Ask HN: Hacker Friendly Terminal (Linux/macOS)

I’d look at zsh autosuggestions as a possible starting point. It’s based on your history and suggests previous commands based on what you type, but there’s no reason it couldn’t provide a suggestion “immediately”. https://github.com/zsh-users/zsh-autosuggestions

As others have suggested, use zsh autosuggestions, personally I like to use oh-my-zsh as the framework for adding zsh plugins, but I don't think its required. As for the terminal emulator, iTerm is stellar, but the terminal emulator does not handle things such as autosuggestions, that's all up to the shell.

There are some shells [1] that can do that based off your history. This doesn't answer your question but may provide an alternative.
