ProjectBlock meters AI usage in your app and enforces limits before the bill surprises you. Drop the Python SDK in — or the LangChain callback — and get per-user quotas, real-time counters, audit logs and Stripe billing. Built for solo devs and small AI team
Hi Hunters 👋
I'm Saad, I build solo from Italy between factory shifts.
I built ProjectBlock because every AI side project I shipped had the same hole: I could see the OpenAI bill at the end of the month, but I couldn't see who burned it, or stop a single user from burning it. Adding metering meant writing the same Redis counters + audit table + Stripe glue every single time.
So ProjectBlock is that layer as a service: install the Python SDK (or plug the LangChain callback), and you get per-user and per-key counters, hard caps that fire before the call goes out, audit logs, and usage-based Stripe billing.
It's early and I know it. What I'd love from you: tell me where the SDK feels wrong, and what limit logic you actually need (per-team? per-endpoint? soft warnings before hard blocks?). I'm replying to everything today.
