Sandbox pricing

A sandbox is billed for the CPU and memory of its size, for the time it runs.

Rates

Resource	Rate
CPU	$0.015 per vCPU per hour
Memory	$0.008 per GB per hour
Snapshot storage	$0.25 per GB per month

Price per size

Size	vCPU	Memory	Disk	Per hour
Micro (`sbx.micro`)	1	1 GB	2 GB	$0.023
Small (`sbx.small`)	2	2 GB	4 GB	$0.046
Medium (`sbx.medium`)	2	4 GB	8 GB	$0.062

Which sizes you can create depends on your plan.

How usage is measured

By the second. There is no minimum charge and no rounding up to a minute or an hour.
From ready to stopped. Billing starts when the sandbox is ready, not when you request it, and stops when it is paused or destroyed.
Paused sandboxes are not billed for CPU or memory. Pausing releases the compute and keeps the sandbox’s volume.
By size, not by load. A sandbox is billed for the size it was created with, whether it is busy or idle. Destroy or pause sandboxes you are not using.

Included with your plan

Each month your plan covers an amount of sandbox usage. The rates above apply beyond it.

Plan	CPU included	Memory included
Hacker	5 vCPU-hours	10 GB-hours
Developer	20 vCPU-hours	40 GB-hours
Team	20 vCPU-hours	40 GB-hours

Sandboxes are not available on the Free plan.

Labels

You can label a sandbox when you create it, for example with the agent, run or customer it belongs to. Send metadata with up to 20 keys:

curl -X POST https://core.brimble.io/v1/sandboxes \
  -H "x-brimble-key: $BRIMBLE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"template": "node-22", "metadata": {"agent": "researcher", "run": "run-42"}}'

Labels are returned with the sandbox and attached to its costs in the cost export, so you can see what each agent, run or customer cost.
