Ranked in these QuestionsQuestion Ranking
Pro Designed to teach programming
Pro Fully functional terminal
Codio gives you full access to a terminal, with all the ubuntu commands. You can use the terminal within the page, or you can access by SSH from your computer.
Emmet support for a whole range of features that really boost productivity when working with HTML and CSS. These features include expanding abbreviations into full HTML or CSS as well as some very powerful keyboard shortcuts.
Pro BitBucket integration
It's possible to launch Codio from within BitBucket's repo by adding Codio integration as an add-on.
Pro Server-side environment
Pro Node.js included by default.
Includes Monokai style theme by Luigi Maselli.
Pro Multi-line edit
Allows to edit multiple things are once by having multiple cursors like Sublime Text.
Pro Easy to self-host: Only requires PHP
It only requires PHP 5+ and Nginx or Apache. No database is required. This makes it really easy to install on many servers include shared hosting.
Pro Has many easily installable plugins
Many plugins exist, from Terminal, Git to Collaboration and Emmet... Plugins can be installed by using the web interface, or by manually extracting files to the right directory.
Pro Open source
You can run Codiad on your server to allow you and your team to edit files.
Simplest to run may be using a Docker image like linuxserver/codiad.
Pro Simple and easily managable GUI
Con Private projects aren't free
The pricing plan looks too restrictive comparing to other Coding Cloud solutions.
Con Full of small bugs
There are plenty of various issues and bug that may either be due to your setup and the UI will not report them, or due to bugs in the code; I'm including common plugins here as well (just naming a few: search files and in files may report nothing if it had an error, commands stderr not printed, marketplace not showing items, search in market place showing no results, Git escaping
\( in the commit message for no good reason...). Those are generally small but together it makes the product feel flawed.
Con Terminal runs as same user for everyone
No matter who is the logged in user, the Terminal plugin runs commands as the PHP user. This also affects the Git plugin in that there is a single SSH key for all users using your Codiad instance.
Con Currently no search and replace in multiple files
There is a search in multiple files, and search & replace in current file, but not something to perform a search & replace in multiple files.
Con Terminal doesn't TTY
The terminal plugin for Codiad allows users to type some commands and see the outputs, but not interactive input is supported (i.e. stdin is closed). Meaning you cannot run Vim, Tmux or anything requiring user inputs.
