The short version

  • Only Bubble has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bubble apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown.; 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: Bubble covers Visual app editor, OutSystems covers Visual application modelling.
  • 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.

Bubble

  • Apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown.
  • Complex apps can hit performance limits compared to hand-coded applications as data and workflow complexity grows.
  • The visual workflow editor has a steep learning curve for genuinely complex business logic.
  • Free tier cannot host apps on a custom domain, limiting it to prototyping rather than production launches.

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

Bubble: Does Bubble publish pricing information on their main website?

Bubble's pricing details are not available on the main homepage. Detailed pricing information would need to be found on their dedicated pricing page or terms of service.

Source
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.
