In their own words
DataLine
DataLine is an AI tool for querying data in natural language and turning results into tables, charts, dashboards, and reports. It can generate and execute SQL from prompts, then lets users edit, save, and rerun the SQL results; chart queries can also be edited and refreshed. Listed connections include Postgres, Snowflake, MySQL, Azure SQL Server, Microsoft SQL Server, Excel, SQLite, CSV, and sas7bdat. The project is open source under GPL-3.0 and offers a free plan, with binaries and a Docker image for installation. It runs on Linux, macOS, Windows, web, and self-hosted environments. The maker says data is accessed and stored on the user's device rather than in cloud storage, and the README says data is hidden from the LLMs used by default. Docker is described as more suitable for business use. Self-hosted mode has basic username and password authentication, while the executable does not; the current setup supports one user. Excel sheets are imported as separate tables, and the import fails if any sheet fails.
Vanna AI
Vanna AI is an open-source, user-aware agent framework that connects language models to databases. Agents can run SQL queries, generate charts, and call custom functionality through tools. Tool Memory records successful interactions and searches earlier queries and tool-use patterns when handling similar questions. Listed language-model options include Anthropic, OpenAI, Azure OpenAI, Gemini, and Ollama. Database integrations include SQLite, PostgreSQL, MySQL, MS SQL, Snowflake, and BigQuery; memory options include demo in-memory storage, ChromaDB, and Pinecone. Vanna can run through Vanna Cloud or by self-hosting, with FastAPI and Flask server choices. Documentation describes user-specific access controls and tool access groups. Explorer costs $50 a month for 20 questions per day, while Team costs $500 a month for 300. Enterprise pricing is custom, with unlimited questions and listed enterprise features. The security FAQ describes the premium backend as in development/demo stage and lists current limitations.
