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 32
  • Schema & documentation, 81 against 75
  • Agent ergonomics, 75 against 66
  • Security & auth, 87 against 64
  • Maintenance & community, 65 against 26

Also in its favour

  • Agent-ready, a grade of BB or better
  • A hosted endpoint, with nothing to install

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

SPACE C

Best for Teams that want E2B-style microVM sandboxes on their own Linux and Kubernetes hosts, with egress and credential control outside the guest.

Ahead on

  • Payments & pricing, 60 against 30

Also in its favour

  • Open source

Watch for

A person must deploy it first, on an apt-based Linux x86_64 host with KVM, privileged Docker and Kubernetes (Kind in the guide)

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.

SPACE

Once deployed, SPACE's native API has a public OpenAPI 3.1 contract, stable error codes with a retryable flag and 24-hour idempotency keys, and egress and credential controls sit outside the VM. A person must first deploy it on a Linux x86_64 host with KVM and Kubernetes. Version 0.8.0 has no tagged release, changelog or public container images.

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

SPACE

  1. Ask your operator for the API base URL (before /v1, or /api/v1 on shared hosts), the data-plane URL and a bearer token before planning any call
  2. Poll the returned operation until it succeeds and the sandbox is running before creating a command. A 202 response is not readiness
  3. Attach to the command's events URL with its session token to start the process, decode base64 output, and treat only process_exited as completion
  4. Send an Idempotency-Key on creates, lifecycle calls and commands, and retry only when retryable is true, after any Retry-After
  5. Save output as it arrives. Reconnecting with Last-Event-ID returns resync_required, not the missed output
