Go: Image-Processing Microservice

Imaginary is a fun little package that can be Dockerized and deployed next to the rest of your services to offload image-processing:

Fast HTTP microservice written in Go for high-level image processing backed by bimg and libvips. imaginary can be used as private or public HTTP service for massive image processing with first-class support for Docker & Heroku. It’s almost dependency-free and only uses net/http native package without additional abstractions for better performance.
