What It Is

MRR Calendar is a public metrics showcase tool for SaaS founders and indie developers. Its core idea is to “turn Stripe revenue into a GitHub contribution graph.” By connecting to Stripe, it displays subscription revenue, sales, and MRR changes, organizing the data into public pages, live activity feeds, leaderboards, and milestone cards for building in public.

Core Features and Integrations

Based on the available content, the product focuses on revenue visualization and public sharing. Features include a revenue heatmap, subscription/sales event feed, MRR leaderboard, automatic goal detection, and milestone cards generated when users hit achievements such as $10K MRR, 2,000 commits, or 5,000 followers. It also emphasizes data from “verified sources”: Stripe for revenue, GitHub for commits, and X/Twitter for followers. It can sync updated metrics after each sale to a GitHub Profile and X/Twitter Bio. In addition, it can send MRR, subscription count, daily commits, and similar metrics to desktop pixel displays such as Ulanzi TC001 Smart Pixel / Awtrix.

Pricing and Business Model

The terms indicate that MRR Calendar offers paid plans, billed as prepaid subscriptions with automatic renewal. Payments are handled by Stripe, and users can manage their subscription in billing settings. However, the page does not disclose specific plans, pricing, free allowances, or trial duration; only a “Try the demo” option is visible. As a result, pricing transparency is relatively weak for procurement evaluation.

Pros and Cons

Its main strength is its very clear positioning: it is not a traditional BI or financial analytics tool, but a way for early-stage founders to turn revenue, code, and social growth into a credible public narrative. Automatic Bio/Profile syncing also reduces manual maintenance. The limitations are also obvious: it depends heavily on Stripe, so it offers limited value for teams using domestic payment methods, bank transfers, or non-subscription revenue models. Publicly displaying MRR is also unsuitable for privacy-sensitive teams, enterprise-sales businesses, or more mature B2B companies. The main content also does not provide enterprise-level information such as permission management, audit logs, SOC 2/GDPR compliance, or API access.

Who It’s For and Access from China

It is best suited for indie developers, micro-SaaS teams, and creators building in public who want to demonstrate continuous shipping and real revenue to potential customers, investors, or followers. Use from mainland China is “partially restricted”: the site itself cannot be assessed from text alone, but among its dependencies—Stripe, GitHub, and X/Twitter—X/Twitter usually requires a proxy, and Stripe payments may not be available to mainland China entities. If targeting the domestic Chinese market, alternatives could include Stripe Dashboard, Baremetrics, ChartMogul, or domestic data dashboards / self-built public pages.
