DataLine

DataLine is a web-based, chat-driven data analysis and visualization tool for non-technical users who want to ask questions without SQL and for developers who need Text2SQL workflows.

Key capabilities include:

• Chat with data to generate tables, charts, and dashboards from natural-language questions
• Text2SQL for querying and manipulating data in connected databases without writing complex SQL by hand
• Data source support for CSV, Postgres, MySQL, Snowflake, and SQLite
• Open source project available on GitHub for its Text2SQL and AI data analysis components

Pricing: Free.

What makes it notable is its combination of a user-friendly chat interface and a developer-relevant open source Text2SQL codebase (RamiAwar/dataline), plus published resources like a blog, privacy policy, and FAQs focused on data security with LLMs.
