Agent-native cloud sandboxes for secure AI code execution
Connect MCP-capable clients and agents directly to isolated cloud sandboxes to execute AI-generated code and handle files securely.
Cold-start latency advertised as low as roughly 100ms, with sandboxes deployed in-region and isolation backed by lightweight VMs such as Firecracker.
Support for long-running workflows with storage persistence, snapshot recovery, streaming output and event-triggered reactivation.
SOC2 and GDPR compliance, access control, output tracing and full audit logging designed for running untrusted AI code in regulated environments.

Cloud browsers and web APIs for AI agents
Spin up scalable, sandboxed headless browsers on demand and drive them with Playwright, Puppeteer, Selenium, or the Stagehand framework.
Find relevant websites from a single query and convert any URL into clean HTML, JSON, or markdown built for LLM context.
Authenticate agents and get through login walls, CAPTCHAs, and anti-bot systems so workflows do not stall mid-task.
Inspect sessions with live view, replay, structured logs, and debugging across prompts, model calls, and browser actions.
