# Mosaic Stack Quickstart
Get the Mosaic CLI installed, complete first-run setup, connect to a gateway, and launch an agent session. This page covers the supported installed-CLI path with the default local storage tier.
> **Scope:** This is an end-user installation route. It does not authorize PostgreSQL setup, production deployment, or starting Gateway/Web directly from a source checkout. Use the [administrator guide](../../ADMIN-GUIDE/README.md) for deployment and the [developer guide](../../DEVELOPER-GUIDE/README.md) for contributor setup.
## Requirements
- Node.js 20 or newer.
- npm, for the global Mosaic CLI installation.
- At least one supported agent runtime:
- [Claude Code](https://docs.anthropic.com/en/docs/claude-code)
- [Codex](https://github.com/openai/codex)
- [OpenCode](https://opencode.ai)
- [Pi](https://pi.dev)
- Credentials for the runtime or model provider you plan to use.
## 1. Install Mosaic
The stable installer installs the Mosaic framework and the `mosaic` CLI, then launches the setup wizard by default:
```bash
curl -fsSL https://mosaicstack.dev/install.sh | bash
```
If your security policy requires reviewing the script before execution, download it first and inspect it. The installer also supports the direct repository URL:
```bash
curl -fsSL https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh -o /tmp/mosaic-install.sh
less /tmp/mosaic-install.sh
bash /tmp/mosaic-install.sh
```
To install without automatically launching the wizard:
```bash
bash /tmp/mosaic-install.sh --no-auto-launch
```
The installer places framework files under `~/.config/mosaic/` and installs the CLI under the configured npm global prefix, `~/.npm-global/` by default. Ensure that prefix is on your `PATH` if your shell cannot find `mosaic`.
## 2. Complete first-run setup
If the installer skipped the wizard, run it manually:
```bash
mosaic wizard
```
The wizard guides framework setup and gateway installation. It can collect your agent identity, preferences, provider configuration, and gateway administrator details interactively.
For a separately installed or existing gateway, skip local gateway installation and use its URL in the login step below.
## 3. Verify and sign in
For a gateway installed on this machine, check its health and setup state:
```bash
mosaic gateway status
mosaic gateway verify
```
Sign in without putting your password in shell history or process listings:
```bash
mosaic gateway login
```
The command prompts for the gateway URL, email, and password as needed. Do not pass passwords with `--password`.
For a remote gateway, provide its URL explicitly:
```bash
mosaic gateway login --gateway https://gateway.example.com
```
## 4. Launch Mosaic
Open the interactive terminal interface:
```bash
mosaic tui
```
The TUI defaults to `http://localhost:14242` and can prompt for login if no valid session is saved. To connect it to another gateway:
```bash
mosaic tui --gateway https://gateway.example.com
```
You can also launch a supported runtime through Mosaic:
```bash
mosaic pi
mosaic claude
mosaic codex
mosaic opencode
```
Use the launcher matching the runtime you installed and authenticated.
## 5. Inspect configuration and health
These commands are safe diagnostics and do not change the product requirements or active task ledger:
```bash
mosaic config show
mosaic doctor
mosaic gateway logs
```
If the gateway is unhealthy, run `mosaic gateway status` and `mosaic gateway logs` before attempting a reinstall. If your session expires, run `mosaic gateway login` again.
## Storage and deployment boundary
The default local gateway tier uses embedded PGlite and does not require an external PostgreSQL or Valkey service. This quickstart intentionally does not configure `DATABASE_URL`, PostgreSQL, pgvector, or a federated deployment.
For standalone or federated storage, deployment topology, secrets, SSO, backups, or recovery, stop here and use the [administrator guide](../../ADMIN-GUIDE/README.md). For work from a repository checkout, keep `DATABASE_URL` unset and follow the [developer guide](../../DEVELOPER-GUIDE/README.md); do not use root `pnpm dev` as a local PGlite route while the current dotenv safety hold remains active.
