The short version

  • Each has a real cost: OutSystems application Objects grow with every screen, table and API an app gains, so a successful app that keeps adding features can push the account into AO overage charges that were not modelled at initial budget time.; 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.
  • They diverge on capability: OutSystems covers Visual application modelling, Temenos Transact covers Country model banks.
  • 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.

OutSystems

  • Application Objects grow with every screen, table and API an app gains, so a successful app that keeps adding features can push the account into AO overage charges that were not modelled at initial budget time.
  • Internal users are sold in packs of 100 and external users in packs of 10,000, so a company just over a pack boundary in either category pays for a full additional pack rather than a handful of extra seats.
  • Entry-level ODC pricing starts around 36,300 US dollars a year before any AO overage or extra user packs, which puts it out of reach for smaller teams evaluating low-code options.
  • Cloud infrastructure and hosting costs are frequently separate from the platform licence, so the all-in bill is higher than the headline subscription figure suggests.
  • Migrating a large application portfolio off OutSystems once built is difficult, since the generated code and platform-specific patterns are not designed for a clean export to standard frameworks.

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.

Answered from the vendors’ own pages

OutSystems: What is an Application Object?

A unit OutSystems uses to measure application complexity, counting elements such as screens, database tables and exposed APIs; more AOs mean a bigger licence requirement.

Temenos Transact: Is Transact the same as T24?

Yes. T24 was renamed Temenos Transact; older installations and much of the consultant population still use the T24 name.

OutSystems: Is there a free tier?

OutSystems has offered free or trial tiers historically for evaluation, but production use at any scale runs on paid ODC plans.

Temenos Transact: Can it run in the cloud?

Yes, it is offered on public cloud, though many existing installations remain on-premises and moving them is a project.

OutSystems: How does external user pricing work?

External users, typically customers or partners, are sold in packs of 10,000 at roughly a hundredth of the per-seat cost of internal (employee) user packs.

Temenos Transact: What drives the cost?

Licence scaled by size, annual maintenance as a percentage of licence, and implementation partner fees that usually exceed the software cost.
