Install SnapOtter with Docker in one command. Includes Docker Compose setup, building from source, and a full feature overview.

Getting Started

::: tip Try before installing Explore the full UI at demo.snapotter.com - no signup or install required. :::

Quick Start

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:

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

Requires the NVIDIA Container Toolkit. Falls back to CPU automatically. See Docker Tags for benchmarks. :::

::: details Also on GHCR

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. :::

Build from Source

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

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

What You Can Do

File Processing (240 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

Files	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.

Saving is explicit: results you save to the library are kept until you delete them, while results you process and leave unsaved are cleared automatically after 72 hours (configurable via FILE_MAX_AGE_HOURS).

REST API & API Keys

Every tool is accessible via HTTP:

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 for all endpoints, or visit 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).
