Who offers it

Part of Billing models, which explains why it matters.

Fully: Boat, Lizard and Sandboxer. Not at all: Agent 37, Blaxel, boxd, Cloudflare Sandbox, Daytona, E2B, InstaBox, Modal, Morph, Runtime, Sprites, Tensorlake and Vercel Sandbox.

  • BoatYes$26 a month for default

    A flat hourly rate per size; the monthly figure assumes 730 hours of running.

    pricing-page “One default sandbox that runs a full month (730 h) costs $26.” Source

  • LizardYes$0.0324/h medium

    Three fixed sizes with a flat hourly price each.

    pricing-page “Sandboxes come in three sizes, priced per hour and billed per second while they run, including idle time” Source

  • SandboxerYes$26.28 a month default

    A flat rate per size inside a monthly plan.

    pricing-page “Pay for running time only: one price per hour for each machine size, metered per second.” Source

  • Agent 37Nometered parts

    Note: The bill is cores plus memory plus disk, so it moves with the shape you choose.

    docs-confirmed “The monthly price is the rate; the wallet is metered per minute” Source

  • BlaxelNoper GB-second

    Note: The price follows the memory you allocate and the seconds it runs.

    inferred “$0.0000115 / GB RAM · second” Source

  • boxdNothree meters

    Note: Cores, memory and disk are metered separately, so there is no single monthly price.

    inferred “Credit-based.” Source

  • Cloudflare SandboxNoper 10 ms

    Note: The bill is a sum of active processor time, memory and disk.

    inferred “Containers are billed for every 10ms that they are actively running” Source

  • DaytonaNometered parts

    Note: The bill is cores plus memory plus disk per second.

    docs-confirmed “Sandboxes are billed for the resources reserved: vCPU, RAM, and disk” Source

  • E2BNoper second parts

    Note: The bill is cores plus memory per second.

    inferred “$0.000014 per vCPU-second” Source

  • InstaBoxNometered parts

    Note: The bill is cores plus memory per second, plus storage.

    docs-confirmed “Runtime is metered by the second, only while a machine is running.” Source

  • MorphNoone rate per unit

    Note: The price is a single rate per unit hour, not a fixed monthly price per machine.

    inferred “standard MCU rate of” Source

  • RuntimeNomeasured parts

    Note: The bill is measured processor time plus reserved memory plus storage.

    docs-confirmed “the same sandbox costs $0.03125 an hour, for memory plus the default CPU floor of 50 millicores” Source

  • SpritesNoactual use

    Note: The bill follows the processor and memory actually used, so it varies with the work.

    inferred “$0.0385 / CPU-hour” Source

  • TensorlakeNometered parts

    Note: The bill is processor time plus memory plus disk plus storage.

    docs-confirmed “Active CPU per core-hour” Source

  • Vercel SandboxNoactive CPU plus memory

    Note: The bill is active processor time plus memory for as long as the sandbox runs.

    inferred “$0.128/hour” Source

Where it decides the choice

The feature

Words used here

  • Active-CPU billingThe processor is charged only while it is working, not while it waits. Cheap for agents that spend most of their time idle.
  • Per-second billingUsage is counted to the second, so a two-minute task costs two minutes. Some providers round up to a minimum first.
  • Included usageA monthly plan fee that comes with the same amount, or a set amount, of usage. You pay the fee even if you use less, and pay extra only above it.
