PayPal vs Stripe Comparison

Both work great. Choose based on your market:

• Stripe — lower fees (2.9% + 30¢), better developer experience, more countries
• PayPal — higher trust with older customers, buyer protection brand, no card-entry friction for PayPal users

Most sites enable both so customers pick their preferred method.
