Install the Titen CLI on macOS, Linux, WSL, or Windows, or add the SDK with your JavaScript package manager.

macOS, Linux, and WSL

The installer adds Bun when it is missing or older than 1.2, then installs the titen command for your current user. It does not use sudo, start a service, or create a Titen database.

curl -fsSL https://titen.dev/install.sh | bash

To review it first:

curl -fsSL https://titen.dev/install.sh -o install.sh
less install.sh
bash install.sh

Windows

Run this in Windows PowerShell 5.1 or PowerShell 7. The installer does not need Administrator access and does not change your execution policy.

irm https://titen.dev/install.ps1 | iex

To review it first:

irm https://titen.dev/install.ps1 -OutFile install.ps1
Get-Content .\install.ps1
& .\install.ps1

Pin a version

Installers accept latest or one exact stable version. A pin never accepts a range or prerelease by accident.

curl -fsSL https://titen.dev/install.sh | bash -s -- --version 0.3.1

& ([scriptblock]::Create((irm https://titen.dev/install.ps1))) -Version 0.3.1

Both installers finish by running titen --version. Installing the CLI alone does not bootstrap an organization, print an API key, or start a server.

Package managers

The npm package is named titen-memory; the executable is named titen. Bun must be on PATH because the local server uses bun:sqlite.

Use	Bun	npm	pnpm
Global CLI	`bun add -g titen-memory@latest`	`npm i -g titen-memory@latest`	`pnpm add -g titen-memory@latest`
One command	`bunx --bun titen-memory@latest --version`	`npx titen-memory@latest --version`	`pnpm dlx titen-memory@latest --version`
Project SDK	`bun add titen-memory`	`npm i titen-memory`	`pnpm add titen-memory`

Yarn can install the SDK with yarn add titen-memory. Its Node-owned yarn dlx runner cannot execute Titen’s Bun TypeScript CLI, so use bunx --bun for a one-off CLI command instead.

Update or remove

Rerun the installer to update to npm latest, or pass an exact version to move to that release. Remove the package with the manager that installed it:

bun remove -g titen-memory
# npm uninstall -g titen-memory
# pnpm remove -g titen-memory

Removing the package does not delete a Titen database, configuration, backup, or API key. Those files belong to you and remain where you created them.

Start Titen

Create the first organization once, save the printed key, then run the local service:

titen bootstrap --org "My Org"
titen serve

Continue with the Quickstart to check readiness and connect an agent.
