Paused costs only storage

A paused or stopped machine bills for its kept files only, not CPU or memory.

Short answer: 14 of 16 providers offer it fully: Agent 37, Blaxel, Boat, Cloudflare Sandbox, Daytona, E2B, InstaBox, Lizard, Morph, Runtime, Sandboxer, Sprites, Tensorlake and Vercel Sandbox. With a catch: boxd. Checked 29 October 2026.

Who offers it

Part of Billing models, which explains why it matters.

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

  • Agent 37Yesdisk only

    docs-confirmed “The disk rate alone: $0.09 per reserved GB per month.” Source

  • BlaxelYesstorage only

    docs-confirmed “You are not charged for memory while a sandbox is in standby mode.” Source

  • BoatYesnothing for 14 days

    After 14 days the disk is deleted unless you saved a snapshot.

    docs-confirmed “A stopped sandbox keeps its disk for free for 14 days.” Source

  • Cloudflare SandboxYesnothing while stopped

    The disk does not survive a stop, so there is nothing to pay for.

  • DaytonaYesdisk only

    docs-confirmed “Billed for reserved disk only. The preserved memory state is not billed.” Source

  • E2BYesnothing while paused

    Separately kept volumes and snapshots are billed on their own.

    docs-confirmed “Paused and killed sandboxes are not billed.” Source

  • InstaBoxYesstorage only

    pricing-page “Pause it, and you just pay for its disk” Source

  • LizardYescompute stops

    Paused storage on a separate volume is billed on its own.

  • MorphYessnapshot only

    docs-confirmed “You only get charged for the snapshot taken” Source

  • RuntimeYesstorage only

    docs-confirmed “A paused sandbox keeps its files and memory for $0.08 per decimal GB per 30-day month.” Source

  • SandboxerYesnothing while stopped

    docs-confirmed “Time while stopped is never counted.” Source

  • SpritesYescompute stops

    Storage for the files you keep is still charged while it sleeps.

    docs-confirmed “Sprites have three states: running (billed), warm (not billed), and cold (not billed).” Source

  • TensorlakeYesstorage only

    docs-confirmed “Consumes no compute; state is preserved for resume under the same sandbox ID.” Source

  • Vercel SandboxYescompute stops

    A saved copy of the disk bills as snapshot storage after it stops.

    docs-confirmed “Stop a sandbox when work is done to end CPU and memory charges.” Source

  • boxdWith a catchpause keeps paying for memory

    The catch: Pausing keeps the memory in place and you keep paying for it; only hibernating or stopping brings the bill down to disk alone.

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.
