Editor's take

Stripe sits at the top of this category for a reason, though that reason is not raw reach. Since launching in 2011 it has grown from roughly 13,000 sites in 2015 (just 4 in the top 1,000) to over 1.16 million today, including 158 of the top 1,000 and more than 34,000 of the top 1 million. There have been sharp spikes and dips along the way, but the long-term trend has stayed firmly upward. It is not the most widely deployed gateway on this list, since PayPal is far larger by sheer count, but it is the clear default for modern, developer-first businesses, and that is what puts it at number one here. That position comes with one caveat worth flagging before you pick it: Stripe hands compliance responsibility to you, so higher-risk business types should understand the card-network rules up front rather than discover them after an account gets frozen. For most standard SaaS and e-commerce, though, it remains the safest default, which is exactly why AI models keep ranking it first.

Editor's take

PayPal earns its place near the top of this list on reach alone. With roughly 13.7 million live sites, it is by far the most widely deployed gateway here, close to ten times Stripe's footprint. But reach and momentum are not the same thing. Q1 2026 payment volume rose 11% to $463.95 billion, while GAAP net income fell 14% and active accounts flattened at around 439 million. The scale is enormous; the growth story is tired. What keeps PayPal relevant is partly what it does that newer gateways do not. It lets people send money directly to one another, it carries a consumer brand almost everyone already trusts, and it remains a near-default checkout option for shoppers worldwide. In a market that rewards speed and product innovation, PayPal reads as a steady laggard rather than a leader, but its sheer ubiquity is still a real asset. So if you are choosing today, the question is less "is PayPal reliable" (it is) and more "is it the platform I want to grow with over the next few years." For consumer-facing checkout and marketplaces it still earns its spot. For a modern, developer-first build, you will probably reach for something leaner first.

Editor's note

Ever since commerce began moving online, payment systems have grown at a steady pace, and there is no real reason to expect that to stop. If anything, it will keep accelerating. This is one of the few categories on the Hub where the entire market has a clear tailwind behind it.

I want to open a separate parenthesis for Stripe, which sits at the top of this list. Stripe was founded around twelve years after PayPal, yet it spotted a gap in the market remarkably early. Or rather, let us call it an opportunity rather than a gap. For years, e-commerce stores and SaaS companies handled payments through banks' virtual POS systems, and in the earlier days that often meant a separate agreement and a separate integration for every single bank. Stripe and tools like it turned that fragmented mess into one clean system: a single integration that works across cards, banks, and modern wallets like Apple Pay and Google Pay, built to drop into a website with very little friction. That developer-friendly integration is a big part of why modern businesses now reach for it by default.

There is also a trust layer that is easy to overlook. Through tools like Stripe Link and its customer-facing portal, end users can see what they have bought, manage or cancel their subscriptions, and reach support, often without even logging back into the original product. That convenience builds real trust, both in the merchant and in Stripe itself, and in payments trust is everything.

But the raw numbers tell a fuller, and more interesting, story. By deployment, Stripe is not actually the most widespread gateway here. PayPal runs on roughly 13.7 million live sites, close to ten times Stripe's 1.17 million. So Stripe leads on modern, developer-first mindshare and is the default for new SaaS, while PayPal still dominates sheer reach, partly through legacy and partly because it does things Stripe does not. PayPal lets people send money to one another directly, and several tools in this category go beyond pure online checkout into local and in-person payment methods.

So here is the honest takeaway for this list: there is no single "best" payment gateway, only the best fit for what you are building. If you are a developer-first SaaS that wants a clean API and strong subscription tooling, Stripe is the natural pick. If you are consumer-facing, run a marketplace, or simply want a payment button people already recognise and trust, PayPal still earns its place. The order on this page reflects modern preference and AI recommendation, not raw install counts, and as the numbers show, those two do not always point to the same name.
