Software developer at Apps2Go TECH

Creates versatile applications seamlessly across platforms

I like the simplicity of making panels with Flutter. It is easy to use when you understand the code, know how to use Docs, and understand the components of Flutter. It allows you to create fragments that look good and work on both mobile and web environments. Additionally, it works for both PC and iOS devices.

Rapid delivery has transformed complex enterprise apps and supports faster cross-domain projects

Every platform or low-code platform tool is quite good in its own area, but there is always space to groom or enhance or improve. The same is with OutSystems as well. A couple of things from the integration point of view can be enhanced. If your application or the enterprise organization is tackling a huge data application where you have bulk amounts of data, it becomes a challenge for all the technologies and the same with OutSystems. You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced. Data handling and huge data handling is a kind of challenge you may need to face. Then we have some vendor lock-in. If you are trying to migrate your application from OutSystems, then you probably get into this vendor lock-in system. Some organization may face challenges if some organization is on a small scale size. The small scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost. Apart from that, OutSystems really plays well, and it needs a learning curve. If a traditional application or programming is there which your developers are skilled into and they are directly deployed into OutSystems, it may take some significant amount of time for them to get comfortable with OutSystems. There is a learning curve. OutSystems community is already in place, but it can more be enhanced regarding some aspects. They did organize lots of bootcamps and other user groups as well, but those can also be improved from the documentation point of view and having some integration guidebook as well. 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.

Quotes from Members

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

Pros

"FlutterFlow offers a lot, but one feature that really helps me is the debugging features that allow me to test everything on the spot. This is really helpful."

"It allows you to create fragments that look good and work on both mobile and web environments."

"I like the simplicity of making panels with Flutter."

"The most valuable features of FlutterFlow are the integrations and workflows."

"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."

"Refactoring with TrueChange is very simple."

"OutSystems is a low-code solution. Most features are like drag-and-drop, so it's pretty easy to work. Thus it helps the organization by saving time for developers."

"The visual program of OutSystems is one of the major advantages of this solution."

"OutSystems' low-cost approach has positively impacted our productivity, because we were able to develop faster with OutSystems, enabling us to implement many changes during our sprint."

"OutSystems is a robust and rapid application development platform with a less steep learning curve."

"We've used features like batch processing timers, components, and integrations with other systems like SAP, which have accelerated our development process.In terms of productivity, we've seen a 30 percent reduction in screen design time and an additional 10 percent improvement when implementing client requirements. OutSystems' integration capabilities have significantly enhanced our app's functionality, making it quicker and easier to connect with other systems."

"The most important features of this tool are its visual modeling capabilities and drag and drop functionality. You can see what you are coding which makes it easy to understand and maintain. They have also created a big revolution in digital transformation by introducing native mobile app development under the same IDE."

More OutSystems pros

Cons

"The UI components could be more standardized. Sometimes, for certain properties, I have to search more than I do with other platforms. With other platforms, once you know one, you know all. But with FlutterFlow, sometimes you have to look around for what you need."

"There is room for improvement in advanced functionality so it could cater to more complex app development needs."

"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."

"Scaling depends on project requirements."

"Currently, in mobile applications, we don't have push notifications."

"The largest obstacle currently associated with OutSystems is its high cost and limited availability of skilled personnel. Despite being a rapid application development platform, having a highly skilled individual familiar with the platform can be much more beneficial than an inexperienced individual. Because there is a shortage of people with the necessary OutSystems skills, utilizing the platform can become expensive. This makes little sense, considering that a rapid application development platform should be accessible to the average person. However, having a highly skilled individual can greatly increase productivity, making the cost worthwhile."

"The PDD framework can't be used for the behavioral-driven development way of working."

"The tool needs to improve the efficiency of its widgets."

"The integration points need to be increased. People have also started to adopt this solution for their regular needs. That means it's not only the big enterprises that are adopting this solution. There are also small and medium enterprises that are adopting it. I've read that where you have large deployments, OutSystems starts to crumble a bit. That is the idea that no customer would know at the beginning and would also not like to hit the wall there. When it is on the client, there are a lot of applications already on low-code, and then suddenly you realize that you want to do some big applications, and you face hurdles. This is the general feedback for all such platforms."

"The resource availability needs to be increased."

"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."

"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."

Pricing and Cost Advice

"I would rate the licensing costs a three out of ten, with ten being expensive and one being cheap. Currently, I use the free version."

"I would rate it five to six out of ten."

"OutSystems is a very expensive solution, and it has to be cheaper."

"The product is expensive and I would rate its pricing a seven out of ten. You need to pay a yearly subscription to use the product."

"It is not an expensive product, especially if you have access to more features and deal with more projects."

"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."

"For a single application, it's too expensive."

"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 solution is expensive."
