Questions, answered

Frequently asked questions

Does ATLocal2Prod upload my page content?

No. Collection, analysis and storage happen locally. There is no required backend, analytics service or remote AI API.

Can it audit localhost and staging pages?

Yes. It is designed for localhost, private IP, staging, preview and production pages. Browser access still depends on permissions and the page itself.

Which browsers are supported?

Dedicated packages are generated for Chrome, Microsoft Edge and Mozilla Firefox.

Can I use it in CI?

Yes. The CLI supports quality gates, policy files, baseline comparisons and CI-oriented SARIF and JUnit XML exports.

Is GEO/AEO analysis powered by AI?

No. The checks use deterministic, confidence-labeled heuristics that run locally and remain explainable.
