After polishing the source code and making sure no sensitive info was left, I've decided to release Golang Cafe open source. Many people have asked me to release the project open source since first I've launched it.
The project has been released under BSD 3 Clause license which allows commercial use as long as it's not using the same brand name/copyright.
