Self-hosted image optimization service like Cloudinary, but you own the server.
Core Features
- Supports AVIF, WebP, JPEG XL for superior compression
- One Docker container, easy deployment
- Real-time image fetching, resizing, cropping, caching
- Full self-hosting, data privacy, no API limits
- Customizable parameters for quality, size, format
What It Can't Do
- •If building from source, run `composer install` inside container first; default port is 8080; cache is ephemeral—consider mounting a persistent volume for production.
Use Cases
- Speed up website images for better performance
- Batch resize and compress product images for e-commerce
- Adapt images for different devices and screen sizes
- Replace expensive SaaS image optimization with free self-hosted solution
Detailed Introduction
Flyimg is a Dockerized application that allows you to build your own Cloudinary-like image optimization service. It fetches images from any URL, then resizes, crops, compresses, caches, and serves them in modern formats like AVIF, WebP, and MozJPEG. With one Docker container, you get a complete image processing pipeline. It also supports JPEG XL via ImageMagick. The service is fully self-hosted, giving you full control over your data and no API rate limits. Ideal for developers who want to improve website performance without relying on third-party services.
