DataGauge — Mzed Studio case study

Metrics API and dashboard for MAU, signups, revenue, and MRR across every app you run.

Overview

A metrics API and portfolio dashboard. Developers send events from any app on any stack and see usage and revenue for all of them in one place.

The problem

Developers running several apps have each app's numbers scattered across separate tools, with no single, programmable view of usage and revenue across the portfolio.

What we built

• Event ingest API at the edge that keeps up with bursty traffic and doesn't drop data when something downstream fails
• DAU, MAU, signups, revenue, MRR, and MRR history, ready without writing queries
• Connect Stripe or Polar and get revenue and MRR with no product code
• Read API for single metrics and the whole portfolio, so the same numbers work in your own tools
• Read-only MCP server so AI agents can query metrics
• SDKs for browser, Node, edge, and Convex, plus a dashboard with custom metric cards, trends, and shareable cards

Stack

Cloudflare, ClickHouse, Convex, TanStack Start, React 19, Better Auth, Stripe, Tailwind CSS
