Notch Metrics: Use claude code to build analytics widgets for your notch
Notch Metrics is a Mac app that places business figures inside the MacBook notch. Product Hunt published the launch on 29 October 2026, and the Product Hunt aggregator Buzzing recorded 111 upvotes that day. The product page lists version 0.4.2, requires Apple silicon and macOS 14 or later, and offers a 7-day free trial. Hovering over the notch shows revenue, MRR and subscriber counts. Nine widgets can sit in view at once, in four tile sizes that can be dragged and resized in place.
The security design is the main departure from earlier notch dashboards. According to the Product Hunt listing, each provider key is encrypted as soon as it is pasted and stays on the server, so no app on the Mac can read it. The Mac receives finished figures instead. The service covers 16 sources, including Stripe, Polar, Paddle and Shopify. A connection made on the web appears on every Mac signed into the account, and the layout syncs between machines.
Users can fit as many widgets as the notch allows or switch to a list view. Custom metrics can be written by the user's own coding agent over MCP, so a widget can draw on internal data rather than a fixed provider list. The site describes a yearly plan that covers every connector with no per-integration charge, along with signed and notarised updates.
Why it matters
For a founder, the number most people check is revenue, but the useful signal is often MRR movement and subscriber change. A glanceable view in the notch removes the step of opening a billing dashboard. The more consequential feature is the MCP path. A team can have its coding agent define a widget around its own data, so the metric set is no longer bounded by the integrations a vendor chose to build. Reporting work that once sat with an analytics or data team can move to whoever runs the agent, which raises the importance of reviewing what those agents generate.
The server-held key design is worth studying as a reference for any internal finance tool that touches payment credentials. Encrypting keys server-side keeps them away from every local process, but it also concentrates risk in one service. Operators and investors evaluating similar tools should ask how keys are stored, who can access them, how access is logged and how revocation works. Competitors such as Notch Buddy take the opposite route by keeping the read-only key on the Mac, which gives buyers a clear trade-off to weigh.
