# Sandbox pricing and limits URL: https://docs.munito.ai/sandboxes/pricing A sandbox pays for each second, for its CPU and its memory. It pays for the higher of its floor and its real use. - The ceiling is the vCPUs and the memory that the sandbox sees. - The floor is the smallest share that the sandbox pays for: a quarter of the ceiling. ## Sizes [#sizes] | Preset | Ceiling | Floor | Idle, per hour | Busy at the ceiling, per hour | | --------- | ------------- | ------------------ | -------------- | ----------------------------- | | `small` | 1 vCPU, 1 GiB | 0.25 vCPU, 256 MiB | $0.0072 | $0.0288 | | `default` | 2 vCPU, 4 GiB | 0.5 vCPU, 1 GiB | $0.0162 | $0.0648 | | `large` | 4 vCPU, 8 GiB | 1 vCPU, 2 GiB | $0.0324 | $0.1296 | | Resource | Price | | ----------- | ------------------------------------------------ | | CPU | $0.0252 per vCPU-hour | | Memory | $0.0036 per GiB-hour | | Saved state | $0.0001 per GiB-hour, about $0.073 per GiB-month | - A create without `size` gets the `default` size. - For another size, set `vcpus` and `memory_mib` in place of `size`. - A preset starts in less than one second. A custom size takes some seconds. - For a larger root disk, set `disk_gib`, for example `{"size": "large", "disk_gib": 40}`. - To pay for the ceiling all the time, set `"reserved": true`. The floor is then the ceiling. - The saved state of a [paused sandbox](https://docs.munito.ai/sandboxes/persistence) pays the storage price. Data that two saved states share, such as a fork and its parent, counts one time. - The Sandboxes page of the console shows the vCPU-hours, the GiB-hours and the spend of the month. ## Free time and credits [#free-time-and-credits] - Each organization gets 25 free hours of a `default` sandbox at full use, one time. That is the first $1.62 of sandbox usage, so an idle sandbox runs longer for free. - The free time needs no credits. - After the free time, a sandbox needs credits. Buy credits on the Billing page of the [console](https://console.munito.ai/billing). - A sandbox runs after its request ends. Thus, the API checks the credits before it starts or extends a sandbox. | Code | When the API answers 402 | | ------------------ | ------------------------------------------------------------------------------------------- | | `credits_low` | The credits pay for less than one hour of the largest size, 16 vCPUs and 32 GiB at full use | | `credits_used_up` | The credits of your organization are used up | | `credits_required` | Your organization has no credits | - The API answers these codes to a create and to a new timeout, after the free time is used. - When the free time and the credits are used up, your running sandboxes stop. Their `end_reason` is `credits`. - With automatic top-up on, the sandboxes continue while the top-up can add credits. ## Limits [#limits] | Limit | Value | | ------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | vCPUs | 1 to 16 | | Memory | 512 to 32,768 MiB, in steps of 256 MiB. At least 512 MiB for each vCPU | | Disk | 10 to 100 GiB, set with `disk_gib`. The default is 10 | | Life of a sandbox | 10 to 86,400 seconds. The default is 3,600, one hour | | Time of a command | 1 to 1,800 seconds. The default is 60 | | Output of a command | 1 MiB for each stream when you wait for the result. `truncated` is true when the API cuts the output | | File | 100 MiB | | Environment | 100 variables. A value is 32 KiB or less | | Metadata | 16 keys. A key is 64 characters or less, and a value 512 or less | | Running sandboxes | 100 at once for each organization. Above this limit, a create gets 429 `sandbox_limit_reached`. Talk to an engineer for more | | Creates | No limit. API requests from one IP address are limited to 8,000 a minute | | Public ports | 16 for each sandbox | | SSH keys | 16 for each sandbox | | Signed URL | 60 seconds to 7 days. The default is one hour | ### Network [#network] - A sandbox has outbound internet access. - A sandbox cannot reach your other sandboxes or private addresses. It cannot send mail over SMTP. - For a sandbox with no network, set `"internet": false`. - Inbound connections come only through [ports and SSH](https://docs.munito.ai/sandboxes/ports-and-ssh), also with `"internet": false`. ## A weekend of agents [#a-weekend-of-agents] Agents wait for their models most of the time, so the price of an idle sandbox sets the bill. This table gives the price of 60 sandboxes with 2 vCPUs, 4 GiB and a 10 GiB disk, idle from Friday 18:00 to Monday 09:00 (63 hours). It uses the lowest published usage price of each provider on 2026-10-28, with no plan fee, free tier or credit. | Provider | The weekend | Multiple | | ------------------------------------------------------------------- | ----------- | -------- | | Munito | $61 | 1x | | [boat](https://docs.boat.dev/pricing) | $68 | 1.1x | | [Tensorlake](https://www.tensorlake.ai/pricing) | $140 | 2.3x | | [Cloudflare](https://developers.cloudflare.com/containers/pricing/) | $214 | 3.5x | | [Modal](https://modal.com/pricing) | $225 | 3.7x | | [Railway](https://railway.com/pricing) | $263 | 4.3x | | [Vercel](https://vercel.com/docs/vercel-sandbox/pricing) | $321 | 5.2x | | [Freestyle](https://www.freestyle.sh/pricing) | $503 | 8.2x | | [E2B](https://e2b.dev/pricing) | $626 | 10.2x | | [Daytona](https://www.daytona.io/pricing) | $630 | 10.3x | | [Blaxel](https://blaxel.ai/pricing) | $632 | 10.3x | | [Runloop](https://www.runloop.ai/pricing) | $1,210 | 19.8x | - Munito: an idle sandbox pays its floor, 0.5 vCPU and 1 GiB. - Tensorlake: the rates of the Pro plan. - Cloudflare: a container with 2 vCPUs needs 6 GiB of memory or more. - Modal: the row requests 0.25 core and 1 GiB, the floor of a Munito sandbox. - Railway: the row prices 1 GiB of memory in use, the memory floor of a Munito sandbox. - Blaxel: the row prices an active sandbox. A sandbox in standby pays only for its snapshot.
