MarkText — Simple and Elegant Open-Source Markdown Editor

Introduction

MarkText is a free, open-source Markdown editor designed for simplicity and elegance. It provides a seamless real-time editing and preview experience using inline rendering, so what you type is what you see. Available on Linux, macOS, and Windows, it aims to be a distraction-free writing tool for developers and writers who work with Markdown daily.

What MarkText Does

• Renders Markdown inline as you type, combining editing and preview into one view
• Supports CommonMark, GitHub Flavored Markdown, and optional Pandoc extensions
• Provides multiple editing modes: Source Code, Typewriter, and Focus mode
• Exports documents to HTML and PDF with customizable styling
• Includes built-in image uploader with support for local paths and clipboard paste

Architecture Overview

MarkText is built with Electron and uses a custom rendering engine called Muya for inline Markdown rendering. Muya parses Markdown in real time and produces a virtual DOM that maps directly to the editing surface, avoiding the traditional split-pane approach. The editor manages state through a block-based document model where each paragraph, heading, or code block is an independent content block.

Self-Hosting & Configuration

• Download platform-specific installers from the GitHub releases page
• On macOS, install via Homebrew Cask or drag the .dmg to Applications
• On Linux, use Flatpak, AppImage, or distribution-specific packages (deb, rpm, snap)
• On Windows, use the NSIS installer or portable zip archive
• Configure themes, font, line height, and tab behavior through the built-in preferences panel

• Supports KaTeX math expressions and Mermaid diagrams inside Markdown
• Paragraph-level focus mode and typewriter mode for distraction-free writing
• Built-in table editor with graphical row and column management
