Two dashboards for founders running several products, at the same price, both read-only by design. The differences are narrow and specific: how many billing rails they read, whether costs are subtracted, and whether an agent can ask.
TrackMRR’s figures were taken from their own site on 13 August 2026. If something here has gone out of date, it is an error rather than a tactic — tell us and it gets fixed.

TrackMRR reads Stripe, Polar and RevenueCat. If your money also arrives through Paddle, Gumroad, Lemon Squeezy, the App Store, Google Play, a Shopify store or a WordPress plugin, it is not in the total. DevMargin reads all of those:
A revenue dashboard tells you money came in. It cannot tell you whether the product made any, because it never sees the Vercel, Supabase and model bills going the other way. DevMargin subtracts each project’s running costs and shows the figure underneath — and where a cost has not been entered, the margin says — rather than pretending the cost was zero.
DevMargin exposes the portfolio over a read-only MCP endpoint, so Claude or Cursor can answer “which of my apps is losing money after costs” from the editor, against your real figures. No competitor in this bracket offers one.
Your revenue arrives through Stripe, Polar or RevenueCat only, you want the number on your phone today, and revenue on its own answers your question.
Your money is scattered across more than those three rails, you pay real infrastructure or model bills and want to know which product is actually in the black, or you want an agent to read the portfolio for you.
Free for every rail and every project, with 30 days of history. No card, and every key is read-only.
