Nimble Commander is a real, mature, GPL-licensed orthodox file manager. The closest competitor in spirit. We don’t want to talk you out of it — if you need free and open, it’s a great choice. We do want to be clear about what you’re trading by paying us €19.99 instead.
Three preset keyboard layouts (Orthodox / macOS / Vim). Single-key Vim verbs (y / p / dd) on the Vim preset. Saved to UserDefaults; switching prompts before clobbering customisations. Nimble doesn’t document a Vim mode.
File-level Git status badges in the panes. Git Status Panel (⌘+⇧+G). Side-by-side diff against HEAD. Hunk-level merge keys (> / < / x) in F9 viewer. Nimble has no Git integration.
Twelve-permission capability model, sandboxed JS runtime, full captain.* API. No plugin system in Nimble.
Native support for Amazon S3 (with MinIO, Backblaze B2, DigitalOcean Spaces variants), Google Drive, OneDrive, Dropbox, Rackspace, WebDAV, SMB, AFP, NFS. Nimble has FTP / SFTP / WebDAV; the rest are out of scope for it.
Reads ~/.aws/credentials and ~/.aws/config, surfaces every profile in the S3 dialog. Pick one, the access key / secret / region fields fill in.
Norton Commander theme with optional CRT scanlines, phosphor glow, and period-correct system-sound effects (Tink/Pop/Funk/Basso on copy/delete/conflict/error). Plus Modern, Paper, Midnight built-in, plus user JSON themes. Nimble has Classic Presentation but no retro effects layer.
HMAC-chained admin audit log at ~/Library/Logs/CaptainsDeck/admin.log, master “Allow admin operations on this Mac” switch, auto-exit timer. Useful in shared / regulated environments.
Save a query + mode + filters by name. Click the saved search in the sidebar to re-run against the active pane. Nimble has search; not saved searches surfaced in the sidebar.
GPLv3, source on GitHub. If your hard requirement is “free and auditable,” we can’t compete. We’re proprietary at €19.99. Nimble is the right answer for that requirement and there’s no shame in it.
Years of development by Mike Kazakov. The codebase is well-tested in the wild. We’re newer.
Nimble has its own theme customisation system (different from ours). If you’ve already invested time in a Nimble theme, that work doesn’t port directly. If theming is your top priority and you don’t care about JSON specifically, both apps cover it.
Use Nimble Commander if: you want free and open source above all else, your needs are FTP/SFTP-shaped (no S3 or cloud providers), you don’t need Vim or Git in the file manager, and you’re happy theming via plist edits.
Use Captain’s Deck if: you want Vim navigation, in-app Git workflow, S3 / Drive / OneDrive / Dropbox in addition to SFTP, JavaScript plugins, an audit log, or you’d rather pay €19.99 once for a single tool that covers all of it.
There’s no shame in either choice. Some Captain’s Deck users came from Nimble; some Nimble users tried us and went back. Pick the philosophy first, the feature list second.
Install both, use them for a week, see which one feels right. €19.99 if Captain’s Deck wins.
