Oggy: OpenGraph Preview & SEO Meta Inspector, by Pablo Sánchez, is a Chrome extension for validating how pages appear when shared and for basic metadata auditing. It renders instant visual previews of shared link cards and runs an on-page SEO metadata check, giving immediate validation and a numeric audit score. The extension runs locally for development workflows, offers English and Spanish interfaces, and keeps a very small installation footprint. It targets web developers, SEO specialists, and content teams needing fast, privacy-aware metadata checks during development.

What social cards and tag outputs does Oggy show?

Oggy provides direct visualizations of how a link will render on major platforms, showing the rendered og:title, og:description, and og:image rather than just raw text. Previews include cards for Facebook, Twitter/X, and Google Search. The extension also exposes raw meta tags in a JSON view and includes a one-click copy action, so developers can extract meta output for debugging or for pasting into bug trackers and editors.

How light is the extension and what browser overhead does it add?

The extension has an approximately 23KiB footprint, which the developer describes as minimal to reduce browser impact. Because Oggy runs entirely inside the browser and does not make external requests, it avoids additional network round trips during inspection. That local execution model keeps interactions responsive while you test pages under active development, especially on short-lived local servers.

Does Oggy keep metadata and browsing data private?

Oggy operates in a privacy-first mode, executing all analysis in the local browser and explicitly declaring no data collection or third-party sharing. The developer states there are no external requests for inspection, so pages on localhost are processed without leaving the machine. This zero-tracking stance supports sensitive development workflows where sending draft content to remote validators is undesirable.

How well does Oggy fit into a developer or QA workflow?

Oggy is purpose-built for prelaunch checks, notably because it supports pages served on localhost, making it possible to fix metadata before deployment. The interface is bilingual, offering English and Spanish, and the extension is available for Chrome across desktop platforms. The developer is an independent author focused on lightweight tools, and user ratings on the Chrome store reflect positive reception from people who use it for quick, iterative testing.

A focused choice for metadata validation, not a full SEO platform

Oggy is a pragmatic option for developers and SEO specialists who need immediate, private validation of how pages will appear when shared. Its tight focus on OpenGraph and meta-tag checks keeps the tool small and browser-resident, which is a trade-off: it supports rapid debugging but does not replace site-wide SEO reporting or analytics suites.
