CapabilitiesSizes and regions
Large machines
Machines of 16 vCPU or 32 GiB memory or more are available.
Short answer: 7 of 16 providers offer it fully: Boat, InstaBox, Modal, Runtime, Sandboxer, Tensorlake and boxd. With a catch: Agent 37, Blaxel, Daytona, Morph and Vercel Sandbox. Checked 29 October 2026.
Who offers it
Part of Sizes, regions and hardware, which explains why it matters.
Fully: Boat, boxd, InstaBox, Modal, Runtime, Sandboxer and Tensorlake. With a catch: Agent 37, Blaxel, Daytona, Morph and Vercel Sandbox. Not at all: Cloudflare Sandbox, E2B, Lizard and Sprites.
Note: Only on the $100-a-month plan or above.
The 16-core size needs the $100-a-month plan.
pricing-page “xlarge needs the $100 plan or higher.” Source
The 32 GiB size is the ceiling and some accounts have to email the team to get 8 cores.
docs-confirmed “This is the largest size a single machine may have, 8 vCPU / 32 GiB unless the boxd team raised it for your org.” Source
Note: Only on the $500-a-month plan or above.
The 32-core size needs the $500-a-month Team plan.
docs-confirmed “Team: 2/4 up to 32 vCPUs / 64 GiB” Source
Modal enforces a maximum but does not publish what it is.
docs-confirmed “a maximum is enforced at Function or Sandbox creation time” Source
docs-confirmed “at most 65,536 (64 GiB) on a paid sandbox” Source
Note: Only on the $100-a-month plan or above.
The 16-core size needs the $100-a-month plan.
pricing-page “xlarge needs the $100/month plan or higher.” Source
Note: Only on the $250-a-month plan or above.
The 16-core size needs the $250-a-month Pro plan; prepaid credit stops at 4 cores and 16 GB.
docs-confirmed “16 vCPU, 64 GB RAM, 100 GB root disk” Source
The catch: One page caps every machine at 4 cores, while another prices a 16-core, 32 GB machine on the 2.5x VM type, so the large size is unclear.
Contradiction between the sizing page and the VM page; see notes.
docs-confirmed “4 vCPU is the ceiling on every instance type.” Source
The catch: The standard sizes stop at 16 GB of memory; anything larger is a custom deployment you have to arrange.
pricing-page “Up to 256 GB RAM per sandbox or job” Source
The catch: A normal sandbox stops at 4 cores and 8 GB; larger machines only come attached to graphics cards.
docs-confirmed “Organizations get a maximum sandbox resource limit of 4 vCPUs, 8GB RAM, and 10GB disk.” Source
The catch: The plan allows up to 1024 cores across the account, but the largest single machine is not published.
pricing-page “Up to 1024 vCPU” Source
The catch: Machines above 8 cores and 16 GB need the Enterprise plan; the self-serve plans stop there.
docs-confirmed “You can provision 1 or an even number of vCPUs between 2 and 32 depending on your plan.” Source
Note: The largest machine is 4 cores and 12 GB of memory, so a 16-core or 32 GB machine is not available.
docs-confirmed “Maximum vCPU” Source
Note: The ceiling is 8 cores and 8 GB of memory, so a 32 GB machine cannot be bought.
docs-confirmed “Max vCPUs” Source
Note: The largest machine is 8 cores and 16 GB, so a 32 GB machine is not offered.
docs-confirmed “Sandbox sizes run from Small (2 vCPU / 4 GB) to Large (8 vCPU / 16 GB)” Source
Note: The machine is fixed at 8 cores and up to 16 GB of memory, below the 32 GB mark.
docs-confirmed “up to 8 CPUs and 16GB of RAM for any given run” Source
