What products do you wish you could self-host?

This hasn't been asked in a while, and I really loved reading the last discussion so I'm hoping to kick it off again and see what has changed!

What I'd like to know is:

- What specific products do you wish you could host on your own infrastructure, but the product does not offer such a deployment method

- Do you or would you use the product without being able to self-host? I.E. In its current state

- Do you think your employer, if any, holds the same opinions?
