Why I Built It
I kept reaching for SEO tools mid-development and every option was either paywalled, slow (server-side crawl), or privacy-invasive. I wanted something that worked like DevTools — instant, local, always there.
What It Does
Open any webpage → open the side panel → click Re-Scan.

The Privacy Part
RankForge injects a script into the active tab only when you click Re-Scan, reads the DOM, returns results to the panel. Nothing hits an external server. Ever.
