Initial idea is based on the list available at https://github.com/ligurio/Continuous-Integration-services/blob/master/continuous-integration-services-list.md.
It contains only services that provide a sensible amount of features for open source projects or non-profit organisations. I've also added several tools I used or tested with a minimal up and running configuration.
To summarise the review factors for this document:
- open source tools
- suitable for nodeJS application development
