Local-only · no network dependency
A verifier you can actually trust
The verification report is a strategic asset - useful to recipients, developers, security teams, auditors, and gateways alike.
Local-first
The same memory-safe Rust core, compiled to WebAssembly. Files never leave your device.
Layered results
Distinct verdicts for container safety, integrity, identity, freshness, and policy.
Radical transparency
Every passed, skipped, and unavailable check is shown - never a single misleading badge.
Sub-millisecond
Cryptographic verification in 0.2–0.6 ms, online or fully disconnected.
Embed verification everywhere
Use the CLI in CI, the WASM core in your app, or the Gateway at your boundaries - the same engine, the same deterministic result.
