Marta vs nnn: keyboard-first file managers compared

Marta and nnn appeal to the same brain: keyboard-first, vim-aware, scriptable, minimalist. They land on different sides of the GUI/TUI line. The right choice depends on where you live (GUI session or terminal session) more than on the tools themselves.

TL;DR

• Marta if you want GUI workflows on macOS with vim-influenced keyboard navigation.
• nnn if you live in a terminal, especially over SSH.
• Both if your daily work spans both contexts (most heavy users).

Side-by-side

Where Marta wins

Native macOS integration

Drag from Marta into Slack, email, browsers. Drag from web browser to Marta. macOS tags, Quick Look, system sharing.

nnn runs in a terminal — none of this works.

Mixed-media preview

Marta previews images natively. nnn requires plugins for image preview, and the terminal-graphics setup is fragile.

For workflows that mix code with screenshots, design assets, or AI-generated images, Marta's preview is functional out of the box.

Dual-pane visual layout

Marta shows two panes side-by-side simultaneously. nnn shows one workspace at a time (you can switch between 4 workspaces but not see them at once).

For "copy from A to B" with both visible, Marta is the natural shape.

JavaScript plugins

If you want to write a complex custom command (parse a config, query an API, build a multi-step workflow), JS is more pleasant than shell scripts. Marta's JS API is well-documented.

nnn's shell scripts win for one-liners; Marta's JS wins for anything beyond that.

macOS-aware features

Marta knows about macOS tags, Spotlight, default applications, the file association system. nnn deals with files generically.

Where nnn wins

Terminal speed

nnn is instant. There's no GUI overhead. On slow remote SSH sessions, terminal speed feels qualitatively different from any GUI.

SSH / remote workflows

nnn over SSH is a daily workflow for many sysadmins and devs. Marta can't do this — it's a Mac GUI app.

Cross-platform

nnn runs on Linux servers, macOS workstations, BSD, anywhere. Same binary, same keys. For environments where you want one tool everywhere, nnn wins.

Smaller footprint

50KB binary, <5MB memory. Runs on a Raspberry Pi or an ancient Mac without complaint.

Shell-script plugin ecosystem

The plugin ecosystem for nnn is older and broader. Shell scripts are easy to port between machines and easy to write quickly.

Workspaces (toggle between 4 contexts)

nnn's 4 keyboard-switchable workspaces (Alt+1-4) let you jump between contexts fast. Marta's panes are simultaneously visible but capped at 2.

For "I'm working on 4 things and want to flip between them" — nnn's workspaces with full-screen attention each may actually beat seeing all 4 partially.

Where they're tied

• Both serious about vim-influenced keyboard navigation.
• Both deliberately minimalist.
• Both have active small communities.
• Both free at the entry tier.

Use case routing

The combo most heavy users settle on

- Marta in the dock for GUI workflows
- nnn in a terminal pane (or tmux/cmux session) for terminal work
- Either Yazi or ranger as a backup for nnn (taste)

These tools don't compete; they're complementary tools for different parts of the same workflow.

Where mq-dir fits

mq-dir is a different shape than either Marta or nnn — quad-pane GUI, mac-native, religious state persistence, opinionated about parallel work. It overlaps with Marta in the "Mac GUI keyboard file manager" niche but takes a different position.

If you want native macOS feel and quad-pane parallelism, mq-dir. If you want vim purity and dual-pane heritage, Marta. If you live in terminals, nnn (or Yazi).

Verdict

Marta and nnn are not really competing — they're tools for different sides of the GUI/TUI line. Most serious developers benefit from running one of each.

If forced to pick a single tool:

• Mostly GUI workdays: Marta.
• Mostly terminal workdays: nnn.

Both are excellent at their respective positions. Both safe long-term bets in 2026.

If you're considering mq-dir as a third option for Mac-native GUI but want quad-pane (Marta is dual-pane only), check the mq-dir vs Marta post separately.
