what is mrrbar fr?

MRRbar is a Chrome browser extension that shows your business revenue metrics directly in the toolbar without needing to open a separate tab. MRR stands for Monthly Recurring Revenue, which is a common way SaaS and subscription businesses measure how much income they are generating each month. The extension connects to Stripe and Lemon Squeezy, two popular payment platforms, by polling their APIs every five minutes. Once connected, it shows a live badge on the extension icon with either today's revenue or MRR at a glance. Clicking the icon opens a popup with a fuller dashboard: today's revenue, MRR, ARR, which stands for Annual Recurring Revenue, new subscriptions or sales, active subscriber count, churn rate, the rate at which subscribers cancel, and how today's revenue is pacing compared to yesterday. There is also a lightweight achievement system with 12 unlockable milestones tied to business growth, such as receiving your first payment, hitting revenue milestones, or maintaining streaks. Achievements can be shared on social media. Desktop notifications alert you when a new sale comes in or an achievement unlocks. Your API keys are stored using Chrome's built-in encrypted storage and never sent to any external server. Setup requires creating a read-only restricted key on each payment platform and pasting it into the extension's settings. The extension is built with vanilla JavaScript and no external dependencies, so there is no build step required. It is licensed under GPL v3 and can be loaded in developer mode directly from the cloned repository. A roadmap in the README lists planned additions such as a light mode, a seven day revenue sparkline, multi account Stripe support, and a Slack or email digest for future releases.
