Overview

Cloudflare (NYSE: NET) is a publicly traded connectivity cloud company founded in 2009 and headquartered in San Francisco. In the AI Code Sandboxes & Agent Runtimes vertical, its primary offering is the Sandbox SDK—a developer tool that provisions secure, isolated Linux container environments accessible via a TypeScript API from Cloudflare Workers, with no infrastructure to manage. Built on Cloudflare's global Containers platform (330+ cities, 125+ countries), the Sandbox SDK supports command execution, file management, background processes, browser terminals, code interpretation, and persistent storage via R2. It integrates natively with Workers AI, Durable Objects, and Cloudflare AI Gateway, making it purpose-built for AI agents that need to run untrusted or LLM-generated code at scale. The SDK reached general availability during Cloudflare's Agents Week in April 2026. FY2025 revenue was $2.17B.
