Plyxo: Self-hosted CRO+SEO+LLM tool

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.
