What it is
Sandbox0 is a managed cloud infrastructure service for AI agents. It provides each user or agent with an isolated cloud computer featuring a persistent, automatically growing root filesystem where agents can install software, modify system configuration, and store data. The entire writable filesystem is preserved across pauses, allowing compute to be released between tasks without losing the agent's work environment. Agents can resume to the same sandbox on demand, with files accessible even while paused. The platform supports long-running agents through APIs, SDKs, command-line tools, and templates, with public HTTP entrypoints for agent services. Compute is billed by the second while running; paused sandboxes incur only storage charges for retained filesystem changes.
Systems
- Automatic filesystem growth as storage fills
- Pause compute without losing work or paying compute charges
- Resume to same environment on demand
- Access files while paused without waking compute
- Public HTTP services with auto-resume capability
- Command-line interface (s0 CLI) for agent-native workflows
- Incremental checkpoints to avoid full filesystem copies
- Scoped API keys and team-based access controls
- On-demand file reads without downloading entire filesystem
Pricing
Pricing model: Paid
Compute: $0.015 per GiB-hour (approximately $0.000004167 per GiB-second, billed by the second). Storage: $0.02 per GiB-month for retained incremental RootFS data and memory checkpoints. Network ingress and egress currently free. Object-store GET and PUT requests free. New users receive $5 free credi

Quick answers
- Do I need a credit card to start?
- No. New users automatically receive a one-time $5 usage credit without adding a credit card. After the credit is used, you can add prepaid funds to continue. Automatic recharge is optional and stays off until you enable it.
- What counts as compute time?
- Compute is billed by the second using the sandbox's configured memory limit and running time. The hourly price is an equivalent rate for comparison, not a minimum. Paused sandboxes stop accruing compute charges.
- Are network traffic and storage operations charged?
- No. Ingress is free, egress is currently free, and object-store GET and PUT requests have no per-request charge.
- Do paused sandboxes or storage cost anything?
- Pausing stops compute charges. Retained incremental RootFS data and memory checkpoints cost $0.02/GiB-month, prorated over 730 hours. Snapshot and fork references to the same data are counted once within a team. Shared base images and platform recovery retention are excluded. Each team can retain 2,000 paused sandboxes by default and request a higher quota for free. At the limit, new sandboxes and forks are blocked. Existing sandboxes can still pause, resume, or be deleted, so pausing can temporarily exceed the limit. Resuming is subject to active capacity and available compute credit.
- Can the default quotas be increased?
- Yes. You can request a quota increase for free by emailing contact@sandbox0.ai. Increases are subject to approval. Running compute and retained incremental storage are billed; pausing stops compute charges. The Dashboard shows the effective limits for your team and region.
