The short version

  • Only Tray.io has a free tier, so it costs nothing to try first.
  • 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.; Tray.io now rebranded Tray.ai; pricing page names three tiers, Pro (3 workspaces, 7 day insights), Team (20 workspaces, 30 day insights) and Enterprise (unlimited workspaces, 180 day insights, SSO, HIPAA), but publishes no figures and requires a demo or sales call for a quote
  • They diverge on capability: OutSystems covers Visual application modelling, Tray.io covers Low-code workflow builder.
  • 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.

Tray.io

  • Now rebranded Tray.ai; pricing page names three tiers, Pro (3 workspaces, 7 day insights), Team (20 workspaces, 30 day insights) and Enterprise (unlimited workspaces, 180 day insights, SSO, HIPAA), but publishes no figures and requires a demo or sales call for a quote

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.

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.

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.
