Render Sandboxes now available in beta

Now in public beta, use Render Sandboxes to spin up isolated, ephemeral compute environments for executing untrusted code, such as agent-generated apps and scripts.

Create and manage sandboxes programmatically using the Render CLI or the TypeScript and Python SDKs.

Each sandbox provides:

Isolated runtime: Run commands and manage files in a contained environment with its own filesystem.
Configurable compute: Choose from four compute plans with up to 8 CPU and 16 GB of RAM.
Indefinite execution: Run sandboxes for as long as you need. Configure separate timeouts for automatic suspension and termination, or disable both to run indefinitely.
Network controls: Restrict outbound traffic to specific HTTPS destinations, or block it entirely.
Reusable snapshots: Capture filesystem state or running processes, then restore that state in new sandboxes.

To create your first sandbox and execute a command:

Install the latest version of the Render CLI.
Spin up a sandbox with:
bash
```
# Create a sandbox and wait until it's running.
render sandboxes create --timeout=300 --wait
```
Copy your new sandbox's ID from the command's output.

Replace sbx-abc123 with your sandbox's ID in the following commands:

bash

# Execute a basic echo command.
render sandboxes exec sbx-abc123 -- echo hello from Render

# Terminate the sandbox when finished.
render sandboxes stop sbx-abc123 --confirm
