Usage based billing,
built to be clicked
Meterline is the admin side of an API business. It meters what customers consume, prices it against plan allowances, projects the invoice before the period closes, and records every change with the role that made it.
No signup, no email, no wall. The dashboard opens straight into a seeded workspace, and checkout takes no payment.
Inside the dashboard
What is actually in there
Not screenshots and not a click through prototype. Every screen below is wired to the same data layer and can be opened right now.
Under it
The parts a client normally asks about
Next.js and React with TypeScript, Tailwind carrying the token system, exported as a static site and served from Cloudflare Pages. Every line opposite can be checked on the page rather than believed.
- A working signup and checkout that creates a real account in the dashboard
- Role based permissions you can switch live, with every blocked control saying why
- Server style paging, sorting and filtering behind a query boundary
- Money held in integer cents, never a float
- Light and dark built as one token system, plus a system setting
- Keyboard reachable, focus always visible, dialogs trap focus and close on Escape
- Loading, empty and error states on every screen that fetches
About this build
Built as a showcase, not for a client. Northwind Labs, Kestrel Data and every customer, plan and figure inside are invented for demonstration, and none of them describe a real business or a real result. Checkout is simulated, no payment is taken, and nothing you type leaves your browser. The engineering is real, the companies are not. Source available on request.
Open it and click through.
Nothing is gated and nothing is a mock. Switch roles, issue an invoice, and watch the audit trail record you doing it.
