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 is list of software (SaaS, PaaS, IaaS, etc.) and other offerings
that have free tiers for developers.

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 opinionated; 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 links in this README file, I’ll look into a better layout
for the information and links (help with that is appreciated too).

NOTE: This list is only for as-a-Service offerings, not for self
hosted software.
