UniBee is an open-core billing infrastructure built for SaaS and AI companies with complex pricing and scaling needs. It handles the full billing lifecycle - subscriptions, usage-based and hybrid pricing, invoicing, payments, and revenue analytics - without locking you into rigid SaaS workflows. UniBee can be deployed as a fully managed cloud or self-hosted in your own infrastructure, giving teams full control over data, pricing logic, and integrations. Designed for companies that outgrow template-based billing tools, UniBee helps engineering and finance teams move faster, experiment with pricing safely, and scale globally without re-architecting their billing stack.
