# Providers — every sandbox provider, one API

Start a sandbox on any live provider with the same API, CLI and console. Pick one, or leave it on auto and Sandbox Router places each run and fails over for you. Integrated provider rows describe what works through Sandbox Router. Cua Spaces describes its own-compute product. Maritime and Superserve show their native hosted services and direct compute rates.

| Provider | Price at M (per hour) | Isolation | Snapshots | Kept after stop | Max session | Max vCPU | Max memory | Max disk | Self-hostable |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| Cloudflare | $0.282 | microVM (Firecracker) | No | Nothing | No limit (stops when idle) | 4 | 12 GiB | 20 GB | No |
| Daytona | $0.199 (estimated) | Container + microVM | Filesystem (memory on VMs) | Disk | No limit (stops when idle) | 4 | 12 GiB | 20 GiB | Yes |
| E2B | $0.198 (estimated) | microVM (Firecracker) | Memory (and fork) | Disk + memory | No limit (VM renewed hourly) | 4 | 12 GiB | 20 GiB | Yes |
| Freestyle | $0.267 | VM (own KVM, bare metal) | Memory (and fork) | Disk + memory (paid plans) | No limit | 4 | 8 GiB | 32 GiB | No |
| Maritime | $0.022 | microVM + VM (Firecracker / QEMU/KVM / AWS EC2) | Memory + disk (and fork) | Nothing (pause keeps state) | 24 h | 16 | 64 GiB | 500 GiB | No |
| TensorLake | ≤ $0.232 | microVM (Cloud Hypervisor) | Memory (and fork) | Disk + memory (named sandboxes) | 24 h (Pro: no limit) | 4 | 12 GiB | 20 GiB | Yes |
| Cua Spaces | Own compute | Container / VM (host-dependent) | By runtime (checkpoints / forks) | By runtime (local persistence) | By location (local / cloud limits) | Your host | Your host | Your storage | Yes |
| Superserve | $0.166 | microVM (Firecracker) | Memory + disk (and fork) | Disk + memory (on pause) | No limit (Developer / Pro) | 16 | 64 GiB | — | Yes |

Price at M: the hourly price for common size M (2 vCPU, 4 GiB) at 100% CPU, priced at the nearest size Sandbox Router creates on each provider, rounded up: 2 vCPU, 6 GiB and 10 GB on Cloudflare, Daytona, E2B and TensorLake, and Freestyle's one VM. Prices come from each provider's pricing page and Sandbox Router's own rate for Cloudflare, checked 6 Nov 2026. On the page, pick another common size (S to XL, 2 GiB per vCPU, or a custom vCPU and memory), how busy the CPU is, and hourly or monthly (730 hours of running). estimated: Daytona's and E2B's shape isn't confirmed. If Sandbox Router boots Daytona's default sandbox, every size gets 1 vCPU · 1 GiB · 3 GiB: $0.067/hr. If Sandbox Router boots E2B's base template, every size gets 2 vCPU · 512 MiB · 10 GiB: $0.109/hr. ≤: TensorLake bills CPU only while busy, so this is the most. Auto doesn't sort by price: it tries providers in your Auto order (console, Settings).

Maritime’s limits describe its native sandbox product, supplied on 10 Nov 2026: up to 16 vCPU, 64 GiB memory and 500 GiB disk, available from Starter.

For the other integrated rows, max vCPU, memory and disk are the largest size Sandbox Router starts on that provider, preset or custom, with the provider plan it needs where that is more than the smallest size's; Daytona's and E2B's are estimates while their shape isn't confirmed. On your own key, the provider's limits for your plan apply. Daytona's defaults fit up to M: L needs Daytona to raise your limits. E2B's Hobby plan fits up to M: L needs E2B Pro and a limit raise. XL (8 vCPU · 16 GiB) is over every provider's limits through Sandbox Router. Freestyle runs every size on its one default VM (4 vCPU, 8 GiB).

Each provider's page shows [ComputeSDK](https://www.computesdk.com/benchmarks/sandboxes)'s burst time-to-interactive score and build time, with the rank ComputeSDK's page for that provider shows for the latest run, and "Failed" where every attempt failed.

Filter by price terms, isolation, snapshots, persistence, session length, GPU and self-hosting, and sort by name or lowest price.

Compare two or three side by side: `https://sandboxrouter.io/providers/compare?p=cloudflare,freestyle`. Each provider has its own page, such as `https://sandboxrouter.io/providers/e2b`.

**Own compute:** [Cua Spaces](/providers/cua-spaces) runs agent desktops on computers or cloud accounts you supply. Its page covers the current SDK, local warm pools, service plans and sources, checked 10 Nov 2026. Cua Cloud/Fleets ended on 18 October 2026.

**Maritime:** [Sandbox pricing](/providers/maritime) comes from Maritime’s provider submission dated 10 Nov 2026: CPU and memory billed per second, disk included while running, and paused disk at $0.08/GB-month. The monthly plan includes usage credit. Agent boxes, desktops, phones and swarms have separate billing.

**Hosted sandboxes:** [Superserve](/providers/superserve) offers Firecracker microVMs, full-state pause, snapshots and forks. Its size-based price covers CPU and memory; retained storage is separate. Developer requires a monthly plan with usage credit; larger sizes need Pro. The standard detail page covers these terms, template sizes, networking and Enterprise BYOC, checked 10 Nov 2026.

**Standby Pool.** Spare capacity Sandbox Router keeps in reserve. You don't pick it: a run lands here only when every provider you use is down or full.
