Open-source text-to-SQL agent for querying databases in plain English
Updated
Vanna AI is an open-source SQL agent that lets users query company databases in natural language. It supports multiple databases, multi-turn conversations and access-controlled use. The framework is on GitHub and can be self-hosted with pip.
You install the open-source package, connect an LLM and a database, and train or provide context such as schema and sample queries. Users then ask questions and the agent generates and runs SQL. A hosted option adds access control, a vector memory, secure file system, observability and audit logs.
Developers and data teams who want a text-to-SQL layer inside their own apps or internal tools use Vanna. It suits teams comfortable with Python and self-hosting. Business users typically reach it through an interface a developer builds.
Vanna is open source, so the framework is self-hosted at no license cost, and you pay your own LLM and infrastructure costs. The site links to a pricing page for hosted features, and details are listed there.
Chat2DB is a database client with AI chat for SQL, aimed at developers working in a desktop tool. DataGPT is a commercial AI analytics product for business users. Veezoo is an enterprise natural-language analytics platform built around a semantic layer.
