I've started a couple of small free open source software projects and am working on the technical infrastructure that supports communication, project planning, source code hosting, etc for these projects.
I'm a developer (not a system administrator) and would like to spend my time on programming, rather than on setting up these systems on my own webserver.
I could use proprietary software (like google groups and slack) but would rather use free open source software.
My question is: Is there any organization that provides hosting for the technical infrastructure for supporting open source projects, and where the software that they host is itself open source?
I'm looking for a place where a whole package of technical infrastructure could be hosted, including communication, project planning, source code hosting, bug tracking, etc.
I am ready to pay a small amount (max 5 euro/month) if necessary and if multiple projects are supported
Grateful for help and with kind regards, Tord
