In November 2022, after I had been keeping track and adding names to this slide for a few years already, we could boast about curl having run on 89 different operating systems and only one year later we celebrated having reached 100 operating systems.

This time I am back with another update and I here is the official list of the 110 operating systems that have run curl.

I don’t think curl is unique in having reached this many operating systems, but I think it is a rare thing and I think it is even rarer that we actually have tracked all these names down to have them mentioned – and counted.

For several of these cases, no patches or improvements were ever sent back to the curl project and we don’t know how much or little work that was required to make them happen.

The exact definition of “operating system” in this context is vague but separate Linux distributions do not count as another operating system.

There are probably more systems to include. Please tell me if you have run curl on something not currently mentioned.
