Our verdict on Sheldon

Sheldon is an open-source command-line tool for managing and loading shell plugins, aimed at people who work in Bash or Zsh and want to keep plugin sources configured in one place. Its focus is narrower than a general-purpose extensions catalog: it operates on shell plugin sources and generates shell code for loading them. The project documents Linux and macOS binaries, and its documented defaults target Bash and Zsh. That makes it a fit for solo users and small teams who manage their shell setup directly, rather than people seeking add-ons for a browser, CMS, or IDE.

Plugin sourcing is the central strength. Sheldon can work with Git repositories, including GitHub and Gists, as well as remote scripts, local directories, and inline code. A TOML file holds source configuration and options, while CLI commands let users initialize configuration and add, edit, or remove plugin entries. The tool can install and update sources, lock them, and generate the shell code needed to load them. Templates and profiles give users ways to shape configuration, while installation hooks and Bash and Zsh completion scripts support the surrounding workflow. This breadth within shell management is useful when plugin sources do not all come from the same place.

Sheldon is free and open source, with self-hosted deployment, so the published product model is a local command-line workflow rather than a hosted service. Installation options include package managers, Cargo, and prebuilt binaries for Linux and macOS. The trade-off is its specialist scope: users looking for visual extension management or support beyond shell plugins should choose a tool built for that ecosystem. Bash and Zsh users comfortable editing TOML and working in a terminal are the clearest audience; those wanting a graphical setup experience may prefer another approach.
