These tools provide the foundational engines required to execute portable, high-performance binary code across diverse environments. They allow you to bridge the gap between low-level system efficiency and the flexibility of platform-agnostic development by isolating execution within a secure, sandboxed space. When selecting an option, prioritize the runtime's memory footprint, startup latency, and how well its host interface layer integrates with your existing codebase.
