Atom仍处于测试阶段(在我写这篇文章时是v0.123)，但它进展很快。比Sublime快多了。新版本每周发布一次，有时甚至在同一周发布几个版本。在它短暂的生命周期中，它比Sublime发布了更多的版本，后者需要几个月的时间来发布一个新功能或修复一个错误。以下是Atom自beta版发布以来所走过的道路的最新进展:

Sublime has better performance than Atom. Simply because it's written in C++. Atom on the other hand is a web based desktop app built on top of Chromium, and while they take performance close to heart, it will be really hard or even impossible to reach the same speed and responsiveness. Last July Atom began using React and it gave it a nice performance boost but you can still feel the difference. Apart from that, if Atom’s performance issues will not push users away - Sublime better speed up the release cycle, brush up its small UX tweaks, and consider letting in more contributors because this is where Atom is winning. Atom's package ecosystem is also growing really fast, it might not be as big as Sublime's at the moment but I have a feeling that with GitHub at it's back it will keep growing even faster. It probably has the majority of IDE like plug-ins you can think of. A major difference right now is that it can't handle files bigger than 2MB so it's something to keep in mind. The one thing you'll notice first is that the Sublime minimap is gone! Other than that, the first impression is that Atom looks almost the same as Sublime. I wrote a more in depth comparison about it in this blog post. No easy straightforward way to port your Sublime configurations, packages and such as far as I know.

到目前为止还没有人指出的一个主要区别是(至少在Windows上)Atom不完全支持除US之外的其他键盘布局，这对一些人来说可能很重要。有一份关于这个漏洞的报告，几百个帖子已经开放了一年多(https://github.com/atom/atom-keymap/issues/35)。

可能与选择编辑有关。

另一个区别是Sublime文本是一个闭源项目，而Atom源代码是/将是公开可用的——尽管Github不打算将其作为一个真正的开源项目发布。他们想要提供对代码的访问权限，而不是向贡献者开放代码。

Github公开了代码:http://blog.atom.io/2014/05/06/atom-is-now-open-source.html

How is Atom different from Sublime? Atom is an open source text editor/IDE, built on JavaScript/HTML/CSS. Sublime Text is a commercial product, built on C/C++ and Python. Comparable to Atom is Adobe Brackets, another open source text editor/IDE built on JavaScript/HTML/CSS. Be minded that this makes Brackets more oriented towards Web development, specially in the front end. Advantages of open source projects are faster rate of development and, of course, price. Does it include IDE features like build tools, function definition jumps, documentations, etc.? The short answer is yes, yes, and yes. The app is completely modular. Open source will give people the freedom to fill the gaps on several of these features. Has anyone using Sublime got a Beta invitation to point out the differences? Advantages of Atom is entry-level hackability, since it's built on the same code that powers Web sites. Advantages of Sublime Text is performance, as it doesn't need to run on top of Node.js, and it's a more mature product, about to reach a stable version 3. There are a long list of minor differences that can be included in the comments (I wish this markdown could be able to draw a table for comparisons, but that's another issue). Because of Atom's rapid turnout, I am afraid some of differences I list here will become outdated over time. Per example, at the time of this writing, Atom is only available on the Macintosh while Sublime Text is already multiplatform. Can I use the themes, schemes and packages from Sublime as is, like Sublime could do with text mate. The short answer is no, but because of Atom's hackability, it will be easy to retool packages from other editors to Atom.

我尝试了Atom，它看起来真的很好，但有一个主要问题(至少在0.84版):

它不支持垂直选择Alt+拖动-这是每个现代代码编辑器必须的。

一个主要的区别是支持“印度字体”，也就是南亚脚本(包括高棉语、老挝语、缅甸语和泰国语等东南亚语言)。此外，对东亚语言(中文、日语、韩语)的支持也更好。这些是已知的错误(实际上是评分最高的错误)，已经存在多年了(东亚语言支持似乎以前工作得更好，但现在已经很难使用):
