UniBee is an open-source subscription billing platform built for SaaS, Fintech, and AI startups. It helps you manage the entire subscription lifecycle from creating plans and trials to handling upgrades and renewals. The platform automatically meters usage-based charges, generates compliant invoices in multiple currencies, and recovers failed payments through smart dunning logic. You can self-host the core platform for free to avoid vendor lock-in, or choose their affordable cloud plan.

What to expect from an ideal product
- UniBee automatically tracks and meters your customers' usage in real-time, so you don't have to manually calculate what each user owes based on their consumption
- The platform lets you set up flexible pricing tiers and usage thresholds that trigger different billing amounts without writing custom code
- You can create hybrid billing models that combine fixed subscription fees with variable usage charges, giving you more revenue options than simple flat-rate pricing
- Built-in invoicing generates accurate bills that break down both subscription and usage costs, making it easy for customers to understand their charges
- Smart payment recovery features help you collect money from failed usage-based transactions, which tend to vary more than predictable subscription payments
