- **Image editor:** Layer-based editor with brushes, shapes, adjustments, filters, curves, and keyboard shortcuts. Runs in your browser, processes on your hardware
- **Local AI:** Remove backgrounds, upscale images, restore and colorize old photos, erase objects, blur faces, enhance faces, extract text (OCR), expand canvas, fix transparency. All on your hardware, no internet required

- **Single container:** One `docker run`, no Redis, no Postgres, no external services
- **Multi-arch:** Runs on AMD64 and ARM64 (Intel, Apple Silicon, Raspberry Pi)
- **Privacy first:** Your images never leave your network. SnapOtter asks once whether you'd like to share anonymous product analytics (which tools are used, errors encountered, never file data). Change anytime in Settings, or set `ANALYTICS_ENABLED=false` to disable completely

## Quick Start

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

<details>
<summary><sub>Have an NVIDIA GPU? Click here for GPU acceleration.</sub></summary>
<br>

Add `--gpus all` for GPU-accelerated background removal, upscaling, and OCR:

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

> Requires an NVIDIA GPU and [Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html). Falls back to CPU if no GPU is found. See [Docker Tags](https://docs.snapotter.com/guide/docker-tags) for benchmarks and Docker Compose examples.
