The short version

  • Only KeystoneJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fintecture coverage and merchant adoption are heavily French, so a European rollout means strong performance in one market and a thin experience in the rest.; KeystoneJS database support is limited to PostgreSQL, MySQL and SQLite
  • They diverge on capability: Fintecture covers Invoice payment links, KeystoneJS covers REST API.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fintecture

  • Coverage and merchant adoption are heavily French, so a European rollout means strong performance in one market and a thin experience in the rest.
  • Deferred and instalment payment relies on a financing partner that sets acceptance criteria, so your business customers can be declined for reasons you cannot see or influence.
  • As a payment initiator rather than an acquirer, Fintecture leaves refunds, disputes and settlement structure with the supplier, and there is no chargeback framework at all.
  • Business to business bank payments require the payer to authenticate with their bank, and corporate banking authentication with dual approval is materially clunkier than consumer app redirects, which hurts conversion on large invoices.
  • It is a smaller supplier than the pan European open banking firms, so bank API breakage outside France may take longer to fix and support depth is a legitimate procurement concern.

KeystoneJS

  • Database support is limited to PostgreSQL, MySQL and SQLite
  • Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
  • Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
  • Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

Answered from the vendors’ own pages

Fintecture: Is Fintecture aimed at retail checkout?

No. Its design centre is business to business invoice collection, where average values are high and reconciliation is the real problem.

KeystoneJS: Is KeystoneJS free?

Yes, KeystoneJS is free and open source with no licensing fees. Core platform has no lock-in and is contributed to by 250+ developers.

Fintecture: Who carries the risk on deferred payment?

A financing partner underwrites it, which means acceptance criteria and declines are set outside your control.

KeystoneJS: What are hosting costs for KeystoneJS?

KeystoneJS is self-hosted and deployment-agnostic. Hosting costs depend on your chosen deployment platform (Vercel, AWS, Heroku, etc.) and infrastructure, not KeystoneJS itself.

Source
Fintecture: Does it work outside France?

It operates in other European markets, but coverage and adoption are markedly weaker than in France.

KeystoneJS: Does KeystoneJS offer paid support?

Enterprise support with tailored options is available from Thinkmill, the company behind KeystoneJS. Pricing details available upon request.
