UniBee
Subscription billing platform with usage metering and insights
UniBee is an open-source billing platform designed for SaaS, fintech, and AI companies. It manages the full subscription lifecycle, including trials, renewals, and complex usage-based metering for API calls or tokens. You can automate global invoicing, handle multiple currencies, and use smart dunning to recover failed payments. Since it’s open-source, you can self-host to avoid vendor lock-in or choose our managed cloud. It connects to your existing payment gateways and provides real-time insights into MRR, churn, and customer lifetime value from one dashboard.
