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

"This product is a powerful, cross-platform application development platform."
"Enables me to use the same web technology to develop cross-platform native apps. The cloud-based one-click app build system is a valuable feature as well."
"I found Axway Appcelerator packed with awesome features, that it was easy to learn and easy to build cross-platform."
"It is easy to create builds and distribution is very easy."
"One of the main advantages I look for with titanium is its cross platform development (iPhone, iPad, iPod, Android, Windows, Linux and OS X)."
"You can go huge - so it is definitely a scalable solution."
"The technical support is perfect."
"Overall, it's a very nice solution."
"Reduces the manual labor in compiling and deploying applications and generating procedural code (by reducing development bureaucracy/processes, resulting in real gains). The LifeTime Server approach, requiring just a few steps to publish applications in production environments, is fantastic."
"Let's assume a project in .NET, native .NET, or Java takes around 12 months. In OutSystems, we can build that application in four to five months."
"It is easy to use."
"We used almost all of the features, themes, styling guide, and approach components. They are useful in our applications."
"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."
 

Cons

"Unlike PhoneGap Titanium, this product relies heavily on the existing Android ADK or iOS SDKs."
"Titanium Studio, provided for development on titanium, happens to ignore changes while building and at times it stops printing console messages, so that every time you have to test your code, you have to clean your project."
"It would be awesome if they would work on improving the speed of the app building process."
"It has hung many times during login and use. Also, it needs a little enhancing for debugging for Android apps."
"Scalability is not so good if you have a complex UX."
"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."
"There's no exit strategy in OutSystems. If you want to leave it or want to go to another technology, you're kind of stuck, and it will cost you a huge investment to get rid of that."
"The integration Studio could be improved. It needs a tool in which we could develop C# code and then integrate into OutSystems. The application could have a better UI."
"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."
"The biggest challenge for us is the licensing model and the cost of OutSystems."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"I've read that where you have large deployments, OutSystems starts to crumble a bit."
 

Pricing and Cost Advice

Information not available
"OutSystems is a very expensive solution, and it has to be cheaper."
"OutSystems is expensive, and they changed the pricing model in the last couple of years. It's changing too much and it's becoming unstable. They are constantly shifting their prices based on users, courses, and other factors."
"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."
"OutSystems was open to a deal that worked for both sides."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"I would rate it five to six out of ten."
"It's not cheap. It's pretty expensive."
