OnPage Pro — Self-Hosted PHP On-Page SEO Analyzer 

OnPage Pro is a privacy-first, self-hosted SEO analyzer you run on your own machine or server. Audit titles, metas, headings, internal links, images, schema, robots/indexability, and more — with no URLs or content sent to third parties. Includes a clean web UI plus a powerful CLI for batch jobs and automation.

Why self-hosted?

• Private by design: Your pages and results never leave your environment.
• Fast & unlimited: No rate limits, no credit meters.
• Scriptable: Automate recurring audits via CLI + cron.
• Familiar stack: PHP 8+, SQLite/MySQL.

Notes

OnPage Pro does not send data externally. For very large crawls, ensure adequate PHP memory and max execution limits. Do not host on the public internet, this is designed to be hosted locally or on a private secure server.

• UI: Analyze from a friendly dashboard.
• Headings & Meta: Missing/duplicate titles, meta length, multiple H1s, empty headings.
• Internal Links: Orphaned pages, inlink counts, anchor text patterns, suggested links.
