Make the invisible parts of a website inspectable
Manifesto collects several technical publishing concerns into one website scan. It examines application manifests, social-sharing metadata, favicon references, structured data and selected HTTP security headers, then presents category-specific findings.
The interface pairs those findings with editors intended to help prepare revised configuration. That makes it a development aid for working through metadata rather than a score with no explanation.
A focused inspection toolkit
- PWA manifest checks and configuration editing.
- OpenGraph and social-card metadata.
- Favicon formats and size references.
- JSON-LD structured-data validation.
- Selected header observations and category scorecards.
Useful checks with limited scope
The application uses Next.js/React, Cheerio parsing and Zod validation, with Monaco-based editors. A scanner can only report what it observes under its current rules and network conditions.
Its scores do not constitute a full accessibility audit, penetration test or guarantee of search-engine outcomes. The featured image is a conceptual metadata workspace, not a real website report.
