our call
Start with Lengow — highest vibe code, weakest moat.
Lengow
You can easily build a script to transform a Shopify catalog into a Google Shopping XML feed or Amazon SP-API payload using AI.

- Basic XML and CSV feed generation for Google Shopping, Meta, and Pinterest.
- Catalog attribute mapping and static string replacement rules.
- Simple product filtering (e.g., exclude out-of-stock items).
- Basic Shopify catalog ingestion via Webhooks or GraphQL API.
what you lose
- Pre-built connectors for over 1,600 regional and global sales channels.
- Automated handling of API spec changes and mandatory category taxonomy updates.
