Every time I publish something, I check the schema markup. Copy the URL, open a validator, wait for it to load, scroll through the results. Every single time. After nearly three decades of building sites, that habit never went away – it just got old. So I built a Chrome extension that does the same check in one click, without leaving the page.
It’s called Schema Inspector, and it’s free, and it’s live on the Chrome Web Store right now.
It’s Not a New Idea
There are already a few schema checker extensions out there. I’m not going to pretend otherwise – this isn’t some novel invention. But look closely at what most of them ask for when you install: full access to every site you visit, all the time, forever. For a tool I’d be running dozens of times a day, that never sat right with me.
So I built mine differently. Schema Inspector only asks for one permission: activeTab. That means it can only see the page you’re actively on, and only for the second you click the icon. No standing access. Nothing running in the background. Nothing leaves your browser, ever.
“If a tool only needs to read the page in front of you, it shouldn’t be asking for the rest of your browsing history too.”
What It Actually Shows
Click the icon and it reads everything sitting in the page: every JSON-LD block, every microdata attribute, grouped and readable instead of buried in raw code. If a script tag has broken JSON in it, it says so, in plain language, right where you’d normally have to go dig for it yourself. Copy the parsed data with one click if you need it somewhere else.
That’s the whole tool. It doesn’t validate against the schema.org spec, and it doesn’t check Google’s rich-results eligibility – Google’s own Rich Results Test already does that better than I ever could. Schema Inspector answers a smaller, faster question: what’s actually on this page, right now, before you even think about running a real validator.
