Hopx

When you're running AI agents or executing code you don't fully trust, you need isolation that's both fast and bulletproof. Hopx delivers exactly that — fully isolated Linux micro-VMs that spin up in approximately 100 milliseconds, purpose-built for AI workloads, notebooks, and untrusted code execution at scale.

Each sandbox leverages Firecracker microVMs for hardware-level security and kernel-level isolation, with full state persistence across sessions. Hopx supports SDKs for Python, JS, Go, .NET, Java, and PHP, and comes with zero cold-start lag and no runtime limits — meaning raw, consistent performance whenever you need it. It's the infrastructure layer serious AI developers reach for when reliability and security both matter.
