Description

CotEditor is a light-weight, neat, yet powerful text editor designed for editing plain-text files such as web pages (HTML, CSS), program source codes (Python, Ruby, Perl, etc.), structured texts (Markdown, Textile, TeX, etc.), or any other kind of plain-text.


Just For Mac

The application is exactly made for macOS. CotEditor looks and behaves just as macOS applications should. It means, you already know how to use it even on the first launch. There are no complex configuration files that require geek knowledge so that you can access all your settings including syntax definitions and themes from a standard preferences window.

Quick, Easy, and Powerful

CotEditor launches so quick that you can write your text immediately when you want to. It's perfect for you to write a draft version of your document or a scratch code. The simply organized user interface doesn't disturb your task. However, at the same time, CotEditor is neither a software only for beginners nor a typical minimal “zen-style” editor. It is fully customizable. There are, of course, syntax highlighting feature for various languages, find and replace with the regular expression, auto-indentation, command-line tool, and lots of other deep functions. You can also easily write your own macro in your favorite languages.

Customer Reviews

Easy to use

I am new to HTML and CSS on Mac and I found recommendation of CotEditor online. Just downloaded it and gave it a try; it has very simple design and is very easy to use, especially I guess for people like me who has no demanding task on HTML and instead only need to maintain personal website from time to time. I would recommend this to all light users but not sure if it is good for hard-core web developers.
