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

"I like the simplicity of making panels with Flutter."
"The most valuable features of FlutterFlow are the integrations and workflows."
"It allows you to create fragments that look good and work on both mobile and web environments."
"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."
"Our previous solution had other overheads such as release management, version management, code management, monitoring, etc., all of which are built-in with OutSystems."
"OutSystems is a robust and rapid application development platform with a less steep learning curve."
"Comparatively, I'm able to see OutSystems is very easy to maintain and easily fulfills the business requirements."
"In terms of user support and community engagement, I rate the tool a ten out of ten."
"I really like the one-click publish feature in OutSystems. In other development tools/languages, it's not as easy. I also like how easily I can manage all my projects in one place."
"You can go huge - so it is definitely a scalable solution."
"The solution is stable and doesn't require many server resources, so I don't think there are stability issues."
"The product is mostly stable."
 

Cons

"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"There is room for improvement in advanced functionality so it could cater to more complex app development needs."
"Scaling depends on project requirements."
"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."
"The cons involve delays in project timelines primarily due to the time taken in requirements refinement and challenges faced when adding new features, making it somewhat complex to manage and maintain applications as they grow in scale."
"The small-scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost."
"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."
"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."
"The technical support is not very good but I still give it a six out of 10."
"The solution is costly."
"Writing custom code still needs to be done via Integration Studio. This might have been added to the IDE."
"There is room for improvement in technical support."
 

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."
"As for licensing costs, I'm not directly involved in that aspect."
"I would rate it five to six out of ten."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"It is very high price."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"It is still very expensive, so small companies can’t generally afford it... Still, the time saving on development and delivery is worth the value."
"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."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
