Strengths & Weaknesses
Polar
20% cheaper than competitors at 4% + 40¢ per transaction with no monthly minimums or hidden fees
Open-source (Apache 2.0) with full code transparency and no vendor lock-in
Exceptional developer experience with TypeScript SDK, API-first design, and 6-line integration
Automated entitlements for license keys, GitHub access, Discord roles, and file delivery
Young platform (founded 2023) with less operational maturity than established competitors
Additional fees: +0.5% for subscriptions and +1.5% for international card payments
Limited third-party integrations and marketing tools compared to Lemon Squeezy or Paddle
Stripe
Best-in-class API documentation and developer experience with SDKs in 10+ languages, extensive code examples, and fast integration times
Comprehensive fraud prevention with Stripe Radar using machine learning to block fraudulent transactions before they happen, included at no extra cost for standard pricing
Massive ecosystem with 1,000+ pre-built integrations and a thriving marketplace of apps and extensions
No monthly fees, setup costs, or hidden charges—purely pay-as-you-go pricing that scales with your business
Higher per-transaction fees (2.9% + $0.30) compared to interchange-plus processors, which can significantly impact margins for high-volume businesses
Account holds and sudden freezes can occur without warning, particularly for new accounts or those in high-risk industries, sometimes locking funds for 90+ days
No built-in PayPal support—businesses must integrate PayPal separately if they want to offer it as a payment option
