Sandbox pricing that pays for active compute, nothing on standby

Per-second and per-gigabyte rates are roughly the same across the sandbox category. What changes the bill is the architecture. Because Blaxel scales sandboxes to zero the second they are idle and resumes the full memory state in about 25 milliseconds, teams run up to 70 percent more cost-effectively in practice at the same unit rates. The cause is infrastructure designed to scale to zero and resume instantly.

[TECHNICAL DEEP DIVE]

How it works

View the rate table
  • $0 of compute costs on standby

    Idle sandboxes cost no active CPU. The runtime auto-suspends when idle, and suspended time never counts toward compute. You pay only for marginal snapshot storage time.

  • Same unit rates, lower bills

    Up to 70 percent more cost-effective in practice through scale-down and consumption optimization, not discounted list prices.

  • Start free

    Up to $200 in free credits. Spin up your first sandbox in under a second.

  • Scale with quotas

    Grow to 50,000+ concurrent sandboxes and up to 512 TB of volume storage on a tier-based quota system that upgrades automatically as you top up.

Your journey

Traditional sandboxes provision from scratch on every run, stay alive for an hour at most, then lose their state forever. Blaxel inverts that. A Blaxel sandbox runs for any duration, drops to standby at $0 compute when idle, and restores in about 25 milliseconds on the next call - with process state, memory, and filesystem unchanged.

Multiple deployment options

Run Blaxel the way your security and residency requirements demand.

The same runtime, the same 25 millisecond resumes, wherever your workloads need to live.

  • Managed cloud

    The fastest path to production. Fully managed by Blaxel, with tier-based quotas that scale as you grow. Reach 50,000+ concurrent sandboxes.

  • Private networking

    Run on Blaxel's managed cloud offering but interconnect your virtual private cloud through private endpoints, so your data never transits the public internet.

  • Bring-your-own-metal

    The closest option for self-hosted deployments. Deploy bare metal servers in your own VPC, and privately connect them to Blaxel control plane for the sandbox runtime, so data stays on your hardware during execution.

[FAQ]

Frequently Asked Questions

How fast does an agent resume after being idle?
Sandboxes scale to zero after about 5 seconds of inactivity and resume from standby in roughly 25ms, even after weeks of being suspended.
Does my agent keep its memory between runs?
Yes. In-memory filesystem snapshots keep a suspended sandbox ready to resume. For guaranteed long-term persistence, attach a Volume or use Agent Drive, which can retain data for years.
How isolated is each agent?
Every agent runs in its own hardware-isolated microVM with full access to its filesystem, processes, and logs, plus native support for Zero Data Retention.
How long can an agent run?
Sandboxes are built for workloads lasting seconds to hours. For longer background work you can pair them with Batch API, which runs up to 24 hours.
What does it cost to keep an agent on standby?
You stop paying for compute while a sandbox is suspended. You only pay the standby snapshot storage rate to keep it ready for instant resume.
