Hidden Costs Breakdown

1

Application Objects (AO) Complexity Fees

high addon

OutSystems charges based on application complexity measured in Application Objects (AOs), in addition to per-user fees. As your application grows in features and functionality, AO count increases, driving up costs significantly.

reddit · 2025-04-30

Outsystems is expensive. You pay per user + app complexity (they call it application objects)

reddit · 2025-04-21

1000 internal Users and 150 AOs is 75.000€

2

Mandatory Annual Renewal with No Exit

critical compliance

All applications require ongoing annual license payments to remain operational. There is no perpetual licensing option, and stopping payments means your applications terminate. Migration away requires complete rewrites due to platform dependencies.

reddit · 2019-07-27

You literally pay for everything every year unless you want your apps to terminate. There is no exit strategy other than to rewrite the applications from scratch due to dependencies.

Once you are in the door, it's a pricing trap.

3

Bug Maintenance Staffing

high support

Applications built on OutSystems require dedicated FTEs to manage significantly higher bug backlogs compared to traditional development. Users report needing one to two additional full-time employees per application just to handle ongoing bugs and issues.

reddit · 2019-07-27

Expect your backlog of bugs to be significantly higher than non-low-code environments. For every application you add, expect to add one or two FTEs to work the bugs.

4

Per-User Scaling Costs

high overage

Pricing increases with every additional user, making it expensive to scale. Large enterprises with 1,000+ users face substantial annual costs even for mid-tier application complexity.

reddit · 2025-04-21

1000 internal Users and 150 AOs is 75.000€

reddit · 2021-01-27

Their lowest pricing tier will cost you US$2000 per month ++

Reported Jan 2021; current paid plans are quote-based.

5

Add-on Costs Beyond the Base Subscription

medium addon

Add-ons are quoted separately on top of the Agentic Systems Platform subscription, for example 24x7 support (the base includes 8x5) and a 99.95% uptime upgrade (the base is 99.5%). Users report that many capabilities require additional payment beyond the entry package.

Once you go beyond the basic package, you pay a lot of money for everything.
