Overview

Hopx provides fully isolated Linux micro-VMs that spin up in ~100 ms, ideal for running AI agents, notebooks, or untrusted code safely at scale. Each sandbox uses Firecracker microVMs for hardware-level security and kernel isolation, offering full state persistence and SDKs for Python, JS, Go, .NET, Java, and PHP. It features no cold-start lag and no runtime limits, ensuring raw performance and security for AI-driven workloads and dynamic applications.

FAQ 5

What is Hopx?
Hopx provides fully isolated Linux micro-VMs that spin up in ~100 ms, ideal for running AI agents, notebooks, or untrusted code safely at scale. Each sandbox uses Firecracker microVMs for hardware-level security and kernel isolation, offering full state persistence and SDKs for Python, JS, Go, .NET, Java, and PHP. It features no cold-start lag and no runtime limits, ensuring raw performance and security for AI-driven workloads and dynamic applications.
How to use Hopx?
Users can interact with Hopx via its SDKs available for Python, JavaScript/TypeScript, Go, .NET, Java, and PHP. The process involves installing the SDK (e.g., `npm install @hopx-ai/sdk`), creating a sandbox instance (e.g., `Sandbox.create({ template: 'code-interpreter' })`), executing code within the sandbox using methods like `runCode()`, and then cleaning up the sandbox. The SDK allows for various operations including code execution, real-time output streaming, file operations, shell commands, process management, and desktop automation.
What is a Bunnyshell Sandbox?
A Bunnyshell Sandbox (Hopx) is a fully isolated Linux micro-VM that spins up in ~100 ms, perfect for running AI agents, notebooks, or untrusted code safely at scale.
How is it different from containers or serverless functions?
Hopx uses Firecracker microVMs which provide hardware-level security and kernel isolation, offering a level of security far beyond containers or serverless functions.
Do I need a credit card to get started?
No, a credit card is not required to get started with Hopx. You can start for free and receive $200 in free credits.
