Features

What Stuped does, and the shortcuts for it.

More than 150 languages

Syntax highlighting via highlight.js for more than 150 programming languages, with line numbers.

File tree

A sidebar with the folder's files. Folders load when opened, and changes on disk appear immediately via FSEvents.

Markdown preview

Renders GitHub-flavored Markdown next to the source as you type. Switch between editor, preview and both with ⌘1, ⌘2 and ⌘3.

Mermaid diagrams

Mermaid blocks in Markdown files are rendered as diagrams in the preview.

HTML preview

HTML files render in a built-in WebView next to the source.

Image preview

Opens PNG, JPEG, GIF, BMP, TIFF, WebP, HEIC and ICO files. Other binary files are detected and not opened as text.

Find in file

A find bar for the current file. Step through matches with the keyboard.

Git branch

Shows the current Git branch of the open folder.

Tabs

Open a single file or a whole folder, each file in a tab. Tabs with unsaved changes show a dot; right-click for more actions.

Mini-map

A scaled-down view of the file at the right edge of the editor. Click or drag to jump. Toggle with ⌘⇧M.

Recent files

⌘R lists recently opened files. Type to filter, use the arrow keys to select, press Enter to open.

Search in folder

⌘⇧F searches all files in the open folder by name, content or both. Filter by extension with ext:. Results show the path and the matching line.

Reload on change

When another program changes an open file, Stuped reloads it from disk. Tabs with unsaved changes are left as they are.

Hidden files

Show or hide dot files and folders in the sidebar with ⌘⇧H. The setting is kept across launches.

Appearance

Choose Light, Dark or System in the View menu, independent of the macOS setting. The choice is kept across launches.

Fullscreen

The green window button switches to native macOS full screen.

Reveal in file tree

⌘⇧J, or the tab's context menu, shows the open file in the sidebar.
