Capsule (WebAssembly)

This entry runs no foundation model. Every finding below is quoted to the vendor’s own document, or marked not disclosed where the vendor publishes nothing.

WebAssembly-based task isolation for Python AI agents — deny-by-default sandbox with zero privileges, strict fuel metering to prevent runaway loops, and structured JSON result envelopes

Model provenance

No foundation model. Capsule (WebAssembly) does not run one, so this criterion does not apply and is excluded from the grade rather than counted against it. It is a Rust framework for building high-performance network functions on Intel's DPDK, manipulating raw packets with a type- safe API — networking systems software with no AI component whatsoever. Established from the product’s own public documentation and what it does. If that is out of date, tell us at right of reply.

Who controls it

Not yet assessed. We publish a sovereignty position only where the vendor documents one — we do not infer it from a domain or a company name.

How this grade is set

Vannus publishes a nine-dimension trust framework — data sovereignty, training privacy, compliance posture, operational resilience, exit portability, and more. The heaviest criterion asks whether the tool builds its own AI or resells someone else's model; where the vendor discloses it, the grade cites the vendor's own documentation. No paid placements — scoring is walled off from affiliate revenue. See the methodology →
