Using Offline Error Page Builder
Create useful fallback pages with retry, saved work and connectivity guidance.
- Start with Try worked example. Builders already have editable example settings.
- Use Details & settings to adjust the declared inputs, thresholds or component content. Review cards retain source evidence and any supported manual decisions.
- Open Preview for the actual analysis or interactive component. Test keyboard behavior and narrow layouts before relying on generated UI.
- Use Export for task artifacts and the complete workflow ZIP. Save review retains settings/decisions and source fingerprints; file-based projects need the original sources to reopen.

Questions & answers
What does Offline Error Page Builder support?
Create an offline/error-page prototype with recovery wording, saved-work link and an explicit retry demonstration.
What input should I use?
Use the editable example settings. Component builders provide labelled fields, realistic defaults and a live local preview.
What can I download?
A standalone component HTML demo, scoped CSS, JavaScript, markup and settings are included for component generators. Static selector analysis exports evidence instead. All workflows also provide JSON, CSV and a complete workflow ZIP.
Does this run a live website audit or deploy changes?
No. Performance diagnostics use imported evidence, explicit simulations or selected local bytes. Builders export code for you to review and integrate. No URLs are crawled, no service worker is installed and nothing is deployed. Public pages retain approved ads and optional consent-based analytics.
