Dansteve Adekanbi - PeerSpot reviewer
Senior Frontend Developer Consultant at Modus Create
Great user acceptance and reliability, multiple teams not required, with prompt customer service
As a developer, I would say one of the improvements is more plugins. More plugins give you the ability to do more interactions with the framework over the library. As a user, I would say more flexibility in terms of look and feel. So far Ionic is very fluid. You might not really know, it is web-based technology. I know recently it has gone through a lot of updates, but it can also be improved and become stronger. Ionic allows you to get the best customization ever, but there is nothing like having more. The more customization you get, the easier it is for you to be able to build more quality apps.
Mitchel Mol BGS - PeerSpot reviewer
CTO at Blue Green Solutions
Has improved development quality and speed but has introduced persistent IDE slowdowns
In recent years, the IDE has been more buggy and slower, and although there have been more features added, I would like to see more stability, as some areas that used to work for a fairly long time are now slower in my development, which feels like a step back. I choose a seven mainly due to the issues we've faced with slowdowns and bugs during development, while runtime has been very stable, and the overall output on Mendix platform is still good; there is definitely some room for improvement, and I would probably have given it an eight or even a nine if those issues weren't hurting my developer output for the past few years. Overall, Mendix platform is stable, but the IDE could be better.
Aditya Bhatt - PeerSpot reviewer
Senior Technical Lead at a pharma/biotech company with 1,001-5,000 employees
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

"Because it's a hybrid mobile app framework, it is easy for us to develop iOS as well as Android apps for our customers with the same resource skills. We didn't have to have separate iOS teams and Android teams to build the apps. We still have to use the Apple Xcode for iOS, but the main development happens with JavaScript, HTML, and CSS. We don't have to write separate code bases in scripts for iOS and Android. We create apps using web-based technology."
"It's very flexible for UI development."
"The solution is secure, reliable, and packed with features so we can easily implement apps even in the most complex situations."
"Ionic is easy to upgrade and is helpful for design purposes, it also is quite common and easy to use, it is a very reliable application, it's easy to write on and print, and the UI is easy to use as well."
"Ionic is good for beginners as you don't need to understand advanced coding languages to start creating basic mobile applications."
"For a web developer who experiences web development like HTML, CSS, bootstrap, or any JavaScript framework, Ionic is used and it is great for those developers to develop mobile applications for Android, iOS, and PWA."
"Ionic is the best solution I have used of its kind."
"I believe it's worth learning this framework because, from what I've seen so far, I think it's a very good solution for hybrid mobile application development."
"The features that I have found most valuable with Mendix are its business process management and its minimal low code, both from an interface perspective and from a process perspective."
"The software is mainly designed and built by business engineers instead of software engineers, which leads to an immediate fit between delivered software and what the users really want."
"Mendix is a good option for people looking for fast deployment and multiple device support with single code."
"Overall the platform is really good."
"The best features Mendix offers in my experience include its readiness to go to market, which reduces the effort and time consumed in developing an application end-to-end."
"Mendix has made a great deal of effort to provide its developers a healthy, modern environment for developing."
"Excellent support is offered for Mendix"
"In short, Mendix has improved our ability to delight our customers."
"Some systems have over 1,000 end users; it's very stable for heavy duty operation."
"It is a stable solution."
"Comparatively, as a low-code kind of platform, OutSystems is the most intuitive to use, but if you have an experienced programmer in Java and .NET like myself, then the other platform is probably a bit more flexible."
"We find in OutSystems a great platform that enables extraction of data from multiple sources, and working with business logic to access essential information and produce process-automation at the highest level."
"The most valuable feature of OutSystems is the drag and drop and toolchains in the small AI developing environment. Additionally, the documentation is helpful."
"Their out-of-the-box UI is quite good."
"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."
"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."
 

Cons

"It would be better if it had a speed niche system. There are a lot of things we need that weren't in the latest version. But I think they will be adding something."
"There could be better support for augmented reality and other things. Geolocation and background app activity are some of the things that are a little more clumsy at the moment and could be improved."
"Ionic's UI component doesn't always look like the native mobile app."
"It would be better if it had a speed niche system."
"It would be good if the mobile version uses something other than JavaScript and HTML."
"It would be good if the mobile version uses something other than JavaScript and HTML."
"There is a lack of a community environment, and the solution lacks developer opinions."
"In a future release, we would like to have a little more support for the desktop environment. Currently it is still focused on mobile devices."
"There's no direct tech support."
"For small companies the pricing can be a bit steep."
"Mendix could improve in customization and UI, UX flexibility, native mobile development, and agile tooling for developers."
"The area of this product that needs improving is the templates in which the user uses to create documents."
"The cost model could be better. It is expensive."
"The platform still has many areas for improvement."
"We need better reporting and visualisation as this is a critical part of each app and currently the reporting side has to rely on external BI tools."
"Integration with external databases can be slow, and it burdens queries when trying to pull large datasets, thus slowing down page execution."
"Currently, in mobile applications, we don't have push notifications."
"The PDD framework can't be used for the behavioral-driven development way of working."
"Since we first started using OutSystems, they switched their language support from Java and .NET to .NET only, which was a bit of a surprise. Their language support could be better in this sense, although on our resource side it is now a bit more flexible."
"The documentation needs to be more robust."
"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."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"It needs improvement in the AI capability."
"The initial setup is a little difficult."
 

Pricing and Cost Advice

"Ionic is an open source solution, and there are no hidden fees."
"I think most of the plugins for Ionic are open source, and you can do a lot with many of the basic features. However, if you need to use a premium plugin for something like extra scroll list functionality, Ionic will ask for a certain sum of money."
"The solution's open source option is free with no licensing fees."
"Ionic is an open-source solution, it is free."
"You can use the free version, but if you still want to buy it, the price starts from $499/month."
"We pay 50,000 dinars per month."
"The starting cost for the enterprise option is around one hundred dollars per month."
"You don't have to pay anything except for certain projects. For example, Appflow has some costs related to it but you don't have to use it. You can also pay for extra support."
"Initially, we started with a year for approximately $25,000, and if we need to expand the number of seats then we will increase it."
"I would not recommend the solution to small and medium-sized businesses because it’s expensive. It’s great for big organizations. I rate the pricing as a three out of ten."
"The solution is a bit expensive compared to others"
"Licensing costs are similar to those for all other IT technology, but they vary by region."
"Mendix is not open source, but its license cost is cheap, particularly when compared to the Appian license. The license model would depend on how many users you have and how many applications you are creating. If you are creating a single app, you just need to have a single app license, so it's free. If you want a multiple app license to cover two thousand or three thousand users, for example, internal users or external users, then you need to pay for the license. There's also a license model for above three thousand or four thousand, or five thousand internal and external users."
"Mendix seems a bit expensive. But in terms of wanting to have less developers and higher velocity, the total cost of ownership is fine. It's not cheap, though."
"From a commercial point of view, we would like them to change that they currently sell it as a platform, but as a customer you have to decide upfront the usage of the platform. We would like to have Mendix sell it as a pay as you go model: You pay for what you use, and you don't pay for what you don't use."
"Pricing used to be complex, but Mendix has improved that quite a bit."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"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."
"For a single application, it's too expensive."
"It's not cheap. It's pretty expensive."
"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."
"There are no additional costs with the standard license."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
