Looking for an open-source alternative to Channable / Shoppingfeed / Shopping Flux

Hi everyone,

I’m looking for an open-source or self-hosted alternative to tools like Channable, Shoppingfeed / Shopping Flux, or similar product feed management platforms.

The goal would be to manage and transform e-commerce product feeds before sending them to channels like:

• Google Merchant Center / Google Shopping
• Meta catalog
• marketplaces
• comparison shopping engines
• custom XML / CSV feeds

Ideally, I’m looking for something that can handle:

• importing products from an e-commerce platform or CSV/XML feed
• mapping fields between source data and destination formats
• applying transformation rules to titles, descriptions, prices, categories, availability, etc.
• generating multiple export feeds
• scheduled syncs
• error reporting / validation
• ideally API support

I know SaaS tools like Channable and Shoppingfeed exist, but I’d like to know if there is a serious open-source option, even if it requires technical setup.

Has anyone used or built something like this?

I’m open to:

• open-source projects
• self-hosted tools
• n8n / Node-RED style workflows
• ETL / data pipeline tools adapted to product feeds
• custom stack recommendations
• “don’t do this, use X instead” feedback

Thanks.
