GA (April 2026) container-backed sandboxes that give Workers-based agents a persistent isolated computer — exec, code interpreters, PTY terminals, backup/restore — on Cloudflare's edge.
Pricing: Active-CPU pricing: $0.00002 per vCPU-second (billed only for CPU actually used). Requires the Workers Paid plan ($5/mo minimum)
Manual — signup needs a human (card, verification, or sales).
Cloudflare account is free but Containers/Sandboxes require the Workers Paid plan ($5/mo, card required), so an agent cannot self-provision from zero. API tokens for wrangler deploys are self-serve once the paid account exists.
