Possible disadvantages of OutSystems

Cost
OutSystems can be expensive, especially for smaller businesses or startups due to its pricing structure, which may restrict its accessibility.
Learning Curve
Although it is a low-code platform, mastering OutSystems requires a certain amount of learning and adaptation, especially for developers used to traditional coding.
Vendor Lock-In
Applications built on OutSystems are tightly coupled with the platform, which can make it difficult to migrate to other solutions if needed.
Complex Custom Requirements
While OutSystems is highly flexible, certain complex custom functionalities might still require traditional coding or workarounds, which can increase development time.
Performance
For highly complex or performance-sensitive applications, the abstraction provided by a low-code platform like OutSystems can sometimes lead to suboptimal performance.
Limited Offline Capabilities
Offline capabilities are somewhat limited compared to fully native development options, potentially restricting the use cases for certain types of mobile applications.
Dependency on Proprietary Tools
Relying on OutSystems means depending on proprietary tools and services, which could be a disadvantage if the company decides to change its toolset or strategy.
