Origin & Philosophy
VPA was started as an improved, token-effective alternative to Assembly and C, designed from day one to be emitted directly by LLMs and AI Agents with mathematical memory safety guarantees and zero runtime overhead.
Alignment with Cloudflare Computer (@cloudflare/computer)
"Your agent needs a computer, not a container." VPA compiles to an ultra-compact 42.2 KB WebAssembly binary that executes inside Cloudflare V8 Edge Isolates in < 0.2ms with zero Python dependency.
