What you gain

  • No 2.9% + $0.30 per-transaction fee eating into margins
  • Full control over payment flow UX without Stripe's iframe constraints
  • No vendor dependency for subscription lifecycle management
  • Self-hosted billing logic with direct bank/processor relationships

What you give up

  • No Stripe Billing with automatic proration, trials, and dunning
  • No Radar for ML-powered fraud detection across millions of merchants
  • No Stripe Connect for marketplace/platform payment splits
  • No 135+ currency and local payment method support out of the box

Switching Cost

Stripe's lock-in is the payment infrastructure, not the data. Customer records and subscription data export via API. But Stripe Billing's proration engine, Radar's fraud detection, and Connect's marketplace splits are deeply complex systems that took years to build. Simple one-time payments can move to any processor in a day. SaaS companies with complex subscription tiers, usage-based billing, and dunning workflows should budget 4-6 weeks. The hidden cost is PCI compliance: Stripe handles it for you, and going direct means your security requirements jump significantly.

What open source can't replace

Open source can do checkout, subscriptions, and basic card processing. It cannot do Stripe Radar (their fraud ML trained on billions of transactions), instant payouts, or the regulated money-movement pieces that require Stripe holding a license in 47 countries. If you process under $50k/mo and accept some manual fraud review, the OSS stack below works. Above that, you're paying Stripe for risk infrastructure, not code.

OSS covers

  • checkout flows
  • subscription billing
  • basic card processing

OSS does not cover

  • Stripe Radar fraud ML
  • instant payouts
  • regulated money movement in 47 countries
  • merchant of record

Building Blocks

Stripe is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
