# Getting Started

## Quick Start

```bash
docker run -d --name SnapOtter -p 1349:1349 -v SnapOtter-data:/data snapotter/snapotter:latest
```

You will be asked to change your password on first login.

::: tip Also on GHCR
```bash
docker run -d --name SnapOtter -p 1349:1349 -v SnapOtter-data:/data ghcr.io/snapotter-hq/snapotter:latest
```

Both registries publish the same image on every release.
:::

::: tip NVIDIA GPU acceleration
Add `--gpus all` for GPU-accelerated background removal, upscaling, OCR, face enhancement, and restoration:

```bash
docker run -d --name SnapOtter -p 1349:1349 --gpus all -v SnapOtter-data:/data snapotter/snapotter:latest
```

Requires the [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html). Falls back to CPU automatically. See [Docker Tags](/guide/docker-tags) for benchmarks.

### Pipelines

Chain tools into multi-step workflows and apply them to one image or a whole batch:

1. Open **Pipelines** in the sidebar.
2. Add steps (any tool, any settings).
3. Run on a single file - or an entire batch at once.
4. Save the pipeline for later reuse.

Pipelines have unlimited steps by default.

### File Library

Every file you process can be saved to your **Files** library. SnapOtter tracks the full version history so you can trace every processing step from the original upload to the final output.

### REST API & API Keys

Every tool is accessible via HTTP:

```bash
curl -X POST http://localhost:1349/api/v1/tools/resize \
  -H "Authorization: Bearer si_<your-api-key>" \
  -F "file=@photo.jpg" \
  -F 'settings={"width":800,"height":600,"fit":"cover"}'
```

Generate API keys under **Settings → API Keys**. See the [REST API reference](/api/rest) for all endpoints, or visit [http://localhost:1349/api/docs](http://localhost:1349/api/docs) for the interactive reference.

### Multi-User & Teams

Enable multiple users with role-based access control:

- **Admin**: full access - manage users, teams, settings, all files/pipelines/API keys
- **User**: use tools, manage own files/pipelines/API keys

Create teams under **Settings → Teams** to group users.

Set `AUTH_ENABLED=true` (or `false` for single-user/self-use without login).
