    Hey, HN! You probably know that the ordering of products on Amazon, posts in FB, and search results in Google is personalized for each visitor, as it directly affects conversion, click rate and engagement. But not everyone can afford to hire an army of PhDs to squeeze every penny out of the ranking, and not everyone agrees on the current (im)balance between privacy and profits. So we built Metarank, an open-source and privacy-focused personalization engine. It can rerank in real-time any type of content, using only the data you allow, and optimize metrics you define.

    I created this chrome extension for myself where I track my own behavior locally and recommend myself content from platforms I want content from (youtube/twitter/quora/etc) in a feed. I made it public just in case anyone else was interested. I would rather have control over my own algorithm and own the data. Also, it gives me flexibility. Turns out I do like these feeds just not when I don't own it haha. Let me know what you think of my implementation?

    Hi HN! I wanted to share our product search and recommendation engine that we’ve built for our eCommerce api startup - Rye. For context, Rye lets people query and dropship products from almost any Shopify and Amazon store. One feature we wanted to have as part of our developer experience was a way for them to search and discover specific products to query. We’ve put together a demo marketplace to showcase the engine. Check it out here: https://search.rye.com/ Here’s a blog that outlines how we built it and how you can to:…
