Steffen Deusch @steffend.me · 11/09/2026@peterullrich.com For the firecracker runners, do you plan to make those open source? I like self hosting runners, but I don't feel good using them on public repos if the jobs are not isolated. So a way to run KVM based ephemeral runners for each job would be awesome for non-hosted ones too #pushin 131
