into archives just like folders
- Copy & move within a server — without a detour via your Mac
- Server to server between two hosts — with SFTP including whole folders
- Drag & drop between local, cloud, container and remote
- The SSH connection stays open for 60 s after access — no signing in again

Transfer engine
Copy while you keep working.
Even large transfers run in the background with a real queue. You see percentage, bytes, time remaining and speed in real time. On name conflicts you decide per file — or once for all of them.
- Conflict dialog: overwrite · skip · auto-rename
- “Apply to all” for bulk transfers
- Several operations run in parallel in the queue
- Trash or permanent deletion — you choose
Remote & cloud
Servers, containers, cloud.
Servers, containers, cloud.
One command deck.
SailCommander speaks the protocols you need day to day — finds servers by network discovery, tunnels ports over SSH and keeps passwords & keys safe in the macOS keychain.
Server centre
Everything under control — in one place.
One window for all your servers instead of five scattered dialogs: connect, manage and retrace without switching apps. The server centre is the command deck behind every connection.
- Favourites & groups — every profile in order
- Containers — Docker, Podman, LXC, Kubernetes & more
- SSH tunnels & port forwarding
- Connection log — who, when, where to
- Certificates & host keys — at a glance

More clouds
Additional cloud storage is in preparation — the architecture for it is already in place.
PlannedSSH tunnels & port forwarding
Local and remote forwards for services behind firewalls — the virtual SSH bridge to databases, web interfaces and APIs on a distant network.
Keychain-securedPasswords & keys are stored encrypted in the system — separated by connection type.
The connection stays openAfter the last access SailCommander keeps the SSH session alive for 60 seconds — including the jump-host chain. The next click does not have to sign in again.
Favourite groupsOrganise servers into groups and set quick locations for direct access.
Container management
Seven container worlds, one file manager.
Docker and Podman via the engine API, plus Proxmox LXC, Incus/LXD, Kubernetes pods, systemd-nspawn and FreeBSD jails over SSH. Connect to a running container and browse its file system right in the pane — no docker exec, no kubectl cp, no copying back and forth.

What you get done with it in seconds
Adjust a config live
Check nginx.conf in the quick view or open it in the editor and save — it uploads back into the container automatically.
Pull logs out
Switch to /var/log and copy files into the local pane — for analysis or archiving.
Put files in
Copy a test certificate or a changed config straight from the other pane into the container.
Fix
/etc/hosts in placeExtend and save bind-mounted files — without “device or resource busy”.
Inspect images
Start a container from someone else’s image and browse its file system — instead of piecing commands together.

Linux server administration
Your server fleet, at a glance.
22 areas in one window, one shared host switch: from the fleet overview through the daily diagnosis to groups, users, volumes and security status. Everything runs over your normal SSH connection — SailCommander installs no agent of its own, it queries the on-board tools that are running on the server anyway.

Daily diagnosis
The questions that really matter in the morning.
Is everything running? Is disk space getting tight? Are security updates pending? Who signed in? Instead of piecing dozens of commands together, SailCommander reads them in a few bundled queries and puts the answers side by side.
- Fleet overview — all SSH favourites in one matrix
- Services, timers & journal — including a jump to the matching log
- Install updates — security packages or all of them, with a live log
- Groups & users — memberships and SSH keys by click
- Volumes — read ZFS snapshots, LVM and RAID status
- Security — SELinux/AppArmor, hardening check, secret scan
Never a silent “all green”
Whatever could not be read stays grey and is named — an unreachable host or a file without read permission never appears as an all-clear. Better to show a gap than a green tick that is none.
A report for tickets & handover
One click turns the fleet matrix or a single host into a Markdown report — with a timestamp, severities in words and a dedicated section for everything that could not be read.
Every prompt names the hostBefore anything is changed, the dialog states which server it happens on — no action on the wrong machine.
Lockout protection for the usual trapsThe SSH service cannot be stopped and your own administrator rights cannot be revoked — the two clicks that classically lock you out. This is not all-round protection: anyone with root rights can lock themselves out by other means too.
Reading happens as youThe diagnosis needs no root rights. For the few places that require them, the app asks specifically — never in the background.
Understand, don’t just move
See what is really happening on your system.
SailCommander answers the questions a file manager usually leaves open: where is the disk space going? What is running right now? What has changed?
Where and when will space run out?
Extensive statistics on disk usage — with a real change history based on snapshots over time. Spot trends, find old space hogs and see what struck most recently.
- Treemap & ranking of the largest folders
- Distribution by last use — “old space hogs”
- History snapshots: compare usage over time
What is running right now?
The process viewer does not leave you alone: it knows the important system services and explains what they do — instead of leaving you with cryptic names. Laid out clearly as a live process tree.
Snapshots as a basic principle
Capture states anywhere in the app — files, folders, processes, usage — and compare them with each other. See in black and white what has changed since last time.
Advanced search
File search, rethought.
Search for properties that sit in the file system but are rarely accessible: metadata, combined with AND, OR and NOT — nested as deeply as you like until the match is right.
Metadata + logic
Search criteria that go deep.
Search properties an ordinary file manager does not even know about — and combine them into a real set of rules.
- EXIF & TIFF: ISO, aperture, lens, camera manufacturer
- GPS location search with reverse geocoding
- IPTC down to press-photo fields · PDF · audio · video
- HEIC depth map · PSD colour mode · animated GIFs
- Even FITS astrophotography (celestial objects)
- AND / OR / NOT — nestable recursively

Quick view
Look inside without opening.
Put the cursor on a file — the preview appears immediately in the neighbouring pane. For almost every file type, without starting a second app.
A quick view that covers a lot
Images, PDF, audio and video — plus text, JSON, XML, YAML, archives and even FITS astro images. Unknown formats fall back cleanly to text or hex, never a blank “?”.
Markdown, rendered
Headings, lists, code and links neatly formatted instead of raw text — read documentation and READMEs right in the pane.
Metadata inspector
EXIF, GPS, Office and EPUB properties — and even the provenance: which URL it was downloaded from and with which browser, including quarantine status.

Mermaid editor
Draw diagrams — and learn Mermaid along the way.
Three routes to the same diagram: type the syntax, start from one of the templates, or simply click nodes and edges together. And that is the real trick — as you click, the Mermaid code writes itself in front of you. If you do not know the language yet, you will have picked it up after a few diagrams; if you do know it, keep typing. 20 diagram types, always with a live preview.
From Markdown to an architecture sketch
Click and learn as you go
Add, rename and connect flowchart nodes and edges through the GUI — every change appears as Mermaid code right next to it. That way you pick the language up without cramming.
20 diagram types
Flowchart, sequence, class, ER, Gantt, C4, mind map, kanban, git graph, Sankey, timeline, architecture & more — with templates for a quick start.
Work directly on the server
Open an .mmd file or Markdown containing diagrams from an SFTP server, change it and save it back — just like in the text editor.
Export & share
Export finished diagrams as PNG or SVG — for documentation, a wiki or a presentation.
Admin snippet library
Over 1,300 commands — including the ones you would never have searched for.
Sorted by topic for macOS, Debian/Ubuntu, Fedora, Red Hat, WSL and PowerShell: browsing a topic shows you what is possible at all — and you stumble across the command you would never have searched for because you did not know it existed. For looking things up day to day, for trying out and for learning. Bilingual, already built in and copied to the clipboard with a single keystroke. SailCommander does not execute the commands itself.
- Filter by platform and topic (Docker, fstab, networking, logs …)
- Create, duplicate and tag your own snippets
- CSV import and export; older JSON exports remain importable
- Live search across title, command, description and note
Use only on systems you are expressly authorised to work on. For every selected snippet the app shows notes on impact, permissions, confidentiality and third-party sources; whether a particular use is legally permissible must be checked beforehand.

Frequently asked
Good to know.
Which macOS version do I need?
SailCommander requires macOS 15 (Sequoia) or later and is built natively for Apple Silicon. It cannot be started on older macOS versions.
Is Premium a subscription?
No. Premium is a one-off in-app purchase. The price binding for your storefront is shown in the Apple App Store before you buy.
What can I do during the trial?
During the 30-day trial all Premium features are unlocked. After that, the features marked as free in the app remain usable.
Where are my server passwords stored?
Exclusively in the macOS keychain — encrypted and separated by connection type. Credentials are only transmitted to the destination you have chosen, or during OAuth sign-in directly to the respective provider, never to Crazy Softworks.
Does the app collect data about me?
No. There is no tracking, no advertising and no account requirement. Local work stays entirely on your Mac.
Can I copy directly from server to server?
Yes. You copy files from one server straight to another — with SFTP/SSH servers, whole folders too. You only specify source and destination; SailCommander handles the transfer in one go via your Mac. Within the same server the copy even runs server-side — with no detour at all.
Set sail.
Download SailCommander and bring order to local, remote, cloud and container files — in a single, fast app.
