Open Source Atom Alternatives

Alternatives to Atom for all platforms with Open Source License

Visual Studio Code

Code combines the streamlined UI of a modern editor with rich code assistance and navigation, and an integrated debugging experience – without the need for a full IDE.
- Much faster, highly active development phase, more and more add-ons are added to the marketplace, open source, and cross-platform. Guest • Dec 2017 • 8 agrees and 0 disagrees
- VS Code has arguably better defaults than Atom especially with the pre-configured minimap. Atom's themes use HTML/CSS so visuals are fully configurable but that also makes it a bit slower with drawing operations whereas VS Code draws everything fast, very noticeable with the minimap which reacts practically instantly to changes. VS Code also loads faster and just feels faster in general. Otherwise, both editors offer a massive list of great features and droves of extensions. Ugotsta • Nov 2019 • 1 agrees and 0 disagrees

Notepad++

Based on the powerful editing component Scintilla, Notepad++ is written in C++ and uses pure Win32 API and STL which ensures a higher execution speed and smaller program size. By optimizing as many routines as possible without losing user friendliness, Notepad++ is trying to reduce the world carbon dioxide emissions.
- All needed features included, light weight and to the point. Good support for RtL scripts and customization. The only possible problem found is that the official builds are compiled for MS-Windows only, but it is open source, so that's no big deal breaker! vazirified • May 2017 • 12 agrees and 1 disagrees
- Notepad++ has built-in support for many languages and a great plugin system for more. crlamke • Jul 2017 • 11 agrees and 2 disagrees

Vim

Vim ("Vi IMproved") is an advanced text editor that allows syntax highlighting, word completion and has a huge amount of contributed content. Vim offers several “modes” for editing with efficiency. This makes vim a non-user-friendly application but it is also a strength. The normal mode binds alphanumeric keys to task-oriented commands. The visual mode highlights text. The command-line mode offers more tools (for search&replace, defining functions, etc.
- Vim offers unlimited customization and consumes very less memory, it supports execution of commands from vim itself and with the right plugins works almost like an ide Guest • May 2017 • 12 agrees and 1 disagrees
- While Vim is powerful, it’s not an easy replacement for a GUI-based text editor. Guest • Jul 2018 • 5 agrees and 5 disagrees
- Vim is a command-line tool, which differs a lot from a GUI app like Atom, Notepad++ or Sublime Text. Guest • Mar 2017 • 11 agrees and 31 disagrees

Geany

Geany is a small and lightweight Integrated Development Environment. It was developed to provide a small and fast IDE, which has only a few dependencies from other packages. Another goal was to be as independent as possible from a special Desktop Environment like KDE or GNOME - Geany only requires the GTK2 runtime libraries.
- Geany is easy, extremely fast, and reliable. Has a good console. Has good interaction with the shell. Is very customizable. Can be extended with lua. Has good selection of plugins. Snippets. Block editing. Code folding. Syntax highlighting. Tab completion. Everything works. File browser. Object browser. Configurable compilation and execution. Project managment. etc. Everuthing without bloating. Guest • Sep 2019 • 1 agrees and 0 disagrees
