Frequently asked questions about Datus.
What Datus is, what each product does, and the questions teams ask most often when adopting an open-source data engineering agent.
What are the Datus products?
One context engine, four ways to use it, from a local terminal to a governed enterprise platform.
Datus CLI
The open-source core: a data engineering agent in your terminal. Point it at your warehouse and your own model, build an evolving context engine, and generate validated SQL. Apache-2.0 licensed.
Learn moreVS Code & Cursor extension
Datus Studio inside your editor. A local-first extension that talks to a Datus-agent web server on your own machine, so data and credentials never leave it. Works in VS Code, Cursor, and other VS Code-compatible editors.
Learn moreDatus Studio
The hosted cloud workspace and the easiest way to start. No install: connect a warehouse and a model, then ask questions right in the browser. Free during early access.
Learn moreDatus Enterprise
Shared context, governance, and long-running agents for teams, deployed in your own environment (BYOC). Adds an org-wide governed semantic layer, RBAC, audit, and SSO.

What is Datus?
Datus is an open-source data engineering agent. It connects to your data warehouse and the LLM of your choice, builds an evolving context engine of your schemas, semantics, and validated SQL, and uses it to plan, generate, validate, and explain SQL across the whole data lifecycle, from exploration to metrics to production ETL.
What is a data engineering agent?
A data engineering agent is an AI system that plans and executes data work end to end: schema discovery, SQL generation, validation, metrics, and pipeline tasks, grounded in persistent context about your specific stack. Unlike a SQL copilot, it does far more than autocomplete a single query.
Is Datus open source and free?
Yes. The Datus CLI and VS Code extension are open source under Apache-2.0 and free to self-host. Datus Studio (cloud) is free during early access, and Datus Enterprise is custom-priced with governance, SSO, and support.
How is Datus different from a SQL copilot or text-to-SQL tool?
A copilot autocompletes one query. Datus carries a persistent, evolving context engine, validates generated SQL against your warehouse, governs what the agent can access, and covers the full lifecycle of metrics, ETL, and monitoring, not just single-query generation.
Does Datus keep my data and credentials private?
Yes. Datus is local-first: the CLI and VS Code extension run on your machine, connect to the warehouse and model you choose, and store context you own. Database credentials live in your local Datus-agent, never in a cloud you do not control.
How do I get started with Datus?
Install the open-source CLI with pip install datus-agent, point it at a data source, and run datus chat. Or try Datus Studio in the browser with no install. See the Quickstart in the docs.
