Isolated sandboxes where an AI agent can run the code it just wrote without touching anything you care about.
At a glance
| Amazon Bedrock AgentCore | E2B | |
|---|---|---|
| Pricing | EnterpriseConsumption-based AWS pricing across the AgentCore services, billed alongside the rest of your AWS spend. Model inference is billed separately through Bedrock or your chosen provider. | FreemiumHobby is free with $100 one-time usage credits, community support, sessions up to 1 hour, and 20 concurrent sandboxes; no credit card required. Pro is $150/month with customisable sandbox CPU and RAM, sessions up to 24 hours, and 100 concurrent sandboxes, expandable by purchase to 1,100. Enterprise is custom. Compute is billed per second on vCPU, RAM, and storage on top of the plan fee. |

Pros & cons
Amazon Bedrock AgentCore
Pros
- Framework-agnostic — keep LangGraph, CrewAI, or a custom loop
- Managed identity, memory, gateway, and observability primitives
- Evaluations and Harness cover both production monitoring and pre-production testing
- Policy controls give security teams enforceable guardrails
- Inherits AWS compliance and regional footprint
Cons
- Only sensible if you are already committed to AWS
- Consumption pricing across several services is hard to forecast up front
- Component-by-component GA rollout means capability varies by region
- Steeper learning curve than a hosted agent platform
E2B
Pros
- Real isolation for agent-executed code — the correct security posture
- Sub-second sandbox start times
- Free tier with $100 credits is enough for a genuine evaluation
- Concurrency limits are published and purchasable
- Per-second billing means short runs are genuinely cheap
Cons
- The $150 Pro step is steep relative to the free tier
- Compute is billed on top of the plan fee — the plan price is not your bill
- Long-lived idle sandboxes are the standard way teams overspend
- Developer infrastructure — no value without engineering
- You still own the prompt-injection risk; isolation limits blast radius, it does not prevent bad instructions
Which should you choose?
E2B is the lighter-weight option (Freemium), while Amazon Bedrock AgentCore sits higher on the pricing ladder (Enterprise). Amazon Bedrock AgentCore is built around enterprises already running on aws; E2B leans more toward teams shipping code-interpreter or data-analysis agent features. Shortlist the one whose strengths line up with your biggest constraint.
