Autumn

Already used by 100s of developers

The problem: (1) Stripe is low-level, and it’s hard to build usage pricing. (2) When you change pricing, which AI companies do a lot, everything gets ripped out and jumbled. Autumn allows you to build your app's usage-based pricing model in 3 functions, and manages all the billing, webhooks and DB infrastructure as you scale. It manages your customer subscription states, usage balances, and feature permissions. In 3 functions, you can set up any AI pricing model: usage limits, credits, rollovers, centralized billing— all out of the box. It's already being used in production by 100s of developers and by startups with multi-million ARR.
