I made a UI for this to run terminal apps, like claude and codex: https://multitui.com

I’m impressed really neat work! Why did you opt for closed source?

edit: I don’t have a problem with closed source, but when software is expected to be accountable for my security I get a little paranoid, so was curious about the safety and guarantees here. The UX and everything else looks great

Yeah, that’s understandable. Many open source macOS-only apps seem to get abandoned, so I’m trying to build something sustainable.

It uses only 3 dependencies that are very well known and widely used, so supply chain risk is minimal. That leaves me, the developer, as the main point of trust.

I like this! I built something similar for sandboxing CLI agents, and in the repo have a collection of minimal profiles for sandbox-exec to use - https://agent-safehouse.dev/

Codex already uses sandbox-exec on macOS :)

Yeah, they all do sometimes, but the agent decides what to allow and they can choose to not use it. This gives the user full control of the sandbox and you can run the agent in yolo mode.

Which terminal do you embed?

SwiftTerm, for not. I may switch to ghostty when their library is ready for embedding.

have you find a way to make claude emit the OSC hyperlink escapes when using SwiftTerm?

No, I run a separate URL detection to make links clickable. However, SwiftTerm just added link detection a few days ago and I haven’t had time to look into theirs yet.

Wow, this looks very nice.
