Ranked in these QuestionsQuestion Ranking
Pro More modern than vim
Pro Actively developed and supported
Pro Text selection mechanism
Kakoune works on selections, which are oriented, inclusive range of characters, selections have an anchor and a cursor character. Most commands move both of them, except when extending selection where the anchor character stays fixed and the cursor one moves around.
Pro Will be familiar to vim users
Kakoune first started as a rewrite from scratch of vim, but then ended up being another text editor altogether. So it's inspired in a lot of ways from vim.
Pro Very expressive
Kakoune provides a very expressive set of commands, including various objects selection (paragraph, blocks, words), alignment support, conditional selection filtering...
This set of command is expressive enough to implement all the provided auto indentation logic.
Pro Good UNIX citizen
It follows the UNIX philosophy by doing one thing well (text editing) and interfaces nicely with other CLI tools.
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 Small community
Con Lack of options/ability to customize
The ability to customize Kakoune are currently quite limited. Everything is hard coded, and there is a lack of options to choose from.
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.
