Claude Code, Codex and opencode

Three agents.
One window.

Viby runs the real coding agents on your own plans, with every diff, terminal and preview beside the chat.

Download Viby See it work

Free · Windows 10 and 11 · macOS on Apple Silicon (preview)

01 / 04

Open a folder and ask.

Type what you need. Viby starts the agent you picked and shows its work as it happens: files read, edits made, commands run.

02 / 04

Read every change before you keep it.

Edits land in Changes as a diff beside the chat. Files, a terminal, git and a browser open in the same panel.

03 / 04

Hand the chat to another agent.

Pick Codex or opencode in the composer. The next answer comes from them, with the whole conversation.

04 / 04

Decide how much it may do.

Each engine has its own permission modes. Viby writes your pick into that engine's real settings.

The agents you know. A window that keeps up.

The same agents, inside your apps.

Viby finds Excel, Word, Power BI and Blender on your computer and gives every engine the tools to work in them.

Questions.

Do I need my own API keys?
No. Free models work without a key. For Claude or ChatGPT models, sign in with the account you already have.
Does Viby replace Claude Code or Codex?
No, it runs them. Viby starts the real CLIs, so your plan and settings keep working.
Do I need a Viby account?
Yes, a free one. You sign in once in your browser, with GitHub, Google or an email code.
Which systems does it run on?
Windows 10 and 11, 64-bit. macOS on Apple Silicon is an early preview. Linux is coming.
Windows says “Windows protected your PC”. Is that OK?
Yes, it’s expected. Viby is new and its installer isn’t signed with a paid Microsoft certificate yet, so SmartScreen doesn’t recognise it. Click More info, then Run anyway. If your browser says the file isn’t commonly downloaded, choose Keep.
macOS won’t open Viby. What do I do?
The Mac preview isn’t notarized by Apple yet. Move Viby to Applications and open it once. Then go to System Settings › Privacy & Security, click Open Anyway next to Viby and confirm. You only do this once.
