The full agentic terminal multiplexer as a native app — panes, agents and embedded web views in one window. The rysh CLI is bundled; you do not need to install it separately.

Rysh runs agents against your own Anthropic API key — nothing is proxied through us. On first launch the app asks for the key and writes it to ~/.config/rysh/rysh.config.yaml. If you already use the CLI, the app picks up that config and your existing sessions.
Drag to Applications, then launch it.
Paste an Anthropic key when prompted.
Point it at a project directory and start a pane.
The app updates itself. New versions are downloaded in the background and installed when you next quit — there is nothing to re-download from this page.
The rysh CLI is the same engine without the desktop shell — it runs over SSH, in a container, or anywhere you already live in a terminal.
brew install rysh-ai/rysh/ryshcurl -fsSL https://rysh.ai/install.sh | shAPT and RPM repositories are set up in the installation docs.
There is no native Windows build. Rysh allocates a real PTY for every pane, and the native Windows path needs a ConPTY implementation we have not shipped yet — a Windows app would install and then fail to open a single pane, so we do not publish one.
Inside WSL2 the Linux build runs unmodified:
wsl --install -d Ubuntu
