SerpPrism
Run 11 SEO checks on any page. Nothing leaves your browser.
Eleven free SEO tools that run entirely in your browser — nothing is uploaded, ever. Check meta tags, SERP snippets, robots.txt, headings, JSON-LD, Open Graph and hreflang. For anyone who audits pages they'd rather not push through someone else's server.
I'm Hongtao. I built SerpPrism because every SEO tool I tried wanted me to paste a URL into someone else's box — which meant handing a client's staging site, or a page behind a login, to a server I don't control.
So everything runs client-side. Paste HTML, a URL, or a file — parsing happens in your tab. No account, no upload, no log.
Eleven tools: meta tag generator, SERP preview, robots.txt tester, heading analyzer, schema markup generator, Open Graph preview, hreflang generator, UTM builder, keyword density, readability, llms.txt.
The guides are built from surveys I ran against real sites — 78 domains for robots.txt, 62 homepages for Open Graph, 61 for JSON-LD — with raw data and method published so you can check the claims rather than trust them.
Ask me anything about the parsers.
