Plyxo: Self-hosted CRO+SEO+LLM tool
Free, open-source AI tool for CRO, SEO & AI-search citations
What it does
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.
Open-Source AI-Powered CRO, SEO, SXO, AEO & GEO Website Audit Tool. Automated Conversion Rate Optimization, AI Search Visibility (ChatGPT/Perplexity), Core Web Vitals & Visual UX Friction Detection. - pixelfogg/Plyxo-CRO-SEO-AIO-AEO-GEO

The service, as of right now, is the free diagnostic tool (the AI-powered optimization service will launch in late July). Please use the diagnostic tool and offer your feedback on the functionality and interface--any input is greatly appreciated! I hope to keep the diagnostic tool permanently free forever. By using the tool, you may find ways to improve your website; you are welcome to fix those issues on your own. Such a task should be easy if your website is very small; otherwise, you are the ideal customer for Loyae!

I built TraceAIO, an open-source tool that prompts LLMs on your behalf and tells you whether ChatGPT, Perplexity, and Gemini mention your brand — and which competitors and sources show up instead. Yeah, this category smells a bit like a grift, same as early SEO. And I think over time it will become just SEO again, and become about good content. The tool just helps you monitor over time. It queries the browser products through real browser sessions, not APIs, runs on Docker, with an MCP server so you can query your own data through an LLM. No business model, Apache 2.0, self hosted. If you…

Hello HN! Being a software engineer and an SEO guy I wrote a heap of tools and scripts to make my life easier. Now I've decided to share some of them with the community, and made a small site where I will be publishing them. They are all completely free (yes, free forever) and you don't even need to sign up for the site. Just use the thing as you like, no limits. Currently you can access 4 instruments: - Backlink retriever - Thin/weak content analyzer - Traffic trend analysis - Visitor list retriever I am planning on releasing more free tools with time, and trying to stay original by…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
