- REST API - Every tool available via API. Interactive docs included at
/api/docs - Single container - One
docker run, no Redis, no Postgres, no external services - Multi-arch - Runs on AMD64 and ARM64 (Intel, Apple Silicon, Raspberry Pi)
- Your data stays yours - No telemetry, no tracking, no external calls. Images never leave your machine
Quick Start
docker run -d -p 1349:1349 -v stirling-data:/data stirlingimage/stirling-image:latest
Open http://localhost:1349 in your browser.
Looking for the Lite or CUDA image? Click here.
Lite (~1.5 GB) - all image tools, no AI:
docker run -d -p 1349:1349 -v stirling-data:/data stirlingimage/stirling-image:lite
CUDA (~14 GB) - GPU-accelerated background removal, upscaling, and OCR:
docker run -d -p 1349:1349 --gpus all -v stirling-data:/data stirlingimage/stirling-image:cuda
CUDA needs an NVIDIA GPU and Container Toolkit. Falls back to CPU if no GPU is found. See Docker Tags for benchmarks and Docker Compose examples.
