  • They diverge on capability: OutSystems covers Visual application modelling, Zendesk covers Ticket management.

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.

Zendesk

  • AI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
  • Copilot and Contact Center features available as separate add-ons at £50+/agent/month
  • Advanced routing, workforce engagement, and approval workflows limited to Enterprise tier
  • Highest tier requires sales consultation and custom pricing

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.

Zendesk: What is included in the free trial?

You'll have access to all features on the Zendesk Customer Service Suite Professional plan for 14 days, with Copilot included by default.

Source
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.

Zendesk: How is Zendesk pricing calculated?

Base subscription pricing is determined by your selected plan tier and the number of agent seats needed. Additional costs include usage-based features like App Builder and Voice, plus optional add-ons.

Source
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.

Zendesk: What are the contract terms?

Zendesk subscriptions are month to month, annual, or multi-year. Annual billing typically costs less than monthly payments.
