About

3va is a JavaScript and TypeScript runtime built on QuickJS with capability-based

sandboxing, post-quantum cryptography (ML-KEM / ML-DSA), and WebAssembly support.

Every permission — filesystem, network, environment variables, subprocess execution —

is denied by default and must be explicitly granted per script.

Post-install scripts are blocked unconditionally.

Built-in process supervisor; no pm2 required.

Security

No known CVEs for 3va.

Coverage is best-effort and depends on a winget package mapping to an NVD CPE entry. Absence here is not a guarantee of safety.
