Fast & affordable sandboxes for AI agents

An AI sandbox is a separate place for an agent to run code, use tools, and work with files. Lizard Sandboxes let agents build, test, and debug in the cloud without running that code on your computer.

Sign in to Lizard, choose a project, and create a sandbox from a ready-made template. Choose base for shell tasks, codex for coding tasks, or interpreter for Python, then select a size and region.

Yes. Run Python scripts with the interpreter template, or use shell commands to run tools and tests. Read command output and save results to files. Each command starts a new process.

Lizard uses a pool of prepared Sandboxes to reduce setup time. Startup time depends on the template, size, region, and available capacity.

Each sandbox runs in its own Kubernetes pod using runc and shares the host kernel. It uses container isolation, without a separate virtual machine kernel. Give the agent only the credentials and access needed for its task.

You choose the lifetime when creating a sandbox, including no automatic expiry for longer tasks. A sandbox stops at its deadline even if a command is running. Commands do not extend the deadline, and idle time does not stop it early.

Yes. Attach Persistent Volumes at /workspace to keep files after a sandbox stops and reuse them in later runs. A volume connects to one sandbox at a time. Storage stays on one node, so export files you need to protect against node loss.

Yes. With access to your project, an agent can deploy apps and databases through Lizard CLI. They run as separate resources on Lizard and keep running after you stop or delete the sandbox.

Yes. Create a separate sandbox for each task so agents can run commands and tests at the same time. The number of Sandboxes you can run depends on your account limits and available capacity in the region.

The Small size costs $0.009/hour for 2 vCPU and 4 GB RAM. Billing runs by the second, including idle time, with CPU, RAM, and sandbox egress included. Persistent Volumes cost extra. Older sandboxes without a size keep their original usage-based billing.

Trial or promo credits, when available in your account, can cover Sandboxes usage. Standard accounts use pay as you go with no monthly subscription. Trial and promo credits can expire; purchased credits do not.
