Featured Reviews

Luis Gerardo Meneses Hernandez - PeerSpot reviewer
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.
Sukrut Joshi - PeerSpot reviewer
Enables users to develop applications quickly and has a responsive and helpful technical support team
The time to market is quite good. We can quickly develop an application using the tool. OutSystems is developed using .NET and Java. We can easily find technical resources who have worked on .NET and Java and leverage their previous knowledge to develop OutSystems applications. It can also be used for application development. If an end-user does not want to use the solution after two to three years, OutSystems sends the source code and the applications to the end-user. There is no dependency. It’s one of the major factors I found quite good in OutSystems.

Quotes from Members

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

Pros

"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."
"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."
"Speed of delivery: We were able to reduce development time by 30%."
"The solution is all-encompassing and very easy to use with its drag-and-drop feature."
"The most valuable features of OutSystems are the user interface, the flexibility to quickly integrate with almost anything in the system, and the ability to connect with databases."
"Refactoring with TrueChange is very simple."
"The visual program of OutSystems is one of the major advantages of this solution."
"I like the mobile features the most, and there are also various features around the portal we created that I enjoy."
"OutSystems is a robust and rapid application development platform with a less steep learning curve."
"OutSystems' best feature is that you can build tests with the flow, so even the tests are made in the PDD framework in a low-code way."
 

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."
"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 tool needs to improve the efficiency of its widgets."
"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 initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."
"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."
"OutSystems does not provide any native reporting resources. All reports must be created with other tools or as a webpage."
"In OutSystems, cloud management is an area of concern where improvements are required."
"The product's high price is an area of concern, where improvements are required."
 

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."
"The solution is expensive. The platform is not suitable for all of my clients. I work with labor unions and other smaller organizations that would not be able to afford the platform's current pricing model. It would be beneficial if there were a scaled-down version or a tiered pricing option that would allow me to build an app or a web app that is more cost-effective for my clients. Currently, the platform's pricing is too high for many of my clients, who would not be able to afford something in the $50,000 to $100,000 range."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"For one developer to use, the cost is around $5,000."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"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."
"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."
"There is a need to make yearly payments towards the licensing costs attached to OutSystems. It is an expensive product."
"Pricing could be a concern. You have to pay yearly, even after you have completed your development."
