Where each one falls short

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

Backendless

  • Free tier limited to 50 API requests per minute and 20 database tables
  • Smaller community and integration ecosystem compared to Firebase or AWS
  • Customization beyond codeless tools requires developer expertise
  • Limited documentation for advanced use cases and edge cases

Temenos Transact

  • The codebase originates in the 1990s, so banks on older releases face major upgrade programmes to reach current versions, and many defer them for years.
  • Total cost is dominated by implementation partner fees rather than licence, and those programmes routinely overrun their original estimates.
  • Product changes that cloud-native cores treat as configuration can require development work and a release cycle, which slows time to market for new products.
  • Heavy customisation is common and it makes every subsequent upgrade harder, creating a compounding cost that banks feel a decade after go-live.
  • Temenos has repeatedly restructured its product line and naming, so buyers must check carefully which components a proposal actually includes and which are separately licensed.
