Hey everyone! 
We just shipped a full RAG feature at https://giselles.ai/ using only the Vercel stack - no external job queues or additional SaaS needed!
The constraints actually led to some interesting solutions:
- Vercel Cron for scheduled processing
- Neon for vector storage
- Pure Next.js for everything else
We wrote up our learnings here: Building a GitHub RAG System with Next.js and Vercel - Design Strategies Under Platform Constraints - Giselle: AI App Builder
Thought it might be helpful for anyone building similar features. Would love to hear if others have tackled RAG differently on Vercel!
P.S. Can’t wait for Vercel Queues to drop
