The short answer
Polar vs Lemon Squeezy compares two merchants of record for digital products. As of October 2026, Polar's free Starter plan charges 5% + 50¢ per transaction, and paid plans lower that rate in exchange for a monthly fee (down to 3.4% + 30¢ on the $400/month Scale plan), with +1.5% for non-US cards. Lemon Squeezy charges 5% + 50¢ plus surcharges for international, PayPal, and subscription payments. Polar is open source under Apache 2.0, emphasizes usage-based billing and developer benefits such as GitHub and Discord access, and pays out through Stripe on request; Lemon Squeezy pays out twice a month and is moving toward Stripe Managed Payments after its 2024 acquisition by Stripe.

When Polar fits
Polar fits developers and AI or SaaS companies that want usage-based billing, automated delivery of license keys, GitHub repository access, or Discord roles, and an open-source codebase. Its plan tiers can lower per-transaction cost once revenue is steady; Polar's own breakeven figures put the Pro plan ahead of Starter at roughly $1,379 a month in sales. New organizations should note the 7-day settlement delay Polar applies to organizations created on or after May 12, 2026.
When Lemon Squeezy fits
Lemon Squeezy fits sellers who want a simple flat fee with no monthly plan, automatic twice-monthly payouts, and built-in affiliate and email tools for digital products. Its long-term direction is tied to Stripe Managed Payments, so check the company's 2026 update before choosing it for a new product.
Publishing revenue from either platform
RevenueBug supports both. Polar connects with an organization access token with organization, order, and refund read scopes; RevenueBug imports orders, refunds, and lost-dispute adjustments for the whole organization, so revenue from every product in it is aggregated. Lemon Squeezy connects with a full-access API key used only for read requests, scoped to a store you select, and its adapter cannot classify disputes. RevenueBug's headline figure is trailing 30-day revenue calculated before provider fees, so a provider's fee level changes what you keep, not the revenue shown on your profile.
