About Marqo
Marqo is an open source repository for an AI-native ecommerce search platform aimed at online brands in fashion, beauty, electronics, and home goods. According to its description, it uses semantic search and personalization, drawing on clickstream, purchase, and event data to interpret shopper intent and return search results and product recommendations. The stated goals are improved search relevance, higher conversion and average order value, and less manual merchandising through automated ranking and optimization.
The repository itself is distributed under an Apache-2.0 license and is written around Python tooling. A notice in the readme states that Marqo's open source project is deprecated and will no longer receive updates, and directs those interested in the product search and discovery platform to marqo.ai. No pricing information is provided in the source.
