Products that do what Amazon-like product recommendation engine to power open-source eComm does
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:…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…

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. We made a lot of…

Hi HN! I built Agora as a side-project leading up to the holiday season. I wanted to find an easier way to find Christmas gifts, without needing to go store-by-store. My wife asked me for a a pair of red shoes for Christmas. I quickly typed it into Google and found a combination of ads from large retailers and links to a 1948 movie called 'Red Shoes'. I decided to build Agora to solve my own problem (and stay happily married). The product is a search engine that automatically crawls thousands of Shopify stores and makes them easily accessible with a search interface. There's a few additional…

I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers. tl;dr $ alias rip="curl -G -H 'Accept: text/plain' --url https://dontbeevil.rip/search --data-urlencode " $ rip 'q=Heartbleed bug' DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions. It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN,…

Hey HN! I got nerd-sniped by Bloom Filters this weekend, specifically for searching datasets with high "cardinality" (number of unique items). They're an _amazing_ data structure that, at a fixed size, tracks potential set membership. That means unlike normal b-tree indexes, they don't grow with the number of unique items in the dataset. This makes them great for "needle in a haystack" search (logs, document) as implementations like VictoriaMetrics and Bing's BitFunnel show. I've used them in the past, but they've never been center-stage in my projects. I wanted high cardinality keyword…

Hello everyone! I’ve been building an Open Source Ecommerce framework for Angular called Daffodil. I think Daffodil is really cool because it allows you to connect to any arbitrary ecommerce platform. I’ve been hacking away at it slowly (for 7 years now) as I’ve had time and it's finally feeling “ready”. I would love feedback from anyone who’s spent any time in ecommerce (especially as a frontend developer). For those who are not javascript ecosystem devs, here’s a demo of the concept: https://demo.daff.io/ For those who are familiar with Angular, you can just run the…

Swirl Is an Open-Source Search engine alternative to Algolia, and the likes. But Swirl queries anything with an API then uses Large Language Models to re-rank the unified results without copying any data! If the database has an API it can connect to and provide search functionality. You can use it to generate AI insights over a large and spread-out database. Check the website: https://swirl.today/ GitHub: https://github.com/swirlai/swirl-search
