Overview

LemonSqueezy is a merchant of record payment platform designed for indie developers and small SaaS businesses. Like Paddle, it handles all tax compliance globally, but with a simpler setup process and pricing model optimized for smaller businesses. It supports digital downloads, subscriptions, license key generation, and donation-style payments.

The platform provides a beautiful, customizable checkout overlay that handles payment collection, tax calculation, and receipt delivery. LemonSqueezy supports credit cards and PayPal, with automatic currency conversion for 30+ currencies. Built-in features include discount codes, affiliate programs, email marketing, and a customer portal for subscription management.

The @lemonsqueezy/lemonsqueezy.js SDK provides a typed API for managing products, variants, checkouts, subscriptions, and license keys. Webhooks deliver events for purchases, subscription changes, and license activations. License key validation enables software licensing with activation limits, expiration dates, and hardware fingerprinting. The platform is particularly popular with indie hackers, course creators, and desktop app developers.
