Local sandboxes for AI agents on your Mac, Linux, bare metal
Hotcell is a self-hostable sandbox SDK designed for developers and AI practitioners who require secure, isolated environments for AI agents on their own infrastructure. Inspired by Cloudflare's Sandbox SDK, it offers a versatile solution that works seamlessly on Mac, Linux, and bare-metal servers, granting full control over resource allocation, token management, and network access. Its user-friendly setup makes it accessible for both human engineers and automated agents, enabling quick deployment and management of AI workloads without relying on third-party cloud providers. One of Hotcell's standout features is its ability to restrict egress traffic while still permitting access to necessary LLM providers, ensuring privacy and security. Additionally, the sandbox creates per-instance tokens that are ephemeral and delete themselves when the sandbox stops, adding an extra layer of security for API keys. Overall, Hotcell empowers developers to build secure, flexible, and scalable AI environments with ease and confidence.
