nnn

nnn is a terminal file manager for users who want file operations, search and previews in a compact tool. Its broad workflow support and minimal setup are compelling, though remote mounts depend on optional utilities and there is no dual-pane view.

Overview

nnn combines everyday file handling with disk-usage analysis, batch renaming, app launching and file picking. It can copy, move, delete, archive and link selected files, so it can serve as more than a directory navigator. The project says it typically uses less than 3.5 MB of resident memory, a useful fit for machines where a lightweight tool matters.

There is no configuration file: sensible defaults get users started, with environment variables available for optional customization. That keeps setup unobtrusive, but users who want a conventional graphical workspace or side-by-side panes should choose another kind of file manager. The project describes its privacy approach as avoiding unconfirmed user data collection.

Key features

Navigation and search

Contexts, sessions, bookmarks and directory marks help organize movement between locations. Search-as-you-type, fuzzy search, string filters and regular expressions give users several ways to narrow a directory. This range is useful for terminal users managing busy file trees; it does not remove the need to be comfortable working in a terminal.

Previews, archives and plugins

Directory and text previews, plus preview plugins, let users inspect contents without treating nnn as a full graphical file browser. It can create, list, extract and mount archives. Language-agnostic plugins can extend workflows with live previews, disk mounting, file comparison or uploads, but those additions mean capabilities can depend on external tools rather than a single self-contained installation.

Remote access and dependencies

Remote mounts work through sshfs or rclone, both optional dependencies. The base program also depends on a wide-character curses library and libc; readline is optional, and some features need external utilities. Users who only need local navigation can keep the setup lean, while remote workflows require installing and maintaining the relevant mount utility.

Desktop openers, shell integration and FreeDesktop-compliant trash utilities connect nnn to surrounding workflows. Optional tools include gio trash or trash-cli for trash handling and advcpmv for copy and move progress. Installation options include packages, a statically linked binary and compiling from source. The project points users to GitHub Issues and Discussions for problems, feature requests and enhancement ideas.

Pricing

nnn is free: the Free plan costs nothing and provides the open-source terminal file manager. There is no trial or paid tier to weigh against it. The BSD-2-Clause license permits use under its terms, but users who need a dual-pane layout will have to look elsewhere rather than pay for an upgrade.

Platforms

nnn supports Android, Linux, macOS and Windows. Linux and macOS are identified as supported; Windows is not, so Windows users should not assume a supported native experience. The project offers packages, a static binary and source compilation, with the precise installation path depending on the target platform.

Who it's for

nnn is best suited to terminal-comfortable users who value a small footprint, fast navigation and broad file operations without a configuration file. Its beginner and power-user quickstarts address different experience levels, but do not change its terminal-first character. Choose another tool if dual-pane browsing is central to how you compare or move files, or if remote mounting must work without installing additional utilities.

Pros and cons

Pros: File operations, search, previews and archive handling cover a wide range of work in one compact tool.

Pros: Sensible defaults and no configuration file reduce setup overhead; optional environment variables leave room to customize.

Pros: The project reports typical resident memory below 3.5 MB, favoring resource-conscious use.

Cons: No dual-pane view rules it out for users who rely on side-by-side file management.

Cons: Remote mounts require sshfs or rclone, and other integrations can depend on optional external utilities.

Cons: Windows is not identified as a supported platform, despite appearing among the platform tags.

Alternatives

Consider Alfa if its API, web and self-hosted platform options matter alongside Linux, macOS and Windows; it is also free and open source under MIT. FileManagerTUI is another free, MIT-licensed option for Linux, macOS and Windows, with its license permitting modification and redistribution, including selling copies, and provided as-is without warranty.

Rat Commander is a free, self-contained terminal file manager for Linux, macOS and Windows, with no paid tiers or usage limits stated. Newt is a free, open-source option for those same three platforms. superfile is a free, MIT-licensed, self-installed terminal application for Linux, macOS and Windows. Broot offers free MIT-licensed software for those platforms, with source and precompiled binaries. elio is free for Linux, macOS, Windows and self-hosted use, with no paid plan or usage limits stated on its page. far2l is a free GNU/GPLv2 option for Linux and macOS, but is marked beta and carries a use-at-your-own-risk warning.

Verdict

Choose nnn if you want a free, low-footprint terminal manager that combines file operations, navigation, search and previews without requiring a configuration file. Its main compromises are the missing dual-pane view and the extra utilities needed for remote mounts; readers who need either should compare alternatives before settling on it.
