Paddle and Lemon Squeezy are both merchant-of-record checkout platforms for digital products and SaaS. Paddle is known for more mature subscription and billing features for a growing SaaS business. Lemon Squeezy is known for the simplest setup for solo makers and indie hackers (now part of Stripe). Neither is objectively "better." The right pick depends on what you're optimizing for.
Choose Paddle if you run a growing SaaS with more complex subscription billing needs. Choose Lemon Squeezy if you want the fastest, simplest checkout for an indie product.
