WordPress: Who works on the server?

Hey WordPress developers: I am interested to learn about your behaviour when it comes to WP development. Do you have a local development environment where you develop first? Or do you work directly on the server?

Additionally

• If you have, what's you local dev like — XAMP, MAMP, Vagrant …?
• Do you use SSH?
• Do you even use Git — and if how?

Thanks a ton!
