The honest brief

Defog

Powered by its own open SQLCoder model rather than a general LLM, with a privacy stance that never sends your data to the model.

  • Purpose-built SQLCoder model
  • Strong data-privacy stance
  • Connects to many DBs and warehouses
  • YC-backed (W23)
  • Pricing not publicly listed
  • Small team and product
  • Scope focused on SQL analytics

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

When to pick which
