I think it's well suited if you have data available and you want to create customized solutions for different types of users. Mendix is very good at doing that. It allows you to do it very easily. So those are good use cases.
PowerApps is well suited for "quick-wins" and fast prototypes of business solutions. It also is beneficial for situations where business partners and developers work together - it allows the business folks to provide a "quick-and-dirty" prototype which is then fleshed-out by developers that are trained experts on the platform. The interactive and easy to understand representation of the solution allows business partners to "see" the solution and add, remove, or correct aspects of it themselves. It provides a common view and understanding of the actual solution across business units and tech teams. PowerApps, being a low-code\no-code platform is not well suited for business processes that require many complex computations or large amounts of custom code - such as solutions that are better architected as Web Site or "full-blown" desktop solutions. There are solutions that are just not easy or quick to accomplish in a low-code\no-code platform. Enterprise Architects should know the difference, however business partners often try to create a solution and only when stuck because it becomes too complex do they engage a tech team for assistance - at which point there are sunk-costs involved and hinderences to re-platforming the solution
Power Apps has formats that are pre-built that don't require any coding which makes it easier to achieve your vision. This does become a challenge if your App needs don't fit into that format.
We deal with a ton of data so the fact that you can connect to any data source in addition to their pre-stablished data connections makes the process a breeze.
The online learning resources and tutorials are helpful as well for those who are tech savvy.
PowerApps has a great coding option, but there are some pieces of the tool that the requirement to understand code is a barrier to fun if the user doesn't code.
MUCH time can be spent looking for solutions on this young platform and the body of forum/help/lessons learned is not as robust as it will be in a few years.
Like many early-stage Microsoft products, PowerApps is a relatively blank slate that will be improved by the feedback of their users and ongoing feature development. Right now it seems that the product lacks a critical mass of use-case driven templates (there are some, but I haven't yet found one that didn't require more work to customize it to my need that it would take to build my own tool).
Drawing from my hands-on experience with Mendix, I can confidently state that the platform aptly fulfills our needs for web application development. Mendix stands out by providing a marketplace replete with pre-built templates and widgets. This feature empowers users to leverage readily available components, hastening the development process and contributing to an enhanced overall usability of the platform.
PowerApps is a great solution and I have spent the last year familiarizing myself with the platform and building custom applications to complete a whole range of tasks such as asset management, custom invoice generation, and item restriction tracking. We as a company have barely begun to scratch the surface of what can be achieved with PowerApps.
I think their support system is really professional. They answer question quickly and accurately. They have a ticket system that allows to track the current status of a request. The only point for imporvement is a way for me to postpone an answer. Tickets get closed automatically after some time. I feel that the user should have the option to change to an on hold status, allowing for more time to respond to a ticket.
The community forums are extremely responsive to questions asked, there is a good body of online documentation and many community posts to draw from. Although the platform has changed, which means some of the posts are out of date and the solutions provided aren't relevant. Of relevance, I read over 400 articles plus documentation to get this first app built in SharePoint, move it to SQL and make it work exactly the way it should.
Because most of our apps work closely with our main system (ERP) and other tools, we went with Mendix. It's good at easily connecting with lots of different systems, which is exactly what we need. Another thing we like about it is that it can handle growth well, and its pricing is straightforward and easy to understand.
1. PowerApps functionality comes with E1 over E3 License without adding extra costs 2. For Nintex you pay (at the beginning) for each workflow, so my intention would be, to do no workflows to prevent additional costs, but I want a platform with a fair price that allows me to create workflows without thinking about the price for each workflow and we use only some workflow and relative easy workflows and forms as a medium-sized company. 3. PowerApps provides a lot of functionality without needing to invest in premium features directly.
Without Mendix we could not have been where we are now. A development platform as Mendix can make the difference in a constantly changing environment.
Upgrading to newer versions of Mendix is a breeze when you stay within a main version (e.g. M6.x to Mx6.x+1) and even between versions (Mx5 to Mx6) most of the time it is no problem at all and there are only minor changes needed to upgrade.
Learning Mendix is simple. Just start playing with it and see for yourself how easy it is and feel the joy of developing applications.
