Founder of Fig here. For context, Fig integrates with your existing terminal and shell.

A few things we've found: 1. Developers are understandably opinionated about their terminal/shell setup. It's a matter of personal productivity. 2. We have noticed a general trend of more terminal use happening in IDE, not a standalone terminal. 3. Most terminal "collaboration" happens asynchronously not synchronously (e.g. shared scripts, CLIs, secrets etc as opposed to live terminal sharing) 4. Most of the collaboration happens at the shell level not the terminal level

Given the above, we made the conscious conscious decision not to build our own terminal.

Happy to elaborate more
