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.; Vodeno its actual regulatory backing differs by geography, Aion Bank in continental Europe versus NatWest in the UK, so a customer must understand which entity and licence they are actually contracting under rather than assuming one uniform Vodeno product.
  • They diverge on capability: Formance covers Double-entry ledger, Vodeno covers Core banking infrastructure.
  • 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.

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.

Vodeno

  • Its actual regulatory backing differs by geography, Aion Bank in continental Europe versus NatWest in the UK, so a customer must understand which entity and licence they are actually contracting under rather than assuming one uniform Vodeno product.
  • Pricing is entirely unpublished across both the European and UK businesses.
  • The scale of NatWest's investment (up to roughly £120 million) signals a business still working toward profitability, with NatWest itself targeting breakeven within five years of the venture launching, which is a meaningful timeline risk for a customer building long-term infrastructure dependency on it.
  • As banking-as-a-service infrastructure, any customer remains dependent on Vodeno's underlying bank partner maintaining its own licence and risk appetite, which is a layer of dependency beyond Vodeno's own commercial terms.
  • Product scope, such as lending and BNPL availability, may differ between the UK and European entities, so a company operating in both markets should not assume identical capability across the two.
