Polar is a payment and subscription billing platform for developers that operates as a Merchant of Record (MoR), taking on tax handling and payment liability on behalf of the seller. It offers digital products, SaaS subscriptions, usage-based billing, and benefit delivery features such as license keys and file downloads, and it runs on top of Stripe. It differs from other MoR services such as Lemon Squeezy or Paddle in that it is an open-source project with public code.
