The honest brief
Vanna
Trains a RAG layer on your own schema, queries and docs so generated SQL matches your warehouse, instead of guessing from the schema alone.
- MIT-licensed open-source core
- Learns your schema via RAG training
- Works with major warehouses and LLMs
- Returns DataFrames and Plotly charts
- Accuracy depends on the training data you feed it
- Hosted enterprise features are paid
- Setup assumes Python familiarity
Wren AI
Self-hostable Apache-2.0 GenBI with a semantic layer that grounds agent SQL across 20+ databases — where Genie, Julius, and Hex are closed SaaS.
- Self-host via Docker or use managed cloud
- Semantic layer grounds SQL, cuts hallucination
- Many warehouses and databases via one engine
- LLM-agnostic: OpenAI, Claude, Gemini, Ollama
- 2026 pivot froze the original GenBI UI at v1
- Best-tested on OpenAI; other models less so
- RBAC, auditing, row-level security are paid
- Docs split between v1 app and new core
