## Which one, for what

### Amazon Bedrock AgentCore Code Interpreter (BB)

Good for: A team already on AWS that wants agent code to run under IAM, inside a VPC and beside S3 data, for sessions up to eight hours.

Ahead on:
- Reliability, 85 against 48
- Schema & documentation, 81 against 66
- Agent ergonomics, 75 against 60
- Security & auth, 87 against 61
- Payments & pricing, 30 against 20
- Maintenance & community, 65 against 45
- Transparency & trust, 70 against 58

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No pause, resume or snapshot. Session files are removed when the session ends, and persistence needs a customer-owned S3 Files or EFS mount inside a VPC

### Deno Sandbox (D)

Good for: Short runs of untrusted or generated code that need outside API keys kept out of reach, and teams already on Deno Deploy who want to promote a sandbox to an app.

Watch for: Beta since 3 February 2026. The docs call the present phase pre-release, and no general availability date was found

## Verdicts

**Amazon Bedrock AgentCore Code Interpreter.** Each session runs in its own microVM with 2 vCPU, 8 GB and a 10 GB disk for up to eight hours, and IAM can scope access to one interpreter. Sessions cannot be paused or resumed, and an AWS account with IAM set-up is needed before a first call.

**Deno Sandbox.** Secrets stay outside the microVM and are substituted only on outbound requests to approved hosts, and an allowlist limits egress. The service is still in beta, sandboxes need the $20 Pro plan, lifetime is capped at 30 minutes, and no sandbox operation appears in the published OpenAPI document.

## Before you call either

### Amazon Bedrock AgentCore Code Interpreter

1. Start a session with `StartCodeInterpreterSession`, then pass its id in the `x-amzn-code-interpreter-session-id` header on every `InvokeCodeInterpreter` call
2. Set `sessionTimeoutSeconds` when starting. The default is 900 seconds and the maximum is eight hours, and the session ends itself at the timeout
3. Stop sessions when done. Billing runs per second while code is busy, and a session left open counts against the 1,000 concurrent-session quota
4. Use `startCommandExecution`, `getTask` and `stopTask` for work longer than the 15-minute synchronous request limit
5. Retry `ThrottlingException` (429) and `InternalServerException` (500) with exponential backoff, and treat `ServiceQuotaExceededException`, returned as HTTP 402, as a quota to raise

### Deno Sandbox

1. Set `DENO_DEPLOY_TOKEN` to an organisation token (prefix `ddo_`) from Settings in console.deno.com. The organisation must be on Pro or above
2. Pass `allowNet` on every `Sandbox.create()`. The Security page says outbound access is unrestricted when it is omitted
3. Pass credentials through `secrets` with a `hosts` list, not `env`, so code in the VM sees only a placeholder
4. The default timeout ends the VM when the client disconnects. Pass a duration such as `"10m"` and reconnect with `Sandbox.connect({ id })`, up to 30 minutes
5. Create volumes in `ord` and start the sandbox in `ord`. A volume mounts only in its own region
6. `exposeHttp` URLs are public with no authentication. Treat the random subdomain as a secret
