CotEditor is a plain text editor made only for macOS, and it feels like a natural part of the system from the first launch. It opens files quickly, colours code for many languages and stays light even with large documents. Writers use it for notes and Markdown, while developers use it for source code and config files where a full development environment would be slow and heavy.

Key Features

  • Syntax colouring for a wide range of programming and markup languages
  • Fast startup and a light footprint, even with large text files
  • Split editing, so two parts of a document stay visible side by side
  • Find and replace with regular expressions and saved search patterns
  • Outline menu for jumping to headings and functions, plus many editor themes

How to Download

  1. Open the official site and choose the Mac App Store edition or the direct download. Download from the official site
  2. If you picked the direct download, open the disk image and drag CotEditor into Applications.
  3. Launch CotEditor and open any text or code file to start editing.

System Requirements

The CotEditor project states that version 7.1.3 needs macOS 26 or later. The project site also keeps earlier releases for older macOS versions, so older Macs can still run a matching build.

FAQs

Is CotEditor free?

Yes. All CotEditor features are free. The Mac App Store edition offers optional purchases for people who want to support the project.

Does CotEditor work for coding?

Yes. It colours syntax for many languages, shows line numbers and invisible characters, and handles code files with ease. It is an editor, not a full development environment.

What if my Mac runs an older macOS?

The project archives page lists the last supported CotEditor release for each older macOS version, and those builds remain available to download.
