# MicroVM agent sandboxes: prices at 2 vCPU / 4 GB (Nov 2026)

Each sandbox is a Firecracker, Cloud Hypervisor or Kata microVM. 11 providers: one busy 1-hour session at 2 vCPU / 4 GB costs ≥ $0.0162 (Lizard) to ≥ $0.341 (Vercel Sandbox).

1 h busy: all CPU billed. 1 h at 10% CPU: lower only where idle CPU isn't billed. Fleet month: 50 × 8 h × 22 days, busy, on the lowest plan that runs 50 at once (its fee, less the usage it includes). At once and Starts are on the terms priced. Fixed sizes use the smallest size that fits. "≥" means a billing term is not published. Method: https://roost.guide/methodology/
