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."
"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."
"It is very stable."
"The most valuable features of OutSystems are the user-friendly platform. The drag-and-drop feature is great. I have used other rapid application development tools before, but they were not as advanced as OutSystems. With the previous tools, I had to manually build certain features, but OutSystems does it automatically."
"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 product is mostly stable."
"There is literally a ton of stuff it can do. It's very flexible."
"The technical support is perfect."
"Integrations with external systems with SOAP and REST are easy to implement off-the-shelf, but a developer can always implement specific libraries for other integrations."
 

Cons

"Scaling depends on project requirements."
"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"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."
"It is hard to find the logic in OutSystems. From an improvement perspective, I want to be able to properly use logic in OutSystems."
"I would like to see improvements in versioning. It can be challenging to keep track of what changes should be committed, especially when many developers are working in one environment."
"The latest version of the app generation tools could be more user-friendly."
"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"The prices should be lower. It is a little bit too high for a small market."
"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."
"While I can't speak to the market impact, as a developer, I've seen significant reductions in development time across different versions of our applications. One area for improvement would be the UI controls in Service Studio. Sometimes, controls don't appear in the IDE, requiring us to check them in the web browser instead. Overall, our experience with OutSystems has been positive, though improvements in UI development would be welcomed."
"We'd like OutSystems to add stronger workflow-based automation similar to what Appian offers. It needs more workflow modeling and RPA features."
 

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."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"It's not cheap. It's pretty 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."
"As for licensing costs, I'm not directly involved in that aspect."
"The tool’s licensing is based on the user’s usage."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"OutSystems was open to a deal that worked for both sides."
