imgforge

imgforge is a fast, secure image proxy and transformation server written in Rust. Built with Rust and libvips, it delivers imgproxy-compatible URL semantics with an async-first architecture and optional, pluggable caching backends.

Why choose imgforge

Production-ready from day one – Health checks, structured logging, and Prometheus metrics make imgforge easy to drop into modern platforms.
Container-native – Ship the provided multi-stage Docker image anywhere, or extend it with your own watermark assets and presets.
High-fidelity transforms – Resize, crop, format-convert, blur, sharpen, watermark, and more—powered by libvips for incredible performance.
Defense in depth – Signed URLs, bearer tokens, per-request safeguards, and global rate limiting protect your origins from abuse.

Feature highlights

On-the-fly resizing, cropping, format conversion, watermarking, and other libvips-backed transforms.
Signed URL enforcement with optional bearer authentication and rate limiting.
Memory, disk, and hybrid caches powered by Foyer for efficient content reuse.
Prometheus metrics, structured tracing, and health endpoints suitable for production observability.

Get started in minutes

Generate development-only values with OpenSSL:

openssl rand -hex 32

docker pull ghcr.io/imgforger/imgforge:latest
docker run --rm -p 3000:3000 \
  -e IMGFORGE_KEY=<generated_key> \
  -e IMGFORGE_SALT=<generated_salt> \
  ghcr.io/imgforger/imgforge:latest

Then follow the Quick Start guide to sign URLs and try your first transformation. Prefer bare-metal builds or CI integrations? See Installation for native toolchain instructions.
