What is Air-Gapped?

Running with no outbound network access at all, in an environment physically isolated from the internet.

Air-gapped is stricter than self-hosted. The installation cannot phone home for licence checks, telemetry, rule updates or vulnerability feeds, so everything must be transferable through an offline update bundle.

This is classified and critical-infrastructure territory. Ask specifically how the vulnerability database is refreshed offline, because a scanner with a stale advisory feed reports confidently on last quarter's threat landscape.

Top 8 Air-Gapped tools

Every tool in the directory documented as supporting Air-Gapped, 7 fully, 1 partially, with what its own documentation says.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.

    Code and secret scanning run offline via CodeQL bundle sync; Dependabot SCA needs GitHub Connect.

  5. 5
    GreptilePR ReviewEnterprise

    Docs state the entire service can run air-gapped; any OpenAI-compatible endpoint allows a local model.

  6. 6
    QodoPR ReviewEnterprise

    Air-gapped is a first-class column in the deployment matrix; local LLM gateway supported via api_base.

  7. 7

What to look for

  • How vulnerability data and rules are updated without network access
  • Whether licensing works fully offline
  • Which features silently degrade, since AI review usually cannot work at all
  • Documented installation procedure rather than a bespoke engagement
