Developers and Open Source authors now have a massive amount of services offering free tiers but it can be hard to find them all in order to make informed decisions.
This then is a list of software, SaaS, PaaS, IaaS etc offerings that have free tiers for devs.
The scope of this particular list is limited to things infrastructure developers - System Administrator, DevOps Practitioners etc - are likely to find useful. We love all the free services out there but it would be good to keep it on topic. It's a bit of a grey line at times so this is a bit oppinionate, do not be offended if I do not accept your contribution.
You can help by sending Pull Requests to add more services. Once I have a good set of link in this README file I'll look into a better layout for the information and links, help with that appreciated too.
If you're not inclined to make PRs you can tweet me at @ripienaar
