People compare us a lot because they're also another open source YC company that does billing. So definitely some similarities!

I think in practise though we serve a very different segment. Lago is great for high-throughput event metering and mainly target series B+ companies. They don't yet have an offering for feature permissions management (aka entitlements).

Autumn is built more for early stage companies that have payments in-app. Hence we're trying to invest more in the developer experience (eg React hooks), while also providing that abstraction layer for entitlements too.

We absolutely will be adding more payment providers soon. Our biggest requests are Polar and Razorpay for the indian market.

Supporting multiple payment providers would be crucial for true payment infrastructure independence - curious if there's a plugin architecture planned that would make it easier to add adapters for Adyen, PayPal, or regional payment gateways.
