Overview

Autumn is an open-source billing layer that runs on top of Stripe. Stripe still processes payments and holds the subscription; Autumn becomes the system of record for which plan a customer is on, what features they can use and how much usage or credit they have left.

Developers use three functions: attach returns a Stripe Checkout URL or performs an upgrade or downgrade, check tells you whether a customer may use a feature, and track records usage. That replaces custom webhook handling for upgrades, cancellations and failed payments, and makes it easier to change pricing later.

The hosted service is free up to $8K of monthly billing volume. Pro was shown at $375 a month for $50K of monthly billing volume, with warehouse sync and support for RevenueCat and Vercel as billing sources. The Apache 2.0 code can be self-hosted, and the company is Y Combinator-backed.

Pricing and plans

Free tier

Cloud Free plan: up to $8K monthly billing volume, 10,000 customers and entities, 10M API requests, CLI and MCP, community support

At the limit Not stated The vendor does not say what happens at the limit, or we have not found it yet.

Plan Price What you get
Free $0/mo 8K monthly billing volume, 10M API requests, community support
Pro $375/mo Shown at 50K monthly billing volume; 20M API requests then $5 per 1M; warehouse integration; Stripe, RevenueCat and Vercel billing sources
Enterprise Custom Unlimited billing volume, event discounts, implementation help
Self-hosted Free Apache 2.0 code; depends on several services

The Pro price on the pricing page is tied to a monthly billing volume slider; $375/mo was the figure shown for $50K of monthly billing volume, and other volumes may price differently. Stripe processing fees are paid to Stripe separately. The README says self-hosting depends on several services and points to Discord for help.
