The short version

  • Only Formance has a free tier, so it costs nothing to try first.
  • Each has a real cost: 10x Banking engagements are multi-year core replacement programmes with costs dominated by migration and integration, so the licence is a minority of what you actually spend.; 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.
  • They diverge on capability: 10x Banking covers SuperCore ledger, Formance covers Double-entry ledger.
  • 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.

10x Banking

  • Engagements are multi-year core replacement programmes with costs dominated by migration and integration, so the licence is a minority of what you actually spend.
  • The customer list is small and concentrated in large institutions, which makes reference checking and benchmarking difficult before committing.
  • It is a smaller vendor than Temenos or Finastra carrying a systemically important workload, and bank procurement teams treat that concentration as a genuine risk.
  • Product configuration replaces code but shifts complexity into configuration governance, which banks must staff and control just as carefully as software releases.
  • Value only appears after migration, so a programme cancelled or paused mid-transition leaves the bank running two cores and paying for both.

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.
