greymd

greymd is a lightweight, zero-dependency local server that renders Markdown files to HTML in real time, giving writers, developers, and documentation teams a friction-free way to preview content without installing bulky runtimes or configuring complex toolchains. Written in portable shell script, the utility spins up an ephemeral HTTP endpoint on any folder containing .md files; every save instantly refreshes the browser, so slide decks, API docs, note collections, or changelogs can be proof-read with full CSS styling and anchor navigation exactly as they will appear when published. Because it ships as a single executable with no external libraries, greymd fits naturally into portable thumb-drive toolkits, classroom laptops, CI pipelines, or offline field workstations where Node, Python, or Ruby may be unavailable or prohibited. Users invoke it from PowerShell or Command Prompt, map custom themes through simple environment variables, and share the local URL across a team network for collaborative review sessions. The unobtrusive server shuts down when the terminal closes, leaving no background services or registry entries, making it equally suitable for one-off homework assignments and enterprise knowledge-base maintenance. greymd is offered for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always providing the latest build and supporting batch installation alongside other utilities.
