Notepad++

G2 Rating: 4.6 out of 5 stars
Notepad++ is a free, open-source code editor that’s specifically designed for novice programmers. Like other code editors, it offers syntax highlighting and autocorrect. What sets Notepad++ is how many languages it supports, how many files you can load and work on simultaneously, and how lightweight it is. In addition to HTML and CSS, Notepad++ supports 75 other programming languages. You can open up different file formats in these different languages at the same time and make edits without having to worry about using a ton of CPU power or causing slow load times.
Some limitations make this editor less than ideal for some users. First, Notepad++ only works for Microsoft Windows. That means, if you’re working on any other operating system, like macOS for example, then you’ll have to use another editor. Second, Notepad++ does not offer support for git. If you want to push code to a repository inside your editor, you’ll also be better off using an alternative.
Pros
- Free and open-source
- Lightweight and fast
- Supports a wide range of programming languages
Cons
- Only available for Windows
- Somewhat outdated interface
- No git integration
Price
Notepad++ is free.
Sublime Text

G2 Rating: 4.5 out of 5 stars
Sublime Text is like the Notepad++ for macOS users with sophisticated needs. It’s compatible with multiple programming languages like Notepad++. It offers the standard features that Notepad++ offers — and so much more, including cross-platform support, split editing, and multiple-selection editing. In exchange for this power and flexibility, you’ll have a steeper learning curve.
For example, you can use a variety of keyboard shortcuts to quickly execute tasks in Sublime Text — as long as you can remember them. You can customize virtually everything in the editor, from key bindings to menus to snippets and more — as long as you have the time.
All of these features are included in the free version of Sublime, but this version eventually starts displaying popups prompting you to purchase a premium license.
Pros
- Sleek, simple, user-friendly interface with customizable color coding
- Split-screen editing and multiple-selection editing
- Built-in file organizer for easy navigating and locating
Cons
- Only available for macOS
- Paid version is pricey; free version occasionally prompts you with pop-ups to purchase the full version
Price
Sublime Text is available as a free version, or you can purchase a license for $80.
