Fast, minimalist and lightweight editor with zero noise.
moco is an open-source editor built with a simple idea: do your job fast and stay out of your way.
No bloat. No extra panels. No heavy background processes.
Only what you actually need.
moco is a lightweight desktop editor that:
- Launches instantly
- Uses minimal memory
- Doesn't distract with unnecessary UI
- Supports local folders and SSH/SFTP remote connections
- Does exactly what it's meant to do
It's for those who value speed, simplicity, a clean interface and minimalism.
Minimum code. Maximum performance. Zero visual noise.
moco doesn't try to be "everything at once". It does one thing — and does it well.
- Multi-format Support: Syntax support for dozens of popular programming, markup, data, configuration, and documentation formats, with an extensible format registry
- Built-in Formatters: Instantly format or minify supported files using Prettier and purpose-built parsers where appropriate. Embedded code and common real-world minification artifacts are handled automatically
- Optional Auto-save: Disabled by default and available in Settings. After a short editing pause, moco saves the current editor text without applying manual whitespace cleanup
- Maximum Optimization: An optional large-file mode that reduces and pauses non-essential background features, keeping the editor focused on responsive editing and manual saving
- Manual-save Whitespace Cleanup: Enabled by default and configurable in Settings. Explicit saves from the toolbar or
Ctrl+S/Cmd+Sremove trailing spaces and extra blank lines at the end of the file; auto-save never applies this cleanup - File Tree Sidebar: Open a local folder to browse and edit files quickly
- SSH/SFTP Support: Connect to remote servers, browse their file system, edit and save directly
- Smart Encoding: Auto-detects Unicode and common legacy file encodings for reliable display
- Markdown Preview Modes: Switch between the editor and a full read-only preview, or use side-by-side mode with the editor on the left and a live preview on the right. Scrolling is synchronised in both directions, including for long documents and large tables
- Markdown Link Handling: External links open in your default browser; local file links open in the editor if the file exists, or show a "File not found" notice without leaving the current file. Paths with spaces work correctly
- Keyboard Layout Correction: Select text typed with the wrong keyboard layout and convert it between English and the layout associated with the current UI language without retyping (
ghbdtn→привет). A sensible fallback layout is used when the UI itself is in English - File Navigation History: Back and forward buttons for recently opened local files; the sidebar follows the current file's directory
- Recent and Pinned Files: Keeps recently opened local files within easy reach and separates pinned favourites from the rest. Use
Ctrl+Click/Cmd+Clickto open an entry in a new moco instance. SSH files are never added or pinnable - Recent File Switcher: Hold
Ctrlto show up to five recently opened files, then pressTabto cycle through them and releaseCtrlto open the selected file - Live Status Bar: Shows essential file metadata, save state, editing statistics, an exact
o200k_basetoken count calculated off the main thread, and cursor information - App Settings: Configure appearance, interface language, editor behaviour, saving preferences, and other supported options. Settings are stored in
settings.jsonnext to the executable and shared across all open windows; the current moco version is shown in the dialog - File Type Badge: Toolbar shows a compact coloured badge based on the current file extension
- Full UI Theming: The selected theme applies consistently across the entire interface
- Welcome Screen — Create File: Pick a path and name in the save dialog; moco creates an empty file and opens it in the editor
- Welcome Screen — Stored Files: Pinned and recently opened local files use the same reusable list as the toolbar dialog, including pin controls and new-instance opening
- Per-File Undo: Ctrl+Z undo history is scoped to the current file and resets when you switch to another file
