Adyen bundles payments and financial products behind one API, with pricing and integration aimed at scale. Developers on Reddit say it can require high transaction volume and more setup than simpler gateways. These alternatives are not all like-for-like: some focus on checkout, while others handle payouts, tax workflows or fiat ramps. Compare supported markets, payment methods, SDK coverage, total fees and recurring-payment migration before routing production traffic.
01Why people leave Adyen
Volume requirements
A Reddit commenter says Adyen requires much higher volume; another recommends it mainly when transaction volume reaches enterprise scale.
Integration overhead
Developers on Reddit report fewer tutorials for Vue and say Adyen can take more setup than a simpler checkout.
Switching costs
A Reddit thread warns that recurring payments make switching harder; provider and payment-method differences need migration planning.
02The alternatives, ranked by fit
- Multi-market checkout
Checkout.comCheckout.comCheckout.com offers a unified payments API and multiple checkout options, which may suit teams comparing payment flows across markets. Its pricing is opaque, and marketplace coverage needs investigation. The pricing page lists a free plan, but that does not establish transaction costs at your volume. Confirm API and SDK coverage, marketplace support and commercial terms before migrating.
Trade-off: Pricing and marketplace fit need confirmation.
6.5/10from
Freefree plan - Global SaaS sales
PaddlePaddlePaddle is aimed at digital products and SaaS teams that want a provider to handle global payment operations, tax and compliance, plus subscription payment recovery. The listed starting price is $0, but confirm how fees work at your sales volume. Check its integrations against your stack and plan how to export data and move customers if you leave.
Trade-off: You depend on a provider for global operations and need an exit plan.
6.0/10from
Freefree plan - International payouts
DotsDotsDots combines global payouts, payee onboarding and tax workflows behind a hosted API. It fits platforms paying recipients internationally that want those operations together rather than only a card-acceptance replacement. The listed starting price is $19; confirm transaction and payout fees, supported markets and API details. This is a payout-focused option, not a like-for-like checkout substitute.
Trade-off: Payout workflows, not general checkout, are its focus.
7.0/10from
$19/mo - Fiat ramps
OnramperOnramperOnramper provides one integration for multiple fiat ramps, including offramps and swaps, for apps serving multiple countries. It may reduce the number of provider integrations your team maintains for those flows. The listed starting price is $150, with provider-level fees to weigh separately. Confirm supported countries, provider coverage and the integration details your application needs.
Trade-off: Provider-level fees add to the plan cost.
7.0/10from
$150/mo - High-volume payouts
CheckbookCheckbookCheckbook is built for frequent disbursements, branded marketplace payment flows and multiple payout methods. Its marketplace controls may fit platforms whose main need is sending money rather than accepting checkout payments. The listed starting price is $2,000, and transaction rates need confirmation. Compare that entry cost with your payout volume and ask about API coverage before committing.
Trade-off: The published entry price is high; transaction rates need confirmation.
6.1/10from
$2,000/mo - Cross-border payments
ThunesThunesThunes supports cross-border payments through an API or Swift, with local payment methods and liquidity management in its target use cases. It may fit businesses paying recipients across markets rather than teams replacing a card checkout flow. Pricing is not listed; confirm commercial terms, API access, supported routes and settlement details before building around it.
Trade-off: Commercial terms need confirmation, and it is payout-oriented.
6.3/10from
Custom - Multichannel acceptance
CardPointeCardPointeCardPointe offers a hosted payment stack for merchants and software providers embedding payments, including teams using its retail terminals. It is worth comparing if your requirements span more than online checkout. Pricing is quote-only, and merchant reports call for caution. Confirm API and SDK coverage, terminal compatibility, processing costs and migration support with the vendor.
Trade-off: Quote-only pricing and merchant reports warrant diligence.

Questions people ask
Which Adyen alternative is cheapest?
There is no like-for-like answer from starting prices alone. The listed prices range from $0 for Paddle to $2,000 for Checkbook, while Checkout.com lists a free plan. These are not comparable processing rates. Ask each vendor for transaction, payout and provider fees based on your payment mix and volume.
Are any of these alternatives open source or self-hosted?
Do not assume an option is open source or self-hosted without a published licence and deployment documentation. Ask vendors about hosting, data export and what happens to payment records if you leave. The options listed here are commercial payment or payout services, not an identified open-source replacement.
How hard is it to migrate recurring payments from Adyen?
Plan recurring-payment migration separately from one-time checkout. A Reddit commenter warns that switching gets harder once recurring payments are involved. Before choosing a replacement, ask both providers what customer and payment data can be transferred, which payment methods remain supported and what work your team must handle.
