About

What is Hopx?

Hopx offers secure, isolated sandboxes for executing untrusted code, specifically designed for AI agents and autonomous systems. It leverages Linux micro-VMs that launch in approximately 100ms, providing hardware-level security and kernel isolation superior to containers. Users can run Python, JavaScript, Bash, and Go code with real-time streaming output, background execution, and full filesystem operations. Hopx supports various use cases including validating AI-generated code, running long-running jobs, CI/CD testing, data processing, and even desktop automation. The platform provides a simple SDK for integration and an MCP server for IDEs, ensuring code execution is safe, fast, and scalable.

FAQs

What is the startup time for a Hopx sandbox?

Hopx sandboxes leverage pre-built snapshots and Firecracker microVMs to achieve near-instant cold starts, typically spinning up in approximately 100 milliseconds. This allows for rapid execution of code and agents without significant delays.

What programming languages can I run in Hopx sandboxes?

Hopx supports multi-language execution, allowing users to run Python, JavaScript, Bash, and Go code within the secure, isolated micro-VM environments. This flexibility caters to a wide range of development and testing needs.

How does Hopx ensure the security of untrusted code execution?

Hopx utilizes Firecracker microVMs, which provide hardware-level security and kernel isolation. This approach offers a higher degree of security compared to traditional containers or serverless functions, preventing untrusted code from impacting the host system.

Can Hopx sandboxes run long-duration tasks?

Yes, Hopx sandboxes are designed for continuous operation without execution time limits. They can run agents, notebooks, or jobs for hours, days, or even weeks, maintaining full state persistence for long-running processes like data transformations or background workers.
