We built StripeMeter, an open-source usage metering platform that plugs directly into Stripe. It solves the classic SaaS pain of “why is my bill higher than expected?” by giving both developers and customers real-time usage tracking with live cost projections. Why it matters:

- Transparency: Customers see exactly what Stripe will bill them (within 0.5% parity).

- Exactly-once guarantee: No double billing, ever.

- Fast & scalable: Sub-minute freshness with Redis + Postgres counters.

We’d love feedback from SaaS builders, especially if you’ve struggled with Stripe’s metered billing. Does this solve a real pain for you? What would you need before trusting it in production?
