Platform Capabilities

Everything billing needs. Built in.

Usage Metering

Redis INCR counters, 30-minute batch flush, monthly rollup — zero DB write pressure.

Domain Licensing

Redis-First Speed

Stripe Subscriptions

Webhook-driven plan activation, upgrade/downgrade, trial, and cancellation flows.

Multi-Domain Support

Each plan includes a domain quota. Starter gets 2, Elite gets 50, Enterprise unlimited.
