Compute Lite runs the NocoDB sandboxes for scripts, AI code execution and the App Builder on your own servers, as one Docker container.

Compute Lite runs NocoDB sandboxes on your own servers instead of [E2B](https://e2b.dev/). Sandboxes run [scripts](/docs/workflows/scripts), the [Run script](/docs/workflows/nodes/action-nodes/run-script) workflow step, code in [NocoAI](/docs/product/noco-ai) chat, and the App Builder. Compute Lite runs as one Docker container. It needs no KVM and no cloud account.

### How it works

```
 NocoDB ──HTTP (API key)──▶ Compute Lite :8430 ──▶ Docker ──▶ sandbox containers
   │                                                              ▲
   └──HTTP/WebSocket──────▶ Compute Lite :8431 (port proxy) ───────┘
```

* **Port 8430** is the API. NocoDB creates sandboxes and runs code through it, with an API key.
* **Port 8431** is the proxy to the sandboxes. NocoDB reaches each sandbox at `<port>-<sandbox-id>.sandbox.example.com`. The proxy reads this host name to find the sandbox, so a Service name alone is not enough. A wildcard DNS name, such as `*.sandbox.example.com`, must resolve to Compute Lite from NocoDB. It can be an internal name.

Only NocoDB connects to Compute Lite. Browsers never do.

| ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| License | The Compute Lite add-on, on a self-hosted Scale or Enterprise license. Without the add-on, NocoDB ignores Compute Lite. See [Purchase a license](/docs/self-hosting/purchase-license). |
| NocoDB  | The Enterprise Docker image (not the npm package). Helm is not required.                                                                                                               |
| Host    | Linux, amd64 or arm64, Docker 24+. On Kubernetes, privileged pods.                                                                                                                     |
| Memory  | 1 GB, plus 1 GB per chat or script sandbox and 4 GB per App Builder sandbox that run at once.                                                                                          |
| Disk    | 30 GB free. The sandbox images take about 20 GB.                                                                                                                                       |
| Network | Access to Docker Hub, or a [private registry](/docs/self-hosting/installation/compute-lite/configure#private-registry-or-air-gapped).                                                  |

### Security

* Sandboxes are containers, not virtual machines. Treat the Compute Lite host as a host that runs untrusted code.
* Sandboxes cannot reach private networks (`10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`, cloud metadata) or each other. They can reach the internet. This applies in the default embedded mode, not in [host mode](/docs/self-hosting/installation/compute-lite/configure#host-mode).
