Vercel Sandbox pricing and limits

• Each sandbox can use a maximum of 8 vCPUs with 2 GB of memory allocated per vCPU
• You cannot use the sudo command. Your code is executed as the vercel-sandbox user
• Sandboxes have a maximum runtime duration of 45 minutes, with a default of 5 minutes. You can configure this using the timeout option of Sandbox.create().
• You can run Node.js or Python runtimes. Review the system specifications.

Vercel tracks sandbox usage by:

• Active CPU: The amount of CPU time your code consumes, measured in milliseconds. Waiting for I/O (e.g. calling AI models, database queries) does not count towards Active CPU.
• Provisioned memory: The memory size of your sandbox instances (in GB), multiplied by the time they are running (measured in hours).
• Network bandwidth: The incoming and outgoing network traffic in and out of your sandbox for tasks such as installing packages and sandbox usage by external traffic through the sandbox listening port.
• Sandbox creations: The number of times you started a sandbox.

If you exceed the above allotment, you can continue using sandboxes under Pro and Enterprise plans based on the following regional pricing:

At any time, based on your plan, you can run up to a maximum number of sandboxes at the same time. You can upgrade if you're on Hobby. For Pro and Enterprise, this limit will only apply during the Beta period.
