github actions themselves can be self hosted, its quite nice actually to be able to keep your same patterns as cloud hosted actions and with one line change to the yaml have it running on your own hardware. I do this for actions that take 6-7 hours so I am not burning through the 3000 minutes that come free with my account.
i love this and its something i had always wanted to try. I am actually kind of ticket off at chatgpt as i asked it about 6 months ago how something like this work and it told me it physically wasnt possible. maybe i need to improve my prompting.
