Show HN: StripeMeter – Open-Source Usage Metering for Stripe Billing

3 geminimir 2 8/29/2025, 5:08:18 AM github.com ↗

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?

Is stripe billing really so bad that os projects need to be built on top to make it work?

Stripe's billing is pretty solid... The problem this project addresses is the “glue” SaaS teams rebuild: real‑time pre‑invoice visibility, exactly‑once metering, customer alerts/caps, and reconciliation.
