Install nteract

macOS (Apple silicon or Intel), Windows, and Linux. The app bundles everything: the notebook, the runt CLI, and the runtimed daemon, kept up to date automatically.

curl -fsSL https://sh.nteract.io | bash

Installs the app (the AppImage on Linux; the signed bundle in ~/Applications on macOS) plus runt, runtimed, and nteract-mcp, links the commands into ~/.local/bin, and sets up the per-user daemon service (systemd on Linux, launchd on macOS). Everything is per-user — no root, no system package manager. Re-run the same command to upgrade.

Stable is the default everywhere above. The nightly channel installs side-by-side with channel-suffixed commands (runt-nightly, nteract-nightly), so you can run both. Agents have their own setup — see nteract for agents.
