Sandboxer vs AWS Bedrock AgentCore (Code Interpreter / Runtime)

Amazon Bedrock AgentCore offers Runtime, which gives each session its own microVM for hosting agents, and a Code Interpreter for running Python, JavaScript or TypeScript in a sandbox. It is tied into IAM, S3 and other AWS services and bills active CPU and memory per second. Sandboxer is a general Ubuntu VM with root, Docker, SSH and memory-preserving stop/resume. Pick AgentCore if your stack is already on AWS and you want managed agent hosting; pick Sandboxer for a full machine per agent.

At a glance

Sandboxer and AWS Bedrock AgentCore (Code Interpreter / Runtime) compared
Capability	Sandboxer	AWS Bedrock AgentCore (Code Interpreter / Runtime)
Isolation	microVM Cloud Hypervisor, its own kernel	microVM per session (Runtime); containerized environment (Code Interpreter) Runtime: dedicated microVM per session, memory sanitized on termination. Code Interpreter docs describe a containerized environment.
Full Linux with root	Ubuntu 24.04, sudo, systemd
Docker inside	Preinstalled
Nested virtualization (/dev/kvm)
Pause and resume with memory	Running processes come back	A stopped session's microVM is terminated; with optional session storage the filesystem at the mount path persists across stop/resume, but memory and processes do not.
Fork a sandbox	Copy-on-write disk copy that boots fresh
HTTPS URL per port	Private with a token, or public
Longest session	No limit on paid plans Auto-stop is up to 30 days or off	Runtime: 8 h per microVM lifecycle (14 d on Instances); Code Interpreter: 15 min default, extendable to 8 h Runtime idle timeout defaults to 15 minutes.
Billing	Per second, flat rate per size Stopped sandboxes are free	per second on active CPU + memory, 1-second minimum Code Interpreter memory charged on peak per second; no CPU charge during I/O wait.
GPUs
Self-host or open source
Regions	US East (Virginia) and EU Central (Finland)	Runtime microVMs in 22 AWS regions Code Interpreter listed as built-in tool in the same regions.

Price for one 4 vCPU, 8 GB machine

Sandboxer

$0.036/hour

Flat per-second rate for the default size

AWS Bedrock AgentCore (Code Interpreter / Runtime)

$0.43/hour

AgentCore Code Interpreter (and Runtime v1) rates: 4 vCPU × $0.0895/h + 8 GB × $0.00945/h = $0.3580 + $0.0756 = $0.4336 per fully busy hour. Billed only for active consumption, so idle time costs less.

Where AWS Bedrock AgentCore (Code Interpreter / Runtime) is strong

Per-session microVM isolation on Runtime, with memory sanitized after the session ends.
Consumption billing per second with no CPU charge during I/O wait.
Native integration with IAM, S3, CloudTrail and CloudWatch for enterprise governance.

Where Sandboxer differs

AgentCore Code Interpreter is a code-execution tool with fixed runtimes (Python, JavaScript, TypeScript) and shell/AWS CLI; Sandboxer is a general Ubuntu 24.04 VM.
Stopped AgentCore sessions lose memory and processes (filesystem can persist with session storage); Sandboxer resumes running processes.
AgentCore ties you to AWS accounts, IAM and supported regions; Sandboxer is used through its own API, CLI and SDKs.

Pick AWS Bedrock AgentCore (Code Interpreter / Runtime) if

You are already on AWS and want agent hosting, identity and observability from the same provider.
You want billing only for active CPU and memory rather than for a running machine.
You need many AWS regions, including GovCloud.

Pick Sandboxer if

You want a sandbox that stops with memory and disk saved and resumes with processes running, with stopped sandboxes costing nothing.
You want Docker, systemd, nested KVM, SSH and coding agents (Claude Code, Codex and others) already installed, with HTTPS URLs for any port, without assembling it yourself.
You want a per-second-billed Ubuntu 24.04 VM driven by a REST API, CLI, MCP server or TypeScript/Python SDK.
