I literally use this site 6/7 days a week. Its a great online repl tool. Not sure what I would do with out it. Love it.

Pros:

So many languages available now, store code snippets, work through bugs, I use this as much as my text editor.

Cons:

lately it's been a bit sticky when I first log in and try to type the first few characters, This is a new issue.

This is possibly the most convenient IDE I have used for transporting code across multiple computers, as it is entirely cloud based. More features are being added every day, and they are almost always useful.

However, as aforementioned, the speed/memory is very low. In my experience, a simple loop can only process about 1000 times per second with 2 or 3 lines of code. In Visual Studio, on the other hand, the same code can process 10000-20000 iterations per second. If you are writing any resource intensive or massively looping programs, I would recommend against it in that instance. For any more simple programs, however, the simplicity and mobility of this website makes it my favorite IDE.

Pros:

Incredibly easy to work from multiple locations

One IDE for many common and obscure languages

Still in development, so only improving.

Cons:

Processing speed/memory low.

Thanks for your feedback, the speed might lower a little bit if you have huge files and you're running out of memory, that's why we created Hacker Plan so you can still code in the cloud with double of the speed and the memory.

I'm a computer programming teacher, and repl works fantastically for myself and my classrooms. I'm able to evaluate my students' work online, offer feedback, and set up automatic code validation testing. People may also write their own programs separate from classrooms, and save them to Repl's cloud based server. Since the website is still under development, you may encounter the occasional glitch; but by notifying the repl team, they'll usually have that fixed in a matter of hours. Overall, I strongly recommend using this website, especially since the team continues to improve it and make it better.

Pros:

Free online cloud-based IDE for many programming languages. Great for classrooms!

Cons:

The occasional glitch (usually fixed within hours), as website is continually made better.

We used this with my daughters (middle school and elementary) for a school project, and it was night and day difference from previous coding experiences. For a generation that has grown up on Google docs, the experience feels so obvious and natural. We got it hooked up to github very easily as well, so they could get some level of version control without having to do all the incantations that developers all blindly accept. Auto-complete, etc are top notch. And the fact that there's an immediate publishable URL makes the feedback loop feel very fast.
