Open source developers and authors now have a huge number of services that offer free levels, but it can be difficult to find them all to make informed decisions.
This is a list of software (SaaS, PaaS, IaaS, etc.) and other offers that have free levels for developers.
The scope of this list is limited to things that can be useful to infrastructure developers (system administrators, DevOps practices, etc.). We like all the free services, but it would be good to keep it in one topic.
This list is the result of reviews, ideas and work done by more than 1,100 people. Thank you free-for.dev
