core

Code is still here and usable for c9: https://github.com/c9/core I bet it's hella outdated and full of security issues now though.

An older version of version of the Cloud9 core SDK is open source at https://github.com/c9/core. Instructions for downloading an older offline version of the CS50 IDE are available at https://cs50.readthedocs.io/ide/offline. Unfortunately the new versions are not open source at the time of this writing.

Sadly I second that. Also I had problem with their "DDoS protection" which detected false-positive DDoS attack. I got instance suspended after 6 days after payment for next month without any refund. They noticed "weird" traffic to my instance where I had installed Cloud9 [0][1] and I assume built-in terminal was flooding instance with TCP-SYN packets when I was using it. I am glad that I haven't left anything inside, because I lost access to this instance and storage. Before that, I thought such protection rather stops instances not drops them with mounted SSD disks to do not impose an impact on other instances.

Cloud9 Core available on github. They never replied regarding a onprem license[0]. [0]: https://github.com/c9/core/blob/master/LICENSE-COMMERCIAL-US...

It's never lead to problems for me. However, some of my coworkers decided not to use c9 due to latency (which has never bothered me for some reason.) I use the ssh-workspace feature and do my work in an EC2 instance. I've also been playing around with running a local c9 build (https://github.com/c9/core). Not sure that their license would make this viable for commercial work, but ofc there's no latency / connection requirement if you're running it locally. Off-topic, you could even run c9 locally in a Chromebook if you were using Crouton -- and without having to install another desktop environment. I do most of my work on a desktop, but if I ever get together a mobile development environment this may be what I do.

It is really easy as[0]: git clone git://github.com/c9/core.git c9sdk cd c9sdk scripts/install-sdk.sh to get c9 installed. But the license[1] :( There is a cloud9 v2[2] alterantive but ide.c9.io just more polished.

Hosted here: https://github.com/c9/core/ Notable tech: Emmet (snippets, HTML autocomplete), Engine.IO (web-sockets), MsgPack (message serialization), RuSHA (browser-based SHA1), Tern (code analysis, AST etc), Acorn (JS code analysis, faster than Tern)

I use c9.io, and also a self-hosted version (https://github.com/c9/core) occasionally. Using even the free c9 service, connecting to your own server via SSH, you can create a fantastic collaborative development environment. Although I do most of my development locally, cloud IDEs are perfect for the remote pair-programming use-case - they're far better than screen-sharing.

Big c9sdk[0] fan here. I don't have high hope, because last time I tried atom on my i7 it ran like a dog. [0]: https://github.com/c9/core

It used to be messy but now it's largely just: git clone git://github.com/c9/core.git c9sdk cd c9sdk scripts/install-sdk.sh https://github.com/c9/core

It is most definitely open source it is just not unconditional, maybe that will change now. https://github.com/c9/core

This doesn't make sense? The editor is open source. You can install it on your computer right now. They even provide instructions on how to do it. https://github.com/c9/core They can implement it without buying the company. Even if the license doesn't allow it, the license for ACE surely does and ACE is the meat of the editor. https://github.com/ajaxorg/ace Maybe they want the team because they want to move the product in a certain direction? I don't know.

I wonder if anyone can comment on how this compares to cloud 9 IDE? (https://github.com/c9/core/)

Of this 330409 lines of Javascript code, the majority (223414 lines) of it is stuff in the node_modules subdirectory, which probably is what you mean by dependencies...? E.g, there is one file in there https://github.com/c9/core/blob/master/node_modules/ace/lib/... that contains 54209 lines of code.
