CodeRunner 2 App Reviews

17 add

Useful

I use it since years. Really useful when I want to test algorithm on different language. Really efficient and easy to use.

Very disappointed

I thought it would be a useful tool. But I found this app always sort paths in $PATH in a wrong way. Completely unusable and no response from support channel.

Go-To App for so many things...

I started using CodeRunner 1 a few years ago during my studies and it has been a wonderful app. This won’t replace a full-blown IDE, but its simplicity and quickness are wonderful. You should get CodeRunner 2 if you are…: …learning to program, because it requires no setup like most IDEs do. You can easily & quickly play around and enjoy your journey into programming languages. …teaching peope how to programm. No UI Clutter, no bulky interfaces. Just you and your code. …a developer. Developing algorithms and playing around with code in a separate environment is very useful. And for me Version 2 is an improvement in any way: - break points are a game changer - improved UI and autocompletion - NO MORE TROUBLE with SANDBOXING. The transition between the AppStore purchase and the downloadable version was painless and silky smooth. Thank you! <3

Perfect if you know what to use it for

CodeRunner is a hybrid approach between a full IDE and a basic text editor. Its a small, light weight, clutter free app and yet it packs tons of features under its hood. It has not only syntax highlighting for pretty much all major languages, but also supports code completion for most of them. if that werent enough it also allows you to easily run and debug programs. Other tools like sublime text, atom or vscode are heading in a similar direction. What these three alternatives have in common are: Plugins. CodeRunner does not support something like this. This is a problem if you really want to set up your software to work with on larger projects. CodeRunner doesnt offer the flexibility to do just that. And yet I believe theres a huge opportunity for CodeRunner. Its absolutely perfect for projects that require between 5 seconds and 5 days of work. If youre a full time Python developer CodeRunner probably wont be the editor that you do your Python coding in. But it just might be the application for every other side project you might have. Its just super easy to use. Open your project no matter what its written in and run it, debug it, test it, change a few lines and fix it. Done. There is absolutely nothing to setup. It just works out of the box with pretty much all programming languages. I also want to recommend CodeRunner to computer science students. If you have multiple assigments in different programming languages CodeRunner is a huge time saver. You probably dont want a full IDE for all your weekly projects, but you also dont want to miss out features like running, debugging and code completion. The other 3 apps i mentioned arent really great either. Theres just too much of an overhead for setting up Atom or VSCode with all the plugins and settings you need. CodeRunner is nothing like that. Again, it just works. I read another review recommending this programm for teaching classes. Totally! Because there is no setup time to get everything running. Get CodeRunner if you have these side project that take a couple of days of your time. You’ll be amazed how fast you can get coding with it.

Good, not Great

It’s refreshing to have a text editor that’s ALSO an IDE… but while CodeRunner 2 has plenty of helpful code completion, there isn’t much in the way of code validation that I’ve come to expect from other editors. The app is Good… but not yet Great. Add options to run code through corresponding language LINTERS, or even continually run code through the linter, and I’m happy to endorse this general-purpose editor to any of my development community members.

Excellent tool

This tool is indespensible for development. I’m a long time user of version 1, and version 2 is a huge improvement.

Superb update to essential app

The first version of Code Runner was an essential app for quickly writing and testing code snippets, but version 2 takes the app to a whole new level. It turns Code Runner into a top-notch, lightning-fast IDE. So many thoughtful touches make it a delight to use. For example, create a new HTML document and the app initializes it with a boilerplate HTML5 template (which you can replace with XHTML or HTML4 if that’s what you need). “Run” an HTML snippet and it shows a browser preview with live updating. The app supports file browsing with a sidebar, multiple and custom themes, a myriad of languages, awesome code completion (including jQuery as well as standard JavaScript) with documentation! It’s hard to imagine a developer that wouldn’t be delighted with this app.

My Secret Weapon, now my main editor

For years Coderunner has been my secret weapon when developing and testing scripts generally, and php scripts specifically. With the latest updates, this app has become a truly fully-fledged, light-duty editor that has become my main editor for coding. The improved color-coding, brace matching (a feature no one writing most c based languages can do without), and completion, amongst other useful additions, coupled with the ability for me to test scripts in-situ quickly and easily, has compelled me to move coderunner 2 to first in my editor lineup. Most editors get in my way, or have some kind of glaring omission (brace matching being the most common) that limits their usefulness. So far, Im rocking this one! Simple, effective, with the tools I need to do the job.

One of the best

For a long time now, I have been looking for a nice code editor. I mostly do python, and from my perspective this app is great. Good code completion, nice UI, everything I would ever want. And if I need to use another language, well there are so many supported that I will use it for a long time. The Command + R and Command + . are great, because that is the same as Xcode, and using 2 IDE’s can be confusing if there are different shortcuts. In all, this isn’t an Xcode replacement, but for other languages, this is a must have.

Doesn’t Compile Swift

I owned the original version and now bought the new version. CodeRunner says it runs swift but it does not. After verifying xcode tools setup, I tried the default setup then changed to the method on the coderunner web site and tried various alternatives found on the web. I’ll have to use playground.

C# programming

I have been searching for a program that could compile C# and i have finally found it!! thank you!!

Limited because i bought it from the app store???

I basically can’t write anything in python 3, everytime I try to run it i get an error saying something about how i need to buy this app from the website because appstore version isn’t capable. I feel like i wasted my money since i can’t even write simple programs with it. I would not recommend.

Great if it worked.

Judging by the description, this is exactly the kind of program I want. Unfortunately, it hardly works. It refuses to except my specific Python executable, despite setting it up properly in the language settings. It always uses its internal Python, which doesn’t have my libraries. It has an option for invoking the bash_profile, but it doesn’t work. None of the variables, aliases, etc. that I have in my bash_profile are visible to Coderunner (tried running a simple bash script within it to echo variables). Even if these things did work, Coderunner freezes about every fourth time I click “Run.” I must force quit to get out of it and of course, I lose all my work. Finally, support is non-existent. I emailed the developer a week ago, no response; their “support” page has two FAQs; and despite being #1 in the app store developer category, Googling for help comes up with a scant few stack overflow responses on issues unrelated to the numerous ones I have. Great vision, poorly executed. I’ll come back when it works as intended. And I really want to.

Great but it keeps crashing

This is a great app however it keeps crashing on me. At first is was fine, but now I can’t even open the app.

Exactly what I needed

So far I have not experienced any issues with this. It is the perfect tool for HTML, CSS, and Javascript development on the Mac. The realtime viewing of your coding is awesome. My only issue is that the preview sometimes fouls up, meaning that if you adjust a stylesheet file and then click on a link in the preview that goes to another html page in your folder the stylesheet may or may not update for the page, maybe a caching issue? When this happens I just close the app and open it back up. It loads quick so no major issue there. It would be nice if it had the option to open up to the tabs last opened in previous sessions and if folders would open when highlighted and the space bar is pressed (a common feature in other IDEs). To sum it up….if you are a web designer or coder, this is, in my humble opinion, the best app in the app store.

Down with Xcode. CodeRunner for life.

SOOOOOOOOOOOOO much better than Xcode. Themes are awesome, layout is crispy clean, and it’s fast. I would like to see support for running the terminal in a new window, but other than that it’s as close to perfect as possible. Worth every dollar and more.

A good starting point

I’ve been using NetBeans for web development and this is a much better solution. My machine doesn’t overheat or run super slow with CodeRunner 2 and the auto complete is fantastic. The only thing it’s missing is FTP/SFTP support, without that the only benefit CodeRunner 2 has over TextWrangler is that it has the code completion, but for a senior level developer code completion is trivial compared to the file transfer support. Add that and this will be my primary web development tool in a heartbeat! Very nice to finally have access to development tool for C#, Lua, Java etc. Can’t wait to play with those!

Nice app for PHP development

It's the easiest way to get PHP development and debugging working on a Mac. I did find one bug when I migrated from one Mac to another - CodeRunner would crash at startup. I had to delete the app and reinstall it from the App Store.

Deserves 5 stars

After trying Code::Blocks (crashing like a crazy), Nertbeans (must instal java), Xcode (only good for projects not single files) and even Code::Blocks running in a Virtual Machine, I foud this little gem that not only is a great C++ editor but has included a compiler a can run your C++ ( or other languages as well) code on the same application. Great purchase!

Works as advertised.

I have been using this for 4 years. Works absolutely perfectly. Not sure about all the reviews who have had problems because I have had none. Runs my Python code natively and super fast. Prefer the working environment to TextWrangler and Notepad++ but is similar.

Great Tool for testing and learning

I have used CodeRunner 2 over the past year as a tool for learning new programming languages. The interface is simple, has a large amount of languages that you can use, and is a great value for the cost. Appreciate easy to use apps like this. keep up the good work

Can’t Understand

I can’t understand why does it supports html but it doesnt support css, how am i going to design a website then, if someone knows how please respond, thanks.

Fantastic lightweight editor+runner

Developers will always scoff at apps like these (especially ones whose primary notability derives from the Mac App Store—normally a bit sketchy), which make you pay for what you could likely get for free from such popular editors as Sublime, Atom, Notepad++, Vim, etc. But I can whole-heartedly vouch for the legitimacy of Coderunner on all fronts. It is virtually bug-free, has a dead-simple interface, is extremely fast, is delightfully customizable, has excellent syntax highlighting for a good variety of languages, and most importantly, lets you run your programs with the touch of a button, no strings attached. I personally use it for small programs and self-contained bits of code—it serves as an excellent, speedy testing groundy to dump snippets into or to build up sections of a larger project. It is also a fine editor for HTML and Markdown, as it renders it in the output window when you press run. Of course, I’ll tend toward full IDE’s for larger, more interconnected projects, but when it comes to single-file programs, I find it faster and more pleasant than the more popular editors.

Exactly what I needed, works perfectly

I read the reviews, skeptic about what other people were saying, crashes, slow, clunky, but I’m not having any of those issues. Works perfectly fine for me! Also, this text editor has everything I was looking for to program Python, and it’s very user friendly. Great for beginners!

Not exactly everything promised

This is slow and clunky which caused it to crash and I was only able to get it to work once with HTML. The free program worked better. I am not happy with this purchase.

Warm Towel Out of the Dryer Feeling for CodeRunner

I love to write code. Mainly in Python, Swift and C#. But I like to dabble in different languages. I suffered through many IDE’s over the years. I realized that way too much of my time was spent messing about with learning the IDE itself. Too many IDE’s. Not enough time spent coding. I downloaded the free trial program, which was good for 30 days. On day three I decided to buy it on the app store so I could load it on all my Macs. I just love it too much. You can easily theme it. It runs clean and light, with never a crash, despite daily use. The IDE is intuitive enough with autocomplete without being a bother. It’s tight and just what you need. I do wish it would come out in Linux for my students. But having it in Mac is so wonderful. Keep up the good work!

Show invisibles is missing?

The only missing thing I'd love see added.

Crashing on opening

it was working good, but it’s been two month this app is reusing to open, i left messages on their website, but no response, i spent 14 bucks for that.

Best Coding App

This is the best coding App I had ever used

Great app that works very well!

everything i was looking for in an ide. come with a bunch of pre installed language libraries and allows a good amount for configurtion. Also includes the ablity to test the code right from the app. Great for web developers.

Thanks free non-App store version

As for study programming, CodeRunner 2 is good! Thanks for study programming. Also, Thanks for free non-App store version licensing!!! So I have two CodeRunner 2, App store version & non-App store version both. good to buy!!! Thank for study developing study Apple looks so delicious and happy. Have a nice day!

Worked great for 24 hours

Then after the 24 hours, the message “fI you're experiencing issues running code with the App Store version of CodeRunner, please try using the non-App Store version downloadable from this website. It's free for App Store customers, just follow the instructions in the licensing window"
