~/git/AUR|dev|whatever/$(git clone) is where mine usually reside.

Like some other ppl here, I clone everything in a git folder under my home directory.

/tmp

Unfortunately I'm still on windows, so [User]/Documents/Projects/

Personal?

~

My homedir is a HUGE MESS.

Work?

~/src///

i.e. ~/src/github/mirantis/docker (not real I don't imagine, just an example)

~/src/bitbucket/INTERNALPROJECTCODE/coolrepo

C:\repos or ~/repos

Personal stuff goes in ~/Projects

Work stuff goes in ~/Work/Code

Same! I also have a separate directory for college assignments and stuff. Gonna set up separate gitconfigs for both soon, so there is a smaller chance of mixing up my credentials

In ~/src Mostly because I'm too lazy to type "source".

Putting one directly under the home directory feels like a psychopathic move, so I stay by XDG and put them under a subdirectory of xdg-documents

~/projs

I like ~/w or ~/p options

$HOME/Code///

I use ghq to manage cloning to get this desired structure

~/Sources for stuff I'm only building from sources and no immediate intention to contribute to

~/Projects for stuff I'm involved in, with a following structure:

Projects
 - Personal
 - - Art
 - - Music
 - - Code
 - - - Ideas
 - - - In progress
 - - - Deployed
 - - - Scripts
 - - - Abandoned
 - [Company name]
 - - [Project name]
 - Interviews
 - - [Company name]

The last part grouping project by companies has worked great for me, especially with freelance and outsource work. Sorting personal projects into types and stages feels like a mistake, as every time I have to navigate it, I can't help but think of limitations of hierarchical file systems, as some of them are multiple types simultaneously, and also moving projects between stages feels dumb.

~/Prototypes on pretty much all machines I own, from desktop, laptop, server, tablets, ebook readers, RPis, XR headset, video projector, etc.

~/Documents/projects/<YYYY>-<MM>-<DD>_<name>

~/repos

~/source

~/gits

Documentation is usually a doc folder inside the repo or just a README.md for small projects.
