Install
Download the desktop app
Section titled “Download the desktop app”Agentissimo ships as a native desktop app for macOS (Apple silicon and Intel), requiring macOS 11 (Big Sur) or later. Download the latest release from agentissimo.ai or build it locally.
On first launch, macOS Gatekeeper may warn “unidentified developer”:
Right-click Agentissimo.app → Open → confirm.
Subsequent launches open normally.
Install your agent CLIs
Section titled “Install your agent CLIs”Agentissimo drives the agent CLIs already on your machine — it does not bundle
them. Install the ones you plan to use and make sure each is on your PATH:
| Agent | CLI binary |
|---|---|
| Claude Code | claude |
| Codex | codex |
| Cursor | cursor-agent |
| Copilot | copilot |
| Pi | pi |
A missing CLI shows a clear error naming the binary it tried to run. See Add a driver for setup details.
