Odoo Environment Tagger is a Chrome extension designed to improve safety for Odoo users managing multiple databases. It allows users to manually categorize their Odoo databases as Production, Staging, or Development, providing clear, color-coded indicators within the Odoo interface. This feature is essential for preventing accidental operations on critical production databases, particularly in environments where multiple setups are in play.

Key functionalities include visual environment banners that enhance clarity for users, a production confirmation warning that activates before database switching, and persistent local storage for each server and database. Importantly, the tool requires no server-side modifications, ensuring a seamless integration into existing workflows while maintaining user privacy by storing all data locally in the browser without collecting sensitive information.
