Why you'll love Hyperlight
Ultra-Fast VM Creation
Create new micro-VMs in just 1-2 milliseconds, about 100x faster than traditional hypervisor approaches, making it practical to spin up VMs on-demand for individual function calls.
Hypervisor-Level Security
Execute untrusted code with real hypervisor-based protection for each function call, providing stronger isolation than sandboxed runtimes while maintaining exceptional performance.
Minimal Resource Footprint
Extremely lightweight with a 64KB stack and 128KB default heap size, enabling true scale-to-zero capabilities and efficient resource utilization.
Portable Abstraction Layer
Run on Hyper-V, mshv, or KVM across different platforms without changing your code, providing flexibility while maintaining consistent security benefits.

Hyperlight and Edge Actions
Azure's CTO Mark Russinovich at Microsoft Ignite 2024
- Micro-VMs can be started cold in isolation or warm from a pool
- Supports running WebAssembly, JavaScript, and more
- Ideal for serverless platforms and real-time applications
