Senior Software developer at QV Systems
Rapid application development empowers big projects in months
The ability to quickly develop applications without needing to code a lot is very valuable. It is very quick to create a page, and one can use AI to speed up software development. It is easy to learn. In my company, we could develop a very big application in a couple of months.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Quick development and the connection with the database are the most valuable and useful features. It is also very stable, scalable, and easy to set up. Its support is also good."
"The support is great; whenever I encounter an issue and raise an SR to Oracle, I receive a fast response from their side."
"You don't have to know a lot of PL because it's built on PL/SQL. You don't need developers. You only need to design a good application that resolves a problem, or many problems, for companies and you're ready to go."
"Stability-wise, I rate the solution a ten out of ten."
"We set up the HTTP server and installed the Apex Xamarin DB using the Mark Hill SQL packages for an older version. That's the extent of our configuration."
"Efficient software delivery and a solution that works quickly."
"The product is easy to use."
"I like that Oracle Application Express (APEX) is powerful and attractive, allowing my organization to modernize forms within two months. I also found its PWA feature very powerful because you can produce substantial mobile applications."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"OutSystems is a robust and rapid application development platform with a less steep learning curve."
"For me, the most valuable feature is the flexibility the tools give us to change any customer requirements on the fly, when we are in a meeting. I also like how easy it is to deploy the code between environments and how easy it is to integrate OutSystems with other systems."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"There is literally a ton of stuff it can do. It's very flexible."
"The technical support is perfect."
"The scalability of OutSystems is very good, it scales automatically very useful for us."
"The most valuable feature of the solution is that it allows users to easily build applications."
 

Cons

"The solution has some stability problems that need to be resolved."
"Regarding features, the solution lacks the ability to integrate with different databases. Also, I feel that Oracle Application Express (APEX) is exclusively designed for other Oracle tools."
"The problem of sending emails arises when Oracle Application Express (APEX) is inside Oracle Cloud Infrastructure since it is a bit complicated or difficult to understand where to take care of the setup part to be able to just send out emails properly."
"Oracle Application Express would be improved if you could use it on a mobile platform."
"It can only be deployed on Oracle Database."
"When exporting, we can't export dynamic reports, only static reports. For example, when we want to export charts or tables it is only exported as a static report so we can't drop down on these reports; however, we can see this information when we are on the dashboard itself."
"The grid reports contain a lot of bugs."
"Connecting with Oracle and the relation with Oracle at the database as a procedure needs improvement."
"The asynchronous processing and multithreading tasks for which the current resources of the platform are very generic and not built for the end-user. Any asynchronous jobs have to be constructed with an end-user dashboard to allow inspection of the status of the activities."
"The latest version of the app generation tools could be more user-friendly."
"The tool's weakness is its focus on the solution only. Other than that, it's pretty easy to use for both technical and non-technical people. However, the tool lags in automation. For instance, we've used Python for scraping and other automated tasks. So, I believe automation is an area where it could improve."
"I like the OutSystems platform. I am working on integrating it with another platform using APIs, however, it has proven to be difficult. The main issue I am facing is obtaining authorization tokens as well as access and refresh tokens. It may be due to my lack of knowledge of APIs as it is new to me."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"The initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."
"There is room for improvement in technical support."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
 

Pricing and Cost Advice

"The solution is free with your Oracle license or database and that is a good value."
"The product is completely free of cost."
"It is expensive in comparison to other products."
"There is a trial version available that can be used free of charge."
"To my understanding, my organization is using the free version of Oracle Application Express (APEX), but I'm unsure because I haven't checked the pricing or licensing cost for it."
"When buying the data license, APEX is included."
"It's a free solution with no additional costs."
"The pricing is very good and less expensive than Mendix or OutSystems."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"It is too expensive for small companies."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"For one developer to use, the cost is around $5,000."
"I think the pricing for OutSystems is comparable with similar solutions. I would place it somewhere in the middle. We pay for the bundle and don't pay anything extra in terms of licensing and other fees."
"The tool’s licensing is based on the user’s usage."
"There are no additional costs with the standard license."
