None

Problem Description

Managing data in code is hard for SRE people.
LangFlow offers a simple NoCode/LowCode UI to build RAG and ingest data into it.

Solution Description

I propose to build a Custom Rest Backend based on the LangFlow RAG framework.
So instead of k8sgpt auth add --backend customrest something like k8sgpt auth add --backend-url http://langfuse:8090 or k8sgpt auth add --backend langfuse --baseurl http://langfuse:8090.

LangFuse has API endpoints that we basically can use instead of an AI model backend.

Benefits

NoCode/LowCode RAG with data ingestion pipeline in the UI.

Potential Drawbacks

No response
