Question 1

What is Avenrail?

Accepted Answer

Avenrail is a free desktop app for macOS that gives coding-agent CLIs like Claude Code, Codex, and Cursor a graphical interface. You run several agents side by side, see what each one changed, review and commit their work, and use a built-in terminal — all in one window.

Question 2

Is Avenrail a GUI for Claude Code?

Accepted Answer

Yes. Avenrail runs the Claude Code you already have installed and signed in, and gives it a desktop interface: a readable transcript, a model picker, a review panel for its changes, and a terminal. It works the same way for Codex, Cursor CLI, OpenCode, and the other supported agents.

Question 3

Is Avenrail free?

Accepted Answer

Yes. Avenrail is free to download and use. You keep paying for your agents the way you do today — Avenrail doesn't charge anything on top.

Question 4

Which agents does it work with?

Accepted Answer

Claude Code, Codex, Cursor, Grok Build, OpenCode, Antigravity, Pi, omp, fx, and Hermes Agent. If one is installed and signed in on your computer, Avenrail can run it.

Question 5

Do I need API keys?

Accepted Answer

No. Avenrail uses the sign-in you already have for each agent, so your existing plan and limits apply as they are.

Question 6

How is it different from running an agent in the terminal?

Accepted Answer

The agent is the same; the workspace around it is different. Instead of one terminal window per agent, every session sits in a sidebar with its status, the files it touched are one click away, a review panel lets you commit and open pull requests, and a terminal stays next to the conversation.

Question 7

Can I run several coding agents in parallel?

Accepted Answer

Yes. Start as many sessions as you like and split them side by side. Each agent can work on its own branch, so they don't overwrite each other, and you review and ship each one's changes separately.

Question 8

Where does my code go?

Accepted Answer

Nowhere new. Avenrail runs on your computer and starts each agent there, so your code reaches your agent's provider exactly as it would from your own terminal.

Question 9

Which platforms are supported?

Accepted Answer

macOS, on both Apple Silicon and Intel Macs. Windows and Linux versions are coming soon. Avenrail is still early, so expect some rough edges.

Question 10

How do updates work?

Accepted Answer

Avenrail checks for a new release when it starts and every few hours while it's open. When one is out, an Update button appears in the sidebar. Updates are signed, and Avenrail refuses any package whose signature doesn't match.

Question 11

macOS says it can't verify the developer. What do I do?

Accepted Answer

Avenrail isn't notarized by Apple yet, so the first launch of a downloaded copy needs one confirmation. Open Avenrail from Applications, close the warning, then go to System Settings › Privacy & Security and click Open Anyway. Later launches and in-app updates open directly.
