Category overviewAbout Shell EnhancementsRead guide

Small programs that make the shell you already use faster to work in. Nothing here is a platform, nothing here needs a procurement conversation, and all 30 indexed tools are open source and free without exception.

Start with the honest caveat, because it changes how you should read the page: none of these 30 tools carries a scored review on this site yet. Where other categories let you sort by a number, here you are choosing on fit, and the only signals we can offer are how often a tool appears in our 131 published stacks and what its licence says.

The 27 tools currently shown split into four jobs.

Faster replacements for a builtin you already know. ripgrep for grep, fd for find, bat for cat with syntax highlighting, eza for ls, zoxide for cd with frecency. These are the highest-return installs because there is no new mental model — the muscle memory transfers and the speed difference is immediate. fzf sits alongside them as the fuzzy finder that everything else pipes into.

A layer above the shell. tmux keeps sessions alive across disconnects and is in 5 of the 131 stacks, more stack membership than anything else we rank in this category. Zellij is the newer take, with batteries-included defaults. lazygit and lazydocker put a terminal UI over git and Docker rather than replacing the CLI.

The shell and its prompt. zsh, fish and Nushell are the shells themselves; Nushell is the interesting one because it carries typed, structured rows through pipes instead of plain text. Starship, Oh My Posh, Oh My Zsh and Oh My Pi configure what you look at. Atuin replaces shell history with an encrypted, SQLite-backed store that syncs across machines — the one on this list most likely to change how you work.

A model in the shell. ShellGPT, aichat, shai, llmfit, CLI-Anything and cli-continues put an LLM behind a prompt without opening an editor. This is the newest of the four groups and the least settled.

The graveyard here is the most instructive part of the category. exa died on 1 September 2023 when its single maintainer stopped responding to issues; the community fork eza overtook it and is a live card on this page. Fig was acquired by AWS, folded into Amazon Q Developer, and discontinued as a standalone product on 19 February 2025. Charm archived Mods on 30 June 2026. All three appear in our six most recently verified records — three of six — and none of them renders in the grid. Single-maintainer burnout and acquisition are the two ways small shell utilities end, and both are visible in this category's own history.

Install two replacements and Atuin this week. Leave the rest.
