Autumn: Streamlining Stripe Integration with an Open-Source Billing System

Autumn is an open-source project simplifying Stripe integration for developers. It lets you build any pricing model—subscriptions, credit systems, usage-based billing, custom plans—with minimal code. No more wrestling with webhooks, upgrades/downgrades, cancellations, or payment failures. Deploy via cloud service or self-host with a few commands. Three core functions—`attach` (handles purchases), `check` (verifies access), and `track` (records usage)—make billing logic a breeze.
