Celesto AI's Celesto CI is trending on GitHub Marketplace: it runs GitHub Actions jobs on fresh Linux microVMs claiming 90% lower per-minute cost than GitHub-hosted runners on matching hardware.
- Usage: drop-in replacement — just change runs-on: ubuntu-latest to runs-on: celesto.
- Pricing: a 2 vCPU / 8 GB runner costs $0.00067/min vs GitHub's $0.006/min; six sizes from 1 to 8 vCPU; $5 trial credit, no card required.
- Mechanics: each job boots a fresh Ubuntu 24.04 x64 microVM that is cleaned up afterwards; Docker, Buildx and Compose preinstalled; supports actions/cache with up to 25 GiB cache per repo on paid plans.
- Traction: +14 installs (+12.2%) in 7 days, 129 total, ranked #459 of 1,420 tracked GitHub Marketplace listings (up 17 spots).
