Leaf is a terminal-based Markdown previewer with an interactive interface for reading documents and an inline mode for rendered output in command-line workflows. Its official documentation describes navigation, search, live reload, code highlighting, math and Mermaid rendering, plus integrations for editors and tools such as fzf. It may suit CLI users who want to review Markdown without switching to a browser or desktop app; its feature and platform descriptions are project claims, not independent compatibility or performance tests.
What Leaf does
Leaf renders Markdown in a terminal. The project describes it as offering “a terminal-based Markdown previewer with a GUI-like experience.” That means an interactive, keyboard- and mouse-accessible terminal interface—not a browser preview or graphical desktop window. Leaf’s product site and official documentation describe the intended audience as developers, command-line users and people reviewing AI-generated Markdown.

There are two useful workflow patterns: open a document in Leaf’s interactive interface to browse it, or send Markdown through its inline mode to render output in a terminal pipeline. The latter can help when a document is generated by another command or when a fuzzy finder needs a preview.

Formatting and diagrams
The project documentation lists rendering for headings, lists, blockquotes, tables, GitHub-style callouts, task lists, text highlighting and footnotes. It also claims syntax highlighting for more than 40 languages, LaTeX math converted to Unicode, and Mermaid diagrams rendered as ASCII art. These are capabilities stated by Leaf’s documentation, not results from an independent feature or rendering test.

Browsing and finding content
In interactive mode, the documented controls include vim-like keyboard navigation and mouse support. A table-of-contents sidebar tracks the active section, and full-text search helps locate material in a document. Leaf also lists a fuzzy file picker and directory browser, which are intended to help users move between Markdown files from within the terminal interface.
Keeping a preview current
Watch mode is documented to reload a file when it changes while preserving the scroll position. That can be useful when editing a document in a separate editor and checking the result in Leaf. The documentation also describes editor integration that can open the current file externally and optionally position the editor at the line currently visible in the preview.
How Leaf fits command-line and editor workflows
Leaf can read Markdown from standard input, so another command can supply content to it. Its inline mode writes rendered Markdown to standard output, making it suitable for previews in tools such as fzf. The project also documents a Vim split integration. Together, these options let users inspect generated or edited Markdown without requiring every step to happen in a separate graphical application.
The most relevant questions when considering any terminal Markdown renderer are whether it has the interaction model you want, which Markdown features it renders, whether it supports stdin and live reload, how it connects to your editor or other CLI tools, and whether it can be installed on your operating system. The available Leaf materials document these capabilities for Leaf but do not establish comparative rankings or performance against other tools.

How to install Leaf
The official repository lists published binaries and package-manager routes including npm, Homebrew, Cargo, Scoop, and Arch Linux/AUR. The best route depends on your operating system and existing package workflow; use the repository’s current instructions because package availability and commands may change. Installation was not independently verified here.
- Published binaries: consult the repository’s release and installation guidance for available assets.
- npm: the listed package is
@rivolink/leaf. - Homebrew: the listed formula is
leaf-markdown-viewer. - Cargo: the listed package is
leaf-markdown-viewer. - Scoop and Arch Linux/AUR: follow the repository’s platform-specific directions.
The project documentation lists macOS, Linux, Windows and Android through Termux as supported platforms. These are project-stated support targets rather than independent tests across devices or configurations. The repository also documents an in-app update command that downloads a matching published asset and checks it against a published SHA256 checksums file before installation. Leaf is identified as MIT-licensed; consult the repository’s LICENSE file for the applicable terms.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Who is Leaf for?
- Consider it if you read or edit Markdown in a terminal and want navigation, search and a contents sidebar in the same environment.
- Consider it if you want a preview that can reload changed files, or rendered output that can be connected to shell pipelines and fuzzy-finder previews.
- Check the documentation first if your documents depend on particular Markdown extensions, math conventions, Mermaid syntax or platform-specific behavior; listed support is not a guarantee for every document or setup.
- Look elsewhere if needed if you specifically require a browser-based preview or a desktop graphical editor, since Leaf’s interface runs in a terminal.
