Room For Improvement

GeneXus requires better front-end, training, security, integration, collaboration, market awareness, UI, code speed, cost, community, alerts, performance, and language support.
OutSystems needs to enhance performance, reduce costs, improve support, and refine integration, UI, documentation, and AI capabilities.
OutSystems does support tools to help categorize components across different layers, but enhancing features related to architecture would be beneficial for accommodating new changes more easily in our existing applications.

A couple of things which can be improved into OutSystems include the licensing cost, the vendor lock-in side, the learning curve, couple of integration aspects and customizations.

Internal System Coordinator at Red CEDIA
Offers a simplified architecture with outstanding integration capabilities
The integration capabilities of GeneXus are highly valuable for our organization. The metadata obtained within the logic of different systems is also vital. Due to the solution, our company team doesn't have to work with multiple languages and integrations can be made with C Sharp. JavaScript can also be used with GeneXus, the tool takes charge of all the rest and has a simple architecture. The solution can be used out of the box without facing any issues and nothing much needs to be done with frameworks. In our case we need to use Python with GeneXus, we use Ironpython to embed python code in C# .

OutSystems facilitates rapid application development and effective project management
What I find valuable about OutSystems is that it has a very good learning curve for developers. Within two weeks, we can gain knowledge in OutSystems, and it is very easy to learn. With my background being .NET, OutSystems is straightforward to learn, which is beneficial. Developing applications in OutSystems is good, and the flexibility allowed by OutSystems for application development is excellent compared to my experiences with other low-code technologies, where I've faced some challenges. The clean separation of concerns in the architecture provided by OutSystems is a key benefit compared to other platforms. OutSystems integrates with our existing tech infrastructure and provides flexible integration. If we want to integrate with third-party services, OutSystems has SOAP and RESTful services that allow us to consume external services, integrate with external databases such as SQL or Oracle, and includes integration studio for writing custom .NET code. After developing a .NET component, we can reference it in service studio, creating a reference file that makes integration easy. OutSystems officially supports various integrations and also includes an API discovery tool for consuming and exposing services, providing a lot of information about incoming URLs, similar to how we use Postman.
