CreateOS Sandbox vs YepCode Run
YepCode Run is the simpler tool when an agent only needs to run a JavaScript or Python function with packages and get output back. CreateOS Sandbox is the better tool when the agent needs a whole Linux machine: a shell, more memory, long sessions and an inbound URL.

Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where YepCode Run has the edge.
A full Linux OS with a shell, not only a language runtime, with devbox:1 carrying Python, Node.js, Go, Rust and Docker.
Up to 16 GB of memory on Enterprise, against 300 MB on Starter and 600 MB on Growth.
No execution time cap, where YepCode stops at 30 seconds, 1 hour or 12 hours by plan.
Documented isolation (Firecracker micro-VM) and opt-in inbound HTTPS.
Where YepCode Run is strong
YepCode Run is the simplest way to run a snippet with any npm or PyPI package: send code, get output, with secrets, scheduling, logs, an MCP server and no-code connectors for n8n, Zapier and Make built in. Its JS and Python SDKs are MIT-licensed.
Which to Pick
Pick CreateOS Sandbox if
- The agent needs shell access and a full OS.
- Jobs need more than 600 MB of RAM or run longer than 12 hours.
- You need to serve a port from inside the sandbox.
Pick YepCode Run if
- Your agent runs short JS or Python functions with third-party packages.
- You want automations wired into n8n, Zapier or Make.
- You need schedules, secrets and logs without managing containers.
Head-to-Head Comparison
Every dimension side by side, checked on 17 October 2026 against each vendor's own docs and pricing pages. "Not published" means we could not find it on the vendor's pages, not that the feature is missing.
| Dimension | CreateOS Sandbox | YepCode Run |
|---|---|---|
| Built for | Sandboxes created by API for agent and untrusted code | Running agent- or user-written JS and Python snippets and automations |
| Isolation | Firecracker micro-VM with its own guest kernel | Not published beyond 'isolated sandboxes' (vendor blog) |
| Ephemeral per-run environments | Yes: create a sandbox per run by API and destroy it after | Yes: ephemeral local disk per execution (5 MB to 5 GB by plan) |
| Pause and resume | Yes: pause saves disk, memory and CPU state; vCPU stops billing, memory and storage still bill | Not published |
| Outbound network | Open with no rules; deny-by-default once any host, IP, CIDR or wildcard rule exists, enforced on the host outside the VM | Not published |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour | Per second of execution in Yeps; Developer free with 50K Yeps |
| Run untrusted code | Yes: each sandbox is its own micro-VM, with host-enforced outbound rules and inbound closed by default | Yes, as JS or Python in language runtimes; 300 MB (Starter) or 600 MB (Growth) RAM |
Common Questions
How long can a YepCode execution run?
YepCode caps execution at 30 seconds on Developer, 1 hour on Starter and 12 hours on Growth, with Enterprise custom. A CreateOS sandbox has no lifetime cap and runs until you destroy it, pause it, or an idle auto-pause you set kicks in.
Can I run a shell command in YepCode Run?
YepCode sandboxes are JavaScript and Python language runtimes without shell or root access. CreateOS sandboxes are full Linux micro-VMs where you can exec any command, open a shell over an API tunnel or SSH, and run managed processes.
How much memory does a YepCode sandbox get?
Self-serve YepCode sandboxes get 300 MB on Starter and 600 MB on Growth, with Enterprise customisable. CreateOS shapes range from 1 vCPU / 1 GB on Free to 8 vCPU / 16 GB on Enterprise.
