Room For Improvement

Leverage rapid prototype development for application building
The pricing structure needs improvement since it uses cloud billing. We do not know how the pricing is calculated as it is all on the cloud. The concept that the more you use, the more you have to pay could have been much better. They could have implemented credits based on usage so that users would be able to easily calculate the pricing and provide it to customers. I am the co-founder and CTO of the company called Aiwox (A I W O O X). We have numerous projects for mobile application development, and we have shifted from Google Firebase to Supabase because there is a fixed price for Supabase. Supabase is built on top of AWS, and it provides a very good pricing model. Some of the credits are free, and once you reach a certain limit, you know the charges. The second improvement area is related to SQL. They provide the real-time database, which is very good, and they have gradually started including PostgreSQL, which is a relational database, but it is not production-ready yet. I may be incorrect; perhaps they have released something new, but PostgreSQL database real-time database remains a challenge with Google Firebase.

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.
