The short version

  • Only Formance has a free tier, so it costs nothing to try first.
  • Each has a real cost: Formance formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.; Tink visa owns Tink, and pay-by-bank exists to move payments off card rails, so the roadmap and pricing of the product you are using to reduce interchange are set by the company that earns the interchange.
  • They diverge on capability: Formance covers Double-entry ledger, Tink covers Account data access.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Formance

  • Formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.
  • Numscript is a domain-specific language your team must learn, and while it makes complex splits expressible it also means transaction logic sits outside the languages your engineers already debug well.
  • Self-hosting a ledger that must never lose or duplicate a transaction is a serious operational commitment covering backups, upgrades and Postgres tuning, which is real cost the zero licence fee hides.
  • Enterprise pricing is not published, so the difference between the free path and the supported path cannot be evaluated without a sales conversation.
  • The company is much smaller than the incumbent alternatives, and while the MIT licence protects the code it does not protect the roadmap, so features on the hosted side may arrive slowly or change direction.

Tink

  • Visa owns Tink, and pay-by-bank exists to move payments off card rails, so the roadmap and pricing of the product you are using to reduce interchange are set by the company that earns the interchange.
  • Coverage is Europe only, so a product serving both European and United States users runs a second aggregator with a different data model and a separate contract.
  • PSD2 connection quality varies sharply by bank, and headline connection counts hide wide differences in success rate, consent lifetime and re-authentication frequency that determine what users actually experience.
  • Consent under PSD2 expires and requires periodic re-authentication, so any product depending on continuous data access has a recurring user friction it cannot design away, and drop-off at re-consent is a real product problem.
  • Pricing is quoted with data access and payment initiation priced separately, and there is no published rate card, so small merchants cannot compare pay-by-bank economics against card acceptance without a sales process.

Answered from the vendors’ own pages

Formance: Is Formance really open source?

Yes. The core ledger is MIT licensed with full source access and no deployment restrictions.

Tink: Who owns Tink?

Visa, since 2022. That is directly relevant if you are adopting pay-by-bank specifically to reduce card costs.

Formance: Does Formance move money?

No. It records and orchestrates movements; the actual payments happen at a PSP or bank you connect.

Tink: Do I need my own PSD2 licence?

No. Tink holds AIS and PIS licences from the Swedish FSA passported across the EEA, and customers can operate as its agent rather than obtaining their own authorisation.

Formance: What does the enterprise version cost?

Not published. It is an annual subscription quoted per customer.

Tink: Does Tink cover the United States?

No. It is a European platform. US coverage requires a separate provider.

Formance: Do I have to use Numscript?

Yes for anything beyond the simplest transfers. It is how multi-party transactions are expressed atomically.

Tink: How reliable are the bank connections?

It varies by institution far more than the headline count of roughly 6,000 connections suggests. Ask for per market and per bank success rates and consent lifetimes for the banks your users actually hold accounts with.
