| Question | Short answer |
|---|
| What is Stella Ops? | A lightning‑fast, SBOM‑first container‑security scanner written in .NET 10 LTS with an Angular 20 web UI. |
| How fast is it? | Warm scans finish in < 5 s on a 4‑vCPU runner; first scans stay < 30 s. |
| Is it free? | Yes – 33 scans / day anonymously. Requesting a free JWT lifts the limit to 333. A gentle reminder shows at 200; exceeding the cap throttles speed but never blocks. |
| Does it run offline? | Yes — download the signed Offline Update Kit; see /offline/. |
| Can I extend it? | Yes — restart‑time plug‑ins (ISbomMutator, IVulnerabilityProvider, IResultSink, OPA Rego). Marketplace GA in v1.0. |
