Most social preview debuggers and meta tag testers today are bloated, slow, or locked behind ad walls and paywalls.
I wanted a clean, browser-native suite of tools that runs 100% client-side with 0ms server latency, so I built OmniSEOtools.
Why Client-Side Matters
Instead of scraping URLs on a remote server, testing your tags and title dimensions directly in the browser gives instant feedback.
Here is what is currently live and open:
- Twitter / X Card Previewer — Test 1.91:1 social card crops and text truncation.
- Google SERP Pixel Ruler — Real-time 600px desktop and mobile snippet simulator.
- LinkedIn Post Inspector — Accurate preview of feed post cutoffs.
The project is built using Next.js (App Router), Tailwind CSS, and is open-sourced on GitHub.
Would love feedback from other developers on what other SEO or meta utilities you'd find useful to have client-side!

i was stuck on the same issue with next.js metadata api not firing on client side, curious how you handled the cache invalidation when the og image url changes
