The short version

  • Only Drupal has a free tier, so it costs nothing to try first.
  • Each has a real cost: Drupal steep learning curve: concepts that are implicit in WordPress are explicit and must be configured; 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.
  • They diverge on capability: Drupal covers Structured content modelling, OutSystems covers Visual application modelling.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Drupal

  • Government and university sites with complex content models and strict permissionsnot OutSystems
  • Multilingual sites where translation is structural rather than a pluginnot OutSystems
  • Publishers needing custom content types and editorial workflownot OutSystems

OutSystems

  • An enterprise replacing custom .NET or Java application development with a governed low-code platform at scalenot Drupal
  • A company building customer-facing portals where the external-user pricing tier (packs of 10,000) is materially cheaper than licensing customers as internal usersnot Drupal
  • An IT department that wants generated, inspectable code rather than a proprietary black-box runtimenot Drupal
  • An organisation with a large existing application portfolio needing centralised governance across many apps built by different teamsnot Drupal

Where each one falls short

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

Drupal

  • Steep learning curve: concepts that are implicit in WordPress are explicit and must be configured
  • Smaller developer pool than WordPress, and correspondingly higher build costs
  • Major version upgrades have historically been substantial projects, not routine updates
  • Considerably more machinery than a straightforward marketing site needs

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.

Answered from the vendors’ own pages

Drupal: Is Drupal free?

Yes, open source under the GPL. Costs are hosting, development and any commercial modules.

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.

Drupal: Drupal or WordPress?

WordPress is faster to launch, cheaper to staff and has a much larger plugin ecosystem. Drupal is stronger when the content model is genuinely complex and permissions are strict, which is why institutions favour it.

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.

Drupal: Why is Drupal common in government and universities?

Structured content modelling, granular access control and multilingual support are core rather than bolted on, and those are exactly the requirements those sectors have.

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.
