MRRbar is a free Chrome extension designed to provide real-time revenue tracking directly in your browser's toolbar. This tool is particularly beneficial for indie founders, allowing them to connect their Stripe and Lemon Squeezy accounts to display key financial metrics without the need to constantly check their dashboards.

With features like revenue pace comparisons, sale notifications, and achievement milestones, MRRbar enhances productivity by eliminating the need for frequent dashboard visits. The extension also prioritizes user privacy, ensuring that sensitive keys remain on the user's device without any tracking. MRRbar is open source and designed specifically for indie founders, making it a valuable tool for those looking to streamline their revenue management.
