Archal with CreateOS Sandbox
Use Archal with CreateOS Sandbox when you test agents that act on GitHub, Slack, Stripe or Linear: Archal provides stateful, resettable copies of those APIs, and CreateOS Sandbox runs the agent code. Archal does not run agent code itself, so it pairs with a compute sandbox.
Archal's page says paid continuation is not yet available while its safety rollout remains disabled, so usage beyond the free credit may be limited.

What CreateOS Sandbox Adds
What CreateOS Sandbox brings to this matchup, with a plain note on where Archal has the edge.
Runs the agent under test in a Firecracker micro-VM with its own guest kernel, a job Archal leaves to a compute sandbox.
Egress rules can confine the agent to the hosts a test needs, so a misrouted call does not reach a live account.
Fork a paused sandbox to replay the same agent state against several reset scenarios.
Where Archal is strong
It removes the hardest part of agent integration testing: realistic, stateful, resettable copies of 20+ SaaS APIs that an agent can write to without touching real accounts.
Which to Pick
Pick CreateOS Sandbox if
- You need an isolated place to run the agent under test.
- Agent code must be confined to approved outbound hosts.
- You want to pause and fork agent runs for repeatable tests.
Pick Archal if
- Your agent writes to GitHub, Slack, Stripe, Linear or Jira and you need safe test targets.
- CI needs third-party API state reset to a baseline on every run.
- You want to avoid test accounts and rate limits.
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 | Archal |
|---|---|---|
| Isolation | Firecracker micro-VM with its own guest kernel | Not published; sandbox per run, branch or CI job; simulations, not live services |
| Pause and resume | Pause saves disk, memory and CPU state; vCPU stops billing, memory and storage still bill | State persists within a sandbox; reset restores every environment to baseline |
| Outbound network default | Open with no rules; deny-by-default once any host, IP, CIDR or wildcard rule exists, enforced on the host outside the VM | Environment traffic routed to Archal-managed implementations; general egress not applicable |
| Inbound access | Closed by default; opt-in public HTTPS URL | REST and MCP endpoints per environment |
| Largest size | 8 vCPU / 16 GB on Enterprise; 8 vCPU / 8 GB on Pro | Not applicable (no general compute) |
| Session length | No cap; idle auto-pause 60 s to 24 h, off by default | Time-bounded; duration not published |
| Billing | Per second: $0.03616363 per vCPU-hour, $0.01159025 per GiB-hour, storage $0.0001584 per GB-hour; no egress fees, 50 GiB bandwidth budget per sandbox | $0.10 per minute per environment, prorated by the second |
| SDKs and interfaces | TypeScript, Go, Python, Rust, C#, Java SDKs (all but TypeScript pre-1.0), CLI, MCP, REST | REST, MCP and archal CLI |
| GPU | No GPU shapes | No |
Common Questions
Does Archal run agent code?
No. Archal provides stateful simulations of SaaS APIs such as GitHub, Slack, Stripe and Linear; it is a test double, not a compute sandbox. Run the agent itself in CreateOS Sandbox and point its integrations at Archal's REST or MCP endpoints.
How does Archal reset state between test runs?
State persists between calls inside an Archal sandbox, and a reset restores every environment to its declared baseline. On the compute side, CreateOS Sandbox can fork a paused sandbox so each test starts from the same agent state.
What does Archal cost?
$0.10 per minute per environment, prorated by the second, with no subscription; failed provisioning and cold-start time are free. Signup gives $5 after verification plus $15 when the first sandbox is ready, with no card required.
