CotEditor for Mac © Mineko Imanishi

CotEditor is a slim but powerful editor for editing plain text files such as web pages (HTML, CSS), programme source code (Perl, Python, Ruby etc.), structured texts (Markdown, Textile, TeX etc.) and any other kind of plain text. Open source, free of charge. Archive size: only 15.9 MB.


macOS 10.15 or higher, 64-bit CPU, also Apple Silicon M1


German, English, French, Italian, Japanese, Portuguese, simplified Chinese

Specially for macOS

The application was developed specifically for macOS. The appearance and behaviour of CotEditor are exactly as you would expect from a macOS application. This means that you know how to use it right after the first start of the program. There are no complex settings files, which would require you to be a computer whiz. You access all your settings, including syntax definitions and themes, through a standard settings window.

Fast, simple and powerful

CotEditor starts very quickly and you can get started straight away. It is perfect for writing a draft version for your document or quickly writing some code. The simply structured user interface does not distract you from your task. CotEditor is neither software just for beginners nor a typical minimal “Zen-style” editor. It is fully customisable. Functions for syntax highlighting for various languages, for searching and replacing with regular expressions and for automatic indentation are of course available. A command line tool and many other in-depth functions are also provided. You can easily write your own macros in your preferred language.

Main Functions

  • Syntax highlighting with over 50 preset languages
  • powerful search and replace with regular expressions
  • automatic backup with/without overwriting actual document files
  • display of the line numbers
  • live count for characters/words/lines
  • careful handling of file coding and line endings
  • automatically generated overview menu for quick navigation
  • editing with multiple cursors

  • Search & Replace does not distinguish between upper and lower case!

Note: You can use Textastic for iPad and iPhone to synchronize files between the Mac and iOS version of Textastic with iCloud. More secure: Use SFTP / SSH for this! This Mac version lacks the FTP client, but the iOS version includes a FTP client! Tip: use it with FileZilla on the Mac!

Tip: try CotEditor before Textastic! It doesn't have an FTP client either, but otherwise it has no shortcomings. It has a lot more features like Notepad++ for Windows. But if you don't like CotEditor, buy Textastic!

Notepad++ for Windows © Don Ho

Text Editing to go

John T. Haller from New York bundles Notepad++ with his launcher for portable Applications to Notepad++ Portable.
On the website of the software developer Don Ho, there is Notepad ++ as a ZIP file and as a 7-Zip file to unzip to a file folder, from which Notepad++ starts directly and runs without a Windows installer. I have tested this on 22.06.2018 and since then I use this version directly from the Developer.

  • User Language Defined System
  • tabed document and Multi-View
  • more than 50 languages supported
  • full drag and drop supported
  • Macro recording and playback

  • best file manager since Norton Commander in the nineties
  • best file manager under macOS for efficient work
  • File archives can be operated like folders, i.e. no unpacking first and packing afterwards
  • Pro version supports MTP, i.e. copy data to and from Android smartphone/tablet


  • For its integrated FTP client, I would still like the date and time of the files to remain unchanged during copying, as with FileZilla (adjustable)


This file manager is good for your nerves if you are a Windows convert and have been despairing of Apple's Finder ever since …
Since the early days of no-name PCs, I have screwed them together as a hobby and used Norton Commander to manage thousands of files. Later I found Marek Jasinski's FreeCommander as a modern alternative.
Since 18.05.2020 I have been a macOS user and had “withdrawal symptoms” – I was desperately missing a proper file manager!
On 16.05.2021, I found Commander One Pro by searching again and gladly paid the 32.99 EUR for a comprehensive file manager that handles the efficientest unpacker formats e.g. 7-Zip and RAR and includes an FTP client. I could have got it for free as “Commander One” without the FTP client and the efficient pack formats, but it is precisely these additional functions that matter to me as a website operator!

23.06.2021: Have made a feature request to the developers because of the disadvantage of the ftp client mentioned above as Cons.
16.02.2022: Because I only received a standard reply to my ticket, I tried again today.
I will write here if and when the support will get back to me.
