E2B vs Docker: sandbox costs

Choose E2B for managed execution at $16.56 per 100 compute hours in this configuration; Docker Sandbox runs locally with $0 software fees and separately funded host resources.

Updated 2026-10-29 · 3 sources · Methodology

Dimension	Comparison result	Scope	Evidence
Managed cloud execution	E2B	$16.56 / 100 hours	E2B provides hosted execution at $16.56 for 100 hours; Docker local host costs are separate.¹²
Local execution	Docker Sandbox	$0 software fee	Docker Sandbox runs a local microVM with a $0 software fee; host resources remain user-funded.¹²
Shared local workspace	Docker Sandbox	Local filesystem	Docker explicitly shares the local workspace; E2B uses a remote sandbox filesystem.¹³

Capabilities and serving conditions

Dimension	E2B	Docker Sandbox
Serving and capacity	Hobby sessions end after 1 hour. Pro extends sessions to 24 hours but adds $150/month before compute; the $100 signup credit is one-time.¹	Local software excludes host, power, operations and model inference. A $0 software license is not a $0 total compute cost.²

When each option fits

E2B

E2B moves execution off the local Docker host and provides 20 concurrent Hobby sandboxes; the trade-off is metered cloud compute and a 1-hour session limit.¹

Docker Sandbox

This comparison uses Docker’s local sandbox mode. The sbx CLI also manages Docker cloud sandboxes, whose compute is billed separately.²

Methodology and sources

E2B / Docker Sandbox. Compute uses 100 total runtime hours, 2 vCPU and 4 GiB nominal memory, with 100% active CPU, before credits and monthly platform fees. Storage, egress and creation charges are excluded. Docker’s local software has no metered host price here and is excluded from the cloud compute cost ranking. Runtime allocation, plan-specific concurrency and lifetime are provider conditions, not a common startup-time column. Published timing statements use different events and do not establish a cross-vendor latency ranking.
