About
I build SPAs. SEO tools couldn't see them. So I built Pinealizer.
Most SEO tools were written for 2015 server-rendered HTML. They miss 80% of the modern web (React, Vue, Svelte). I built one that doesn't.
Pattern is always the same. You ship a beautiful single-page app. Marketing runs it through a popular SEO tool. Tool reports zero content, because it never ran your JavaScript. Tool reports broken schema, because it parsed the empty shell instead of the rendered DOM. Tool reports your competitors are winning even when their HTML is worse, because their HTML is what the crawler sees.
Got tired of explaining this to clients. Got tired of writing one-off scripts to prove the page was fine. So I built Pinealizer. Real headless browser. Runs your JavaScript. Waits for the React tree to mount. Then audits what the engines actually see. Then it repeats the same crawl as GPTBot, ClaudeBot, and PerplexityBot, because they read pages differently from Google and they decide whether you get cited in AI answers.
The person who finds the problem should be the one writing the code that fixes it. Strategy decks do not ship features. Pinealizer does.

Founder · Pinealizer
Full-stack engineer. Deep React, TypeScript, Node, and Postgres. Years building SPAs and watching SEO tools fail to render them. Pinealizer is the audit engine I wish I had. Real browser. Real JavaScript. Real AI bot simulation. Real fix steps for the framework you actually use.
Why now
2024 broke classical SEO. 2026 is the window.
ChatGPT, Perplexity, Gemini, and Google AI Overviews rewrote how people find answers. Backlink farming does not move you in AI search anymore. What moves you: whether your page parses cleanly, whether your schema is valid, whether your content answers the question directly, whether AI bots can crawl your JavaScript at all.
Pinealizer is built for that shift. 938 audit checks across 26 disciplines. 9 AI search engines tracked per scan. Real Playwright rendering with bot user-agent swaps. CMS-specific fix steps for WordPress, Shopify, Next.js, and 30 more. Free tier. No card. Founder-built.
