Editorio

Text, Markdown & Code Editor

Only for Mac

Free

Mac

Editorio is a native macOS text editor for markdown, code, and plain text. Built entirely with AppKit — no Electron, no web views, no Chromium. Just a fast, focused editor that opens your files and gets out of the way. MARKDOWN PREVIEW Open any markdown file and see it rendered instantly with styled headings, formatted code blocks, clickable links, tables, task lists with checkboxes, blockquotes, and footnotes. Full support for CommonMark and GitHub Flavored Markdown (GFM). Toggle between Preview and Source mode with Cmd+U. Preview shows your rendered document. Source shows the raw markdown with syntax highlighting and line numbers. The switch takes less than 16 milliseconds — one frame. SYNTAX HIGHLIGHTING FOR 180+ LANGUAGES Editorio highlights Swift, Python, JavaScript, TypeScript, Go, Rust, C, C++, Java, Kotlin, Ruby, PHP, HTML, CSS, SQL, Bash, YAML, JSON, and over 170 more languages. Open any source file and the correct grammar is detected automatically. BUILT FOR SPEED Files open in under 100 milliseconds. Scrolling runs at 60 frames per second with native scroll physics — no frame drops. The app launches in under 500 milliseconds. Memory usage stays around 35 MB. These aren't marketing numbers. This is what happens when an editor is built with native frameworks instead of a web browser. THEMES Four built-in themes: Default Dark (Monokai-inspired), Default Light (Sublime-inspired), Nord (Arctic palette), and Solarized Dark. Switch themes instantly from the status bar or from Preferences. Editorio can also follow your system appearance and switch between light and dark automatically. MINIMAP A Sublime Text-style scrollable minimap on the right side of the editor gives you a bird's-eye view of your document. Click or drag to navigate anywhere instantly. Toggle it with Cmd+M. DETAILS THAT MATTER • Native macOS tabs — open multiple files in one window with Cmd+T • Window state persistence — size, position, and zoom level are remembered • Export to PDF with Shift+Cmd+E • Print support with proper page breaks • Full-screen mode • Zoom in/out with Cmd+Plus/Minus • Line numbers in source mode • Status bar showing language, word count, encoding, and editing mode • File type associations — double-click .md files to open in Editorio SUPPORTED FILE TYPES Markdown (.md, .markdown, .mdown), Swift, Python, JavaScript, TypeScript, Go, Rust, C/C++, Java, Kotlin, Ruby, PHP, HTML, CSS, SCSS, JSON, YAML, TOML, XML, SQL, Shell scripts, and plain text files (.txt, .log, .conf, .ini, .env). COMPLETELY FREE Editorio is free with no trial, no feature gates, no time limits, and no in-app purchases. Every feature works from day one. No subscriptions, no upgrades, no paywalls.
