Multitui creates single-purpose native macOS apps for any terminal app, with optional sandbox. It uses the built-in macOS sandbox-exec along with log monitoring to give you an easy UI to manage rules, see what's being blocked, and add rules as you observe files that need to be allowed.
Does this seem useful? Does it need network sandboxing too?
Also, it's on Product Hunt today, so an upvote would be appreciated!
