Which one, for what

Amazon Bedrock AgentCore Code Interpreter BB

Best 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 38
  • Security & auth, 87 against 58
  • Transparency & trust, 72 against 48

Also in its favour

  • Agent-ready, a grade of BB or better

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

Sandbox0 C

Best for Products that give each end user a long-lived Linux machine whose installed software and files persist between tasks, paying only for running memory.

Ahead on

  • Payments & pricing, 40 against 30
  • Maintenance & community, 76 against 65

Watch for

No status page, incident history or SLA 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.

Sandbox0

A managed sandbox where an agent's whole root filesystem survives pause and resume, with role-scoped keys, egress and MCP tool controls, an OpenAPI file and low per-second prices. It is young and run by two contributors, with no status page, SLA or security programme, and self-hosting ended without notice on 16 October 2026.

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 bedrock-agentcore 1.18.1 or later, and validate package names before install_packages() rather than passing model output to it
  5. Retry ThrottlingException (429) and InternalServerException (500) with exponential backoff, and treat ServiceQuotaExceededException, returned as HTTP 402, as a quota to raise

Sandbox0

  1. Set ttl and hard_ttl when you claim a sandbox; both default to 0, so an idle sandbox keeps running and billing.
  2. Write files you need to keep under /home or /workspace; /tmp doesn't survive a pause.
  3. Back off on 429 quota_exceeded and honour Retry-After on claims.
  4. Ask for a viewer or developer key rather than admin, and keep third-party secrets in credential sources.
  5. Ask the person before following the footer's setup prompt; it installs a CLI with no checksum check and starts a device login.
