Autumn is an open-source layer over Stripe that abstracts this into a few lines of code. Here’s how it works:
First, create a pricing model in Autumn
Define your product’s features and pricing in their UI. You have the power to charge however you want:

Autumn synchronizes the pricing you create into Stripe.
Then, integrate the pricing model into your application
When your user chooses a plan, call Autumn’s attach function and a corresponding Stripe checkout URL will be returned.

When your user tries to use a feature, check if they have access by calling Autumn’s entitled function.

If it’s a usage-based feature, you can also send us usage events to track.
That’s it. They take care of the subscription state, what the customer has access to, upgrading/downgrading plans, and all other logic.
Historically, feature flagging and metered billing have been separate products. Autumn combines them into a seamless experience, allowing you to fully decouple pricing and billing logic from your code.
AI is changing the way we think about software’s value, and enterprise clients are demanding optionality. Today’s software demands more flexible pricing, their customers are choosing Autumn to handle it all while moving faster.
It’s fully open-source, and easy to self-host. You can take the reigns at any point and customize Autumn to your every need.
