# Getting Started

::: tip Try before installing
Explore the full UI at [demo.snapotter.com](https://demo.snapotter.com) -- no signup or install required.
:::

## 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 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.
:::

::: details 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.

## Docker Compose

```yaml
services:
  SnapOtter:
    image: snapotter/snapotter:latest  # or ghcr.io/snapotter-hq/snapotter:latest
    ports:
      - "1349:1349"
    volumes:
      - SnapOtter-data:/data
    environment:

See [Configuration](/guide/configuration) for all environment variables.

## Build from Source

**Prerequisites:** Node.js 22+, pnpm 9+, Docker (for Postgres + Redis), Python 3.10+ (for AI features), Git.

```bash
git clone https://github.com/snapotter-hq/SnapOtter.git
cd SnapOtter
docker compose -f docker-compose.dev.yml up -d   # start Postgres + Redis
pnpm install
pnpm dev
```

- Backend: [http://localhost:13490](http://localhost:13490)

## What You Can Do

### File Processing (157 Tools)

| Modality | Count | Example Tools |
|----------|-------|---------------|
| **Image** | 64 | Resize, Crop, Compress, Convert, Remove Background, Upscale, OCR, Watermark, Collage, Colorize, GIF Tools |
| **Video** | 29 | Trim, Crop, Compress, Convert, Merge, Extract Audio, Auto Subtitles, Video to GIF, Resize, Stabilize |
| **Audio** | 17 | Trim, Merge, Convert, Normalize, Noise Reduction, Transcribe, Pitch Shift, Fade, Ringtone Maker |
| **PDF / Document** | 37 | Merge, Split, Compress, OCR, Watermark, Redact, Word to PDF, Excel to PDF, Rotate, Protect, Repair |
| **Data** | 10 | CSV to JSON, JSON to XML, Merge CSVs, Split CSV, Create ZIP, Extract ZIP, Chart Maker, YAML/JSON |

### 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/image/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).
