Scalpel SEO vs META SEO Inspector
Both run locally and respect your privacy. META SEO Inspector is a fast metadata viewer; Scalpel SEO is a scored audit with previews and hreflang checks.
META SEO Inspector is made by omiod. Facts checked against public sources on 19 July 2026, and linked at the end. Where a source is silent, the table says "Not documented".
META SEO Inspector, by omiod, is a well-liked, lightweight tool for reading the metadata and structured data on a page in one click. It surfaces JSON-LD, Microdata, RDFa, and more, colour-codes issues, flags missing or oversized tags, works in an always-open sidebar, and speaks 11 languages. Its store listing states it does not collect your data.
Scalpel SEO overlaps on the raw metadata, then goes further into a scored on-page audit. This isn't a privacy contest: both tools run locally. It's a question of how much you want the tool to do. Facts about META SEO Inspector come from omiod's page and the store listing.

Which should you choose?
Pick Scalpel SEO if
You want a scored audit: a weighted grade, SERP and social previews, schema completeness against rich-results rules, live hreflang validation, and exports.
Pick META SEO Inspector if
You want a fast, lightweight, multilingual way to read a page's metadata and structured data and catch missing or oversized tags, with a smaller permission footprint.
Our take
META SEO Inspector is a genuinely good tool and we won't pretend otherwise. For quickly reading what's in the head of a page, in your language, it's excellent, and it's privacy-respecting.
Scalpel SEO is the heavier instrument: a weighted score you can track, pixel previews of how the page renders in search and social, schema completeness against Google's rich-results rules, and hreflang checks that actually fetch the alternates. Reach for it when you want an audit rather than a viewer. Both keep your data on your machine.
