The official site footer says UniBee is built in Tallinn.
What it is
UniBee is an open-source subscription billing platform available as self-hosted software or a managed cloud service. It supports one-time purchases, recurring and usage-based billing, tiered pricing, promotions, and flexible billing frequencies. Usage metering can track API calls, storage, compute time, or custom metrics so charges can reflect actual usage. Subscription tools include plan changes, pauses, upgrades, downgrades, trials, add-ons, and lifecycle automation. UniBee can generate invoices, customize templates, handle taxes, and email invoices or provide PDF downloads. It supports multiple payment gateways, including Stripe and PayPal, with routing and fallback options. The listed integrations include more than 25 services, and revenue analytics cover MRR, ARR, churn rate, and customer lifetime value. The free Open-source plan is self-hosted, requires manual setup, and includes community support. Starter is $99/month and Business is $399/month. Advanced offers cloud or on-prem deployment, with price not listed. The pricing FAQ says billing is fixed rather than a percentage of revenue, with no hidden platform fees.
