Comparison
Nix Agents vs Ghostty: an agent workspace or a terminal
These two are not alternatives, and a comparison page that pretended otherwise would be wasting your time. Ghostty replaces the window your shell draws in; Nix Agents is what you reach for when the work you hand to agents outgrows one window.
What Ghostty is
Ghostty is an open-source terminal emulator built by Mitchell Hashimoto and contributors. It renders on the GPU, feels native on the platform it runs on, and does the thing a terminal emulator should do: stay out of the way while you type into a shell.
If your question is "which terminal emulator should I run on macOS or Linux", Ghostty is a serious answer — fast, well made, actively developed.
What Nix Agents is, next to that
Nix Agents is an agent development environment. It does not draw its own text grid — it hosts real terminals (on Windows, actual PTY sessions) and puts structure around them:
- One git worktree per agent session, so two agents never edit the same checkout.
- A diff per worktree, and a merge queue, so work is reviewed before it lands.
- Several agent CLIs — Claude Code, Codex, Gemini CLI and others — side by side on one board.
- Loop and Swarm modes for re-running a task until it passes, or running several at once.
Which one to pick
Pick Ghostty when you want a better terminal: fast, native, and you drive it yourself.
Pick Nix Agents when the bottleneck is no longer the terminal — three agents in three worktrees, three branches and a merge order to keep straight. That bookkeeping is what the workspace takes over.
One platform note, stated plainly: Ghostty’s own site lists macOS and Linux, and Nix Agents ships for Windows today (x64 and native ARM64), with macOS and Linux as build targets rather than downloads. On Windows the overlap between the two questions is currently zero.
Questions
- Does Nix Agents replace my terminal emulator?
- No. It hosts a real terminal per session, but it is not a general-purpose terminal emulator — you would still keep Ghostty, WezTerm or Windows Terminal for your own shell work.
- Is Ghostty available for Windows?
- Ghostty’s own site lists macOS and Linux. Nix Agents is the Windows-native side of this comparison — real PTY terminals on Windows are the reason the project exists.
- Can I use both?
- Yes, and most people do. The terminal emulator is where you work by hand; the workspace is where the agents you handed tasks to work, each in its own worktree.
