# Pay-as-you-go agent sandboxes: prices at 2 vCPU / 4 GB (Nov 2026) Billed for what you use: no plan fee and no credit to buy first. 13 providers: one busy 1-hour session at 2 vCPU / 4 GB costs ≥ $0.0288 (Koyeb) to $0.317 (Runloop). 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.
