Salesforce Deploy Tracker is a Chrome extension developed by raul.plesa. It is a free tool that helps users keep track of their Salesforce deployments in real-time for all the organizations they are logged into.

With Salesforce Deploy Tracker, users can easily monitor their deployments and receive desktop notifications for various events such as when a deployment starts, ends, or when the first test fails. This feature ensures that users are always aware of the status of their deployments and can take immediate action if any issues arise.

However, it is important to note that this extension is currently in a preview version, which means that users may experience some instability and encounter bugs. While it provides valuable functionality, users should be prepared for potential issues and provide feedback to the developer to help improve the extension.

In terms of privacy, Salesforce Deploy Tracker scans the browser for all active Salesforce sessions and makes requests on behalf of the logged-in user. Only the organization domain is stored on the user's local storage, and no other information is stored or sent to any third party. The project is open source, and the public repository contains technical information and diagrams on how it handles data.

Overall, Salesforce Deploy Tracker is a useful tool for Salesforce users who want to stay informed about their deployments in real-time. Despite being in a preview version, it offers valuable features and respects user privacy.
