Dex by Exmergo is an innovative developer tool designed to turn your standard coding agent into a specialized analytics engineer. Built to integrate seamlessly with popular development environments and CLI tools such as Claude Code, Codex, Cursor, and Gemini CLI—as well as functioning as a standalone Python package—Dex bridges the gap between raw data warehouses and modern dbt projects.

By pointing Dex at your data warehouse and dbt project, it securely maps your schema in a read-only mode backed by a cost guard to protect against runaway queries. Dex intelligently authors data models and metrics, presenting them as reviewable diffs so you maintain full control over changes. Furthermore, it actively monitors and diagnoses your data pipelines, telling you precisely what broke when schema drift or errors occur.
