Secure cloud sandboxes for running AI-generated code.

Open-source infrastructure that spins up isolated cloud sandboxes so AI agents can execute generated code safely. Python and JS/TS SDKs cover code interpretation, data analysis, and computer-use desktops, with per-second billing. Self-host or BYOC/on-prem is supported for enterprise.

Secure, elastic sandboxes for running AI-generated code.

Infrastructure for executing AI-generated code in isolated sandboxes — each a full composable computer with a dedicated kernel, filesystem, network stack, and allocated CPU, RAM, and disk. Sandboxes start in under 90ms, snapshot for persistence, and are driven programmatically through SDKs (Python, TypeScript, Ruby, Go, Java), an API, and a CLI. AGPL-3.0 and available as a managed service, self-hosted stack, or hybrid where you bring your own compute.

Perpetual secure sandboxes that keep AI agents on warm standby.

Blaxel is serverless infrastructure for AI agents: secure sandboxes that spin up in seconds, hibernate after a second of inactivity at zero idle cost, and resume in roughly 25ms with full memory and filesystem state intact. It co-hosts agents, MCP servers, and batch tasks on one backbone, and adds an LLM gateway with caching, rate-limiting, and observability. Snapshots and forking let teams branch agent state for rapid experimentation.

Cloud Devboxes and benchmarks for running AI coding agents at scale.

Runloop provides isolated, cloud-based development environments — "Devboxes" — where AI coding agents safely execute code with full filesystem, build-tool, and compiler access. Teams spin up thousands of Devboxes on demand for large-scale agent tasks and tear them down when done. A benchmarking suite lets you evaluate and compare agents on standardized tests, and enterprise deployments add compliance and VPC options.
