You do need to do the system admin, have physical space & power - but one box can host all 8 of your VMs. And the dollar cost is low after the 1-time investment. (OK, 1-time every 5 - 8 years...)
You don't need much (external) network bandwidth once setup - a git mirror is cheap, as is start/stop/status for CI jobs.
Cloud virtual seems like a bargain initially, but as you've discovered, in the long run they make money by enticing you with special introductory offers, then eventually raising the costs.

The curl Cirrus CI pages now link[1] to a notice that they're limiting their free CI tier starting next week. The new limit will be "50 compute credits" per month, which seems to buy us about 260 hours of compute time. Unfortunately, curl has been using about 6000 hours of compute time per month lately[2]. At that rate, our free time will be used up on the first day. They have an easy-to-use credit-card entry form for us to buy credits, but it looks to me like that would cost us almost $3500 per month (presumably USD). Another option is to rent one or more virtual servers somewhere and hook them up to Cirrus CI for only $10 per month. To replace our current usage would require at least 8 virtual servers, though, so still several hundred dollars per month. Finally, we could migrate all but the FreeBSD jobs to one of the CI services still offering a reasonable free tier (Azure and GHA). We can almost squeeze in our FreeBSD builds within our the Cirrus CI monthly credits, and I'm not aware of another CI service that offers FreeBSD servers, so that's probably the cheapest way forward. But it probably means more latency and slower build results as we load the other services even more.
