alt Hacker NewsPeople 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.
You say but your landing page almost lists similar features that getlago does including things like "metering" etc. It is ok to be similar of course but I don't really see how you are different than them other than saying that they are focussed on Series B and you are for early stage. So feature wise, I am not seeing a huge difference. I could be wrong of course.
