Good day Habrovchane. I would like to make a small review of the IDE online, having a free and paid version, which I began to use due to some problems with
Cloud9IDE . I will not describe the problems, but sometimes the system was completely unavailable for several hours a day, which prompted the search for a replacement. My requirements were not high and therefore I chose
IDE ShiftEdit , which is very actively developing and the cost of an annual ShiftEdit subscription is only 50 USD (or 5 USD per month) and for this money you can add an unlimited number of projects and give access to them with your own to colleagues.

Key features:
- Allows you to edit documents written in the following languages PHP, Ruby, Python, Perl, Java, HTML, CSS and JavaScript;
- Online editing of documents via FTP / SFTP, Dropbox and Google Drive, unfortunately github is not available and for many, when choosing an online IDE, this minus will be critical;
- You can run several projects, but already in the paid version;
- Joint work on projects - you can invite colleagues;
- Ability to import from Dreamweaver projects in the paid version;
- Code completion (not always working correctly);
- Syntax checking on the fly;
- Rolling back changes chronologically with browsing history is also available in the paid version;
- Snippets;
- Search / Replace text;
- And all sorts of chips, like line numbers, auto-close parentheses and tags;
- Support SHH Key authentication;
- Email support in the paid version;
')

I had enough of the functions out of the box for editing client sites via ftp.
Pleasant features were noticed:
- When an IDE update is released, the system remains available and offers to apply updates. At this point, it automatically saves all open documents and reloads them with new IDE features.
- Supports Drag & Drop to upload files.
- There are 2 skins of the Blue and Gray interface.
- Support for those code.
- Ability to select the entire line.
- Highlight the current active row.
- Design Mode allows WYSIWYG editing HTML documents, but I personally did not like this mode.

- Keyboard shortcuts - you can choose the mode VIM or Zen Coding.

Available settings:
From the system settings, I would highlight the most useful for me:
- Ability to enable autosave code.
- Restore open tabs on startup.
- Trim extra spaces when closing.
- Choice between two ACE or Code Mirror editors
- A lot of settings for Java Script, CSS and Coffee Script.
The number of settings is decent and I will not describe everything; those who are interested will be able to see for themselves.

Conclusion
This system is most likely suitable for those who, like me, need to edit several projects at the same time. It allows me to do this via ftp access to client hosting, share projects between the performers and it is quite stable. For all the time of use, the service was unavailable only once, which I cannot say about Cloud9, although there are some goodies and amenities there and, in principle, Cloud9 impressed me more, but this is another story.
