1. Stripe
Best for developers wanting an all-in-one modern stack
What it does better than Authorize.net
Stripe combines gateway and processing in one account with a modern API, rich documentation, and built-in subscriptions and fraud tools, removing the separate merchant account Authorize.net requires. Flat 2.9% + $0.30 pricing is simpler to reason about.
Where Authorize.net still wins
Authorize.net lets you keep an existing merchant account and negotiated processing rates, which can be cheaper at scale, and it has broader legacy integration support.
Best for: Online businesses that want a modern, all-in-one payments platform.
