Plyxo is a free, self-hosted platform that finds conversion friction on your site (with dollar-impact estimates and instant code fixes), runs deep technical/semantic SEO audits, and scores how likely ChatGPT, Perplexity, and Gemini are to cite your pages as answers — something most SEO tools skip entirely. No paywalls, no usage caps. Built on Next.js 16 + Postgres, fully open source under MIT, and yours to run on your own infrastructure.
Hey PH 👋 maker here.
I built Plyxo because I couldn't find a single tool that combined visual CRO auditing,
technical SEO, and — increasingly relevant — "will an AI chatbot actually cite my page"
scoring. Everything else in this space is either a $99+/mo SaaS or a spreadsheet with
400 rows and no clear idea what to fix first.
What it does:
- Screenshots your page and flags CRO friction with estimated revenue impact + copy-paste fixes
- Full technical/semantic SEO audit (schema, Core Web Vitals, E-E-A-T signals)
- AEO/GEO scoring — how likely ChatGPT Search, Perplexity, and Gemini are to cite your page
- Competitor keyword-gap analysis
- Self-hosted, MIT licensed, no paywall
Would love feedback on the AEO/GEO scoring especially — it's the newest and most
experimental part, and I'm curious how it holds up against real-world sites. Happy to
answer anything about the stack, the scoring methodology, or the roadmap.
