Choosing a payment API is one of the highest-leverage technical decisions a software company makes — it determines time-to-revenue, take rate at scale, global expansion cost, and how much engineering time goes to compliance versus product. We surveyed 218 GitHub-verified developers running payment APIs in production across SaaS, marketplaces, B2B, and consumer products. The right answer depends primarily on company stage and global complexity: indies and early-stage win with Stripe or merchant-of-record platforms (Paddle, LemonSqueezy); enterprises and high-volume merchants flip to Adyen for unit economics; specialty products go specialty.

Stripe remains the default payment API in 2026 because the developer-experience gap is real and gets larger when you account for the supporting ecosystem (Tax, Connect, Atlas, Issuing, Billing, Radar). Indies report shipping payments in 90 minutes. Enterprises report Stripe-trained engineers being available in every hiring market. The 2.9% + $0.30 take rate is real and compounds at scale, but for most companies the developer-velocity and time-to-revenue advantage dominates the percentage-cost analysis for the first $5-10M ARR.
Best for
SaaS, marketplaces, anyone where developer velocity matters more than 50 bps savings
Where it falls short
Percentage fees compound — at $10M+ ARR migrating to Adyen or MoR can save real money.
Paddle as merchant of record (MoR) handles sales tax, VAT, GST, and compliance globally. For SaaS selling to customers in 30+ countries, the alternative is registering for tax in every jurisdiction. The 5% take rate is higher than Stripe but tax-handling savings typically dominate until $3-5M ARR. The 2024-2026 Paddle Billing platform polished the subscription primitives to be genuinely competitive with Stripe Billing.
Best for
Global SaaS up to $5M ARR, indie products with EU/UK customer base, anyone who hates tax registration
Where it falls short
Take rate flips above $3-5M ARR. Customer email comes from Paddle domain, not yours.
Adyen is the enterprise payment platform. Below 1M GMV the DX gap with Stripe is decisive; above $5M GMV the interchange++ pricing model and native local-payment-method coverage typically save 50-90 bps a year. The unified online + in-store + risk platform matters for omnichannel retailers. Onboarding requires a sales call (not self-serve), which is the right model for the customer profile.
Best for
High-volume merchants ($5M+ GMV), omnichannel retail, EU + APAC heavy revenue
Where it falls short
DX trails Stripe. Onboarding via sales call. Smaller community for troubleshooting.
LemonSqueezy is the merchant-of-record platform optimized for digital products — software licenses, downloadable goods, course sales. The license-key API is the killer feature for software products. Stripe acquired LemonSqueezy in 2024 but the brand and product continue as separate offerings. Take rate matches Paddle (5%). Best fit: solo developers and small teams selling digital products who want zero tax overhead.
Best for
Software products with license keys, course creators, indie digital-goods sellers
Where it falls short
Stripe acquisition introduces long-term product-direction uncertainty. B2B invoicing less mature than Paddle.
Frequently Asked
Stripe vs Paddle — when does the math flip?
Roughly $3-5M ARR for global-customer SaaS. Below that, Paddle saves more in operational tax-handling than the 2.1-percentage-point pricing premium costs. Above that, Stripe + Avalara + part-time tax accountant becomes cheaper than Paddle 5%. The transition is gradual — most teams make the migration around $5M ARR.
Is Adyen worth it for a sub-$1M company?
No. The Adyen DX cost (more wrapper code, slower onboarding, less community) is real and at $1M GMV the percentage savings are not material yet. Stripe until you cross the volume threshold where Adyen interchange++ saves 50+ bps. That threshold is typically $5M+ GMV.
What about Square or PayPal?
Square is excellent for in-person retail with a software layer (POS, hardware). PayPal is excellent for cross-border consumer payments where buyers want PayPal-balance-paid checkout. Both are specialty. For most software products neither competes with Stripe on developer experience.
Are there alternatives for crypto / blockchain?
Coinbase Commerce, Wyre, Circle and Stripe Crypto all exist. For most products in 2026 crypto payments remain a small percentage of revenue and the operational overhead of supporting them is real. Default to fiat unless your product is crypto-native.
How do I evaluate payment API reliability before committing?
Three signals: (1) Read the recent status page — look at incident frequency and time-to-resolution in the last 6 months. (2) Search GitHub for "rate limit" + the API name to find real teams reporting issues. (3) Ask the vendor for their 90-day uptime numbers in writing. Stripe and Adyen publish theirs; smaller players sometimes do not.
What about indie-first alternatives like Polar or DodoPayments?
Newer indie-focused MoR alternatives exist. The reviewer cohort for them is currently below our 5-reviewer threshold for inclusion. We will rank them as cohort grows.
