Chartsy vs Submetrics

Chartsy is a web analytics product for SaaS founders that combines Stripe and Paddle billing records with website traffic. It calculates MRR, ARR, churn, LTV and cohort retention from invoice data, and includes expansion analysis and unit-economics measures. A tracking script attributes visits and signups to Stripe or Paddle revenue by marketing channel. ChartsyAI converts plain-English questions into charts without SQL; its chatbot handles follow-up questions and explains changes in revenue metrics. Supported sources are Stripe, Paddle Billing, Paddle Classic and BigCommerce. GDPR Mode avoids storing customer names and email addresses while metrics continue to work. Connections to Stripe and Paddle are read-only except for webhook registration. Weekly emails cover subscribers, MRR, churn, plan performance and geographic distribution. Four dashboard templates appear after initial synchronization. MCP supplies read-only data to ChatGPT and Claude.

Submetrics is subscription analytics for indie founders, development agencies, and indie hackers, including SaaS products under $50K MRR. It tracks MRR, ARR, churn, customer lifetime value, expansion, and related unit-economics measures from billing data. The dashboard updates revenue metrics in real time as subscriptions start, expand, contract, or churn. Slack or email alerts can report cancellations, with reasons taken from Stripe metadata. Lifetime value can be segmented by plan, cohort, or acquisition channel, while retention is displayed in cohort heatmaps. The Pro plan adds AI revenue projections for three, six, and 12 months with confidence intervals. Stripe and RevenueCat integrations are live; Paddle is in beta, and three other connections are coming soon. Plans start at $19 a month, with a 14-day trial and no credit card required. Supported platforms are web, iOS, Android, and API.
