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.
Bireswar Das - PeerSpot reviewer
A low-code platform for the development of mobile and web enterprise applications
To illustrate a case, the customer initially had a private cloud, essentially a data center hosted within it. They needed a disaster recovery solution, which would involve using a public cloud. This situation led to some deployment challenges due to the hybrid nature of their setup. However, once we implemented the solution for them, they were extremely satisfied. The process was not only effective but also quite speedy. To be more precise, we completed it in around 100 days, even though they initially requested it to be done in four months. They were very pleased with the efficiency of the implementation.

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."
"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."
"The architecture of OutSystems is quite simple, and the features are similar to Mendix's. OutSystems has connectors for different enterprise apps and solid reporting capabilities. You can also integrate with any content management platform like SharePoint or Adobe Enterprise Manager, or something like that. You can also create and integrate workflows."
"The most valuable feature is Agile development. I love that you save a lot of time on development and can focus on logic and business requirements."
"Once built, web/mobile components can be reused in all new developments. In addition, the OutSystems Forge is very useful. We can exchange components and even already-built applications, reducing costs to build specific solutions."
"OutSystems is a hybrid framework and supports my mobile and web application development needs. This means I don't have to write separate code for mobile applications. It adapts the UI and functionality, whether I'm developing for web or mobile interfaces. All I need to do is provide the layout during development."
"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."
"The drag-and-drop feature is very valuable."
"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."
 

Cons

"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."
"I am trying to see how it can be integrated with the backend. That said, I haven't gotten there yet."
"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."
"The solution's testing framework needs to be improved, and the workflow should be slightly more mature."
"I have difficulty in using several new features. Some of the product's features are tricky to use as well."
"I would like to see OutSystems improve its integration capabilities, especially with emerging technologies like AI and GPT."
"The installation is a bit tedious."
"I think OutSystems needs to improve in many areas. First, sometimes Service Studio becomes really slow and even hangs for long periods. Also, if I have not published my module in some time, and some kind of Service Studio exception occurs, I lose my work."
"The PDD framework can't be used for the behavioral-driven development way of working."
 

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."
"There is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."
"It is very high price."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"For one developer to use, the cost is around $5,000."
"For a single application, it's too expensive."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"The tool’s licensing is based on the user’s usage."
"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."
