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 60
  • Agent ergonomics, 75 against 66
  • Security & auth, 87 against 60
  • Transparency & trust, 70 against 49

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

Runloop Devboxes B

Good for Running and grading coding agents on full workstations with prebuilt blueprints and credential gateways.

Ahead on

  • Payments & pricing, 50 against 30
  • Maintenance & community, 83 against 65

Watch for

About twice the per-vCPU price of E2B or Daytona

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.

Runloop Devboxes

Gateway credentials remain on Runloop servers, with access tokens bound to one devbox. Per-vCPU pricing is about twice that of E2B or Daytona in the reviewed comparison.

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

Runloop Devboxes

  1. Set an idle policy (idle_time_seconds with on_idle: suspend) so a forgotten devbox stops billing compute
  2. Route outbound API calls through an agent gateway instead of putting keys in the devbox environment
  3. Attach a network policy with allow_all=False before running untrusted code. Egress is open by default
  4. Restart background services after every resume. Nothing in memory survives
  5. Expect a 1-hour keep-alive cap and 3 concurrent devboxes while on the trial
