The Best AI Sandbox Alternatives
CreateOS Sandbox is an isolated, benchmarked runtime billed per second, with no egress fees, pause that stops vCPU billing with your state preserved, and a published cost and margin. Here is how it compares, on pricing verified June 2026.
Side-by-Side Comparisons
Each comparison uses rates verified June 2026 and links to a full head-to-head breakdown.
CreateOS Sandbox vs AWS Lambda MicroVMs
AWS's serverless Firecracker micro-VM service for running user and AI-generated code, generally available since June 2026.
CreateOS Sandbox vs E2B
An open-source runtime for running AI-generated code in isolated sandboxes.
CreateOS Sandbox vs Daytona
A pay-as-you-go runtime for AI sandboxes with fast spin-up.
CreateOS Sandbox vs Modal
A serverless compute platform with a sandbox SKU and a strong GPU catalog.
CreateOS Sandbox vs Vercel Sandbox
A sandbox tied to the Vercel deploy platform.
CreateOS Sandbox vs Runloop
A devbox runtime aimed at long-running agent sessions.
CreateOS Sandbox vs Cloudflare
Container compute on Cloudflare's global edge network.
CreateOS Sandbox vs Perplexity Sandbox (SPACE)
SPACE is the Firecracker-based runtime behind Perplexity Computer; developers reach it as a Python and bash sandbox tool inside the Agent API, with a standalone Sandbox API on the roadmap.
Common Questions
What is the best AI sandbox?
It depends on your workload, but CreateOS Sandbox stands out on transparent pricing (published cost and margin), no egress fees, and pause with your state preserved, which stops vCPU billing.
Which AI sandbox is cheapest?
On headline per-token rate, providers vary. CreateOS Sandbox bills $0.03616363 per vCPU-hour and $0.01159025 per GiB-hour, and adds no egress fees and pause that stops vCPU billing with state kept. Each comparison shows the verified rates.
What is the best E2B alternative?
CreateOS Sandbox is the closest like-for-like alternative: $0.03616363 per vCPU-hour and $0.01159025 per GiB-hour against E2B's $0.0504 and $0.0162 (verified June 2026), with published cost and margin, no egress fees, no Enterprise minimum, and pause that stops vCPU billing with your state preserved. Daytona, Modal, Runloop, Cloudflare, and AWS Lambda MicroVMs are the other alternatives compared on this page.
Is there a self-hosted or open source alternative to E2B?
E2B itself ships a mature open-source SDK. If the requirement is running the whole sandbox inside your own boundary, CreateOS Sandbox can be self-hosted end to end: run the control plane yourself and bring your own object storage, in your VPC or on-prem, so code and snapshots never leave your network.
What is the best Daytona alternative?
CreateOS Sandbox pause stops vCPU billing where Daytona's stop still bills disk, and there are no egress fees. The CreateOS vs Daytona comparison below has the June 2026 rates side by side, and the vs E2B page covers the same dimensions if you are weighing Daytona against E2B.
Is there a CreateOS Sandbox alternative to AWS Lambda MicroVMs?
Yes. Both run user and AI-generated code in Firecracker micro-VMs that suspend when idle and resume warm. CreateOS Sandbox adds fork of a diverged paused state into N branches, private sandbox-to-sandbox overlay networks for multi-node clusters, no egress fees, and full self-host of the control plane and storage. AWS counters with general availability today, its existing compliance programs, and larger MicroVMs up to 16 vCPU and 32 GB.
How current are these prices?
All competitor rates were verified in June 2026 and are dated on each comparison. Sandbox pricing changes often, so we re-verify before publishing.
