  • They diverge on capability: Fastlane covers Screenshot automation, Formance covers Double-entry ledger.

Where each one falls short

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

Fastlane

  • Requires command-line and Ruby familiarity to configure and maintain Fastfiles.
  • No hosted UI or dashboard; it is a local/CI toolkit rather than a managed service.
  • Community-maintained plugins vary in quality and maintenance status.
  • No built-in analytics or crash reporting; it must be paired with other tools for those needs.

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.
