The source code editor your Mac deserves.
A native Mac text editor for developers, security professionals, and power users. 50+ languages. Multi-tab. Fully offline. One purchase — no subscription, no account, no telemetry.
macOS 13 Ventura or later · Apple Silicon & Intel · One-time purchase
Tab.Noted detects your language from the file extension and applies full syntax highlighting — no setup, no plugins. From Swift and Python to YARA rules, Suricata signatures, HCL, Protobuf, and Jinja2. Seven built-in themes. A custom theme builder for the rest.
Web · Systems · JVM & .NET · Scripting · Shell & Build · Data & Config · Security · and more
Tabs that resize fluidly as you open more. Drag to reorder. Pin the ones you always need — pinned tabs survive app restarts even without being saved. Quick Open (⌘P) gets you anywhere without touching the mouse. Your workspace comes back exactly as you left it.
Save named sets of open tabs and switch between them instantly — one group for each project, investigation, or context. Each group remembers and restores its own tabs, so jumping between work never means rebuilding your setup. New Tab Group is one shortcut away (⌘⌥T).
Regex support. Whole-word matching. Case sensitivity. Select all occurrences at once. Search across every open tab with ⌘⇧F, or sweep an entire folder from disk. Replace All is fully undoable.
Macro recording and playback. Snippet expansion. Clipboard history — paste anything you copied, not just the last thing. Column selection. Move lines. Sort, deduplicate, and trim. Case conversion. Toggle comments for every language. All built in, nothing to install.
Minimap for long files. File browser for your project tree. Integrated terminal. Hex editor for binary inspection. Markdown preview. Side-by-side file diff. JSON tree viewer. Document statistics. All included — no extensions required.
No account to create. No analytics running in the background. No subscription expiring. Tab.Noted doesn't know who you are, and it doesn't need to. Your files stay on your device. The app works completely offline. Pay once — it's yours.
Already planned for upcoming releases:
macOS 13 Ventura or later. Tab.Noted runs natively on both Apple Silicon (M1/M2/M3/M4) and Intel Macs.
Yes, entirely. No internet connection is ever required. The one exception is Markdown preview, which loads syntax highlighting from a CDN on first render — it works offline but renders plain without internet.
Any plain text file. Tab.Noted recognizes 50+ languages by file extension and applies syntax highlighting automatically. It can also open any file in the hex editor.
Only file-backed tabs (tabs with saved files) restore on relaunch. Untitled tabs that were never saved cannot be restored. When you quit with unsaved untitled tabs, Tab.Noted will prompt you to save them before closing.
