Appian
Chose Appian
Appian is a much more well rounded tool that is easy to learn and provides a much cleaner user interface.
Chose Appian
The main advantage of Appian is the ease to design, develop and implement processes and forms in a relatively short time. By using WebServices as the primary integration mechanism, it integrates seamlessly with other systems.

Mendix
Chose Mendix
Mendix is more flexible and custom making oriented than Appian. OutSystems is almost the same as Mendix but more directed to the traditional developer, whereas Mendix is trying to make it possible for everyone to be able to model.
Chose Mendix
they are good but Mendix is more of enterprise grade. Mendix has many modules available and ready plug ins
Chose Mendix
Most flexible and scalable platform
Chose Mendix
I prefer Mendix because of its open structure the others mostly have vendor lock-in.

Appian
Appian works great for automating manual processes and integrating multiple systems through its toolset. It gives great flexibility for establishing rules for approvals, routings, escalations, and the like. Because of the low code toolset, it's very easy to deploy and make changes as needed as processes evolve and as the organization learns to utilize the system better. Minimal maintenance is required to support the applications build on the platform. Some of the automated testing integration with tools like Jenkins is limited so that may be an issue for some.

This is a superb tool if your project involves a lot of backend development, especially in Java/Spring Boot and Kotlin. The support for the front end is great as well, but some developers may prefer to use the GitHub copilot add-on. I especially love using the GitHub copilot add-on. It may be less appropriate if your project requires heavy use of HotSwaps for backend debugging, as sometimes the support for that can be limited.

Mendix excels in scenarios involving Business Process Automation, making it a strong choice for applications requiring workflow automation, including processes like request approvals, document management, and other business workflows.Conversely, Mendix may be less suitable for projects that demand highly customized solutions with extensive custom coding. Its primary focus on low-code development may not align well with the requirements of projects that heavily rely on intricate and specialized coding.

Pros
Appian
  • Allows at a glance workflow documentation which assists in the need we have for information readiation.
  • Drag and drop interface for workflow development greatly speeds our apps time to market.
  • Using the advanced features of Appian, we are able to create working sites in a fraction of the time it would take to do so using "traditional" development.

  • Unit testing: Fully integrated into IntelliJ IDEA. Your unit tests will run smoothly and efficiently, with excellent debugging tools for when things get tricky.
  • Spring integration: Our Spring project using Maven works flawlessly in IntelliJ IDEA. I know firsthand that Apache is also easily and readily supported too. The integration is seamless and very easy to set up using IntelliJ IDEA's set up wizard when importing new projects.
  • Customization: IntelliJ IDEA comes out of the box with a bunch of handy shortcuts, as well as text prediction, syntax error detection, and other tools to help keep your code clean. But even better is that it allows for total customization of shortcuts you can easily create to suit your needs.

  • We're able to really easily develop different views that are very specific to a customer's needs or customer's different types of user needs. So for example, the production managers can have a certain view that's relevant to them and then certain line managers can have views that are specific to them that allow them to run different scenarios which they define. So it allows us to easily build customized apps for each different type of user.

Cons
Appian
  • Search issues when type ahead and database search are used in the same field.
  • Buttons implementation where user is require[d] to click on the button description - if clicks on the button outside that text - button will not work.
  • Problems with using certain off-the-shelf performance tools like WebLoad or Neoload. That is because of different dynamic variables being used internally in Appian - which these tools are unable to correlate. We are still investigating using other tools like Jmeter to overcome dynamic correlation problem for performance testing.

  • Finding if a feature exists or not in IntelliJ IDEA can be challenging.
  • For example, if we know how to format a particular file, the command is Ctrl+Alt+Shift+L, but if we don't, then finding it is difficult.
  • Setting up a project interpreter and directory structure might not be intuitive at first.
  • Git integration can be improved. For example, it isn't easy to rebase using UI in IntelliJ IDEA.

  • Earlier versions lacked in UI/Ux. This is still improving.
  • Since everyone and anyone can create custom add ons (widgets), Mendix could improve their quality checks (but not as rigid as eg Apple).
  • Upgradeability used to be somewhat of an issue. Version 7 looks to be handling this better than previous versions.

We recently renewed our license with Appian. We are convinced that its flexibility, relative ease of use, the support they provide, there mobile advancements and their general willingness and desire to see us succeed all contributed to our reason to renew our agreement with Appian

VS Code is maturing and has a Scala plugin now. The overall experience with VS Code - for web development at least - is very snappy/fast. IntelliJ feels a bit sluggish in comparison. If that Scala plugin for VS Code is deemed mature enough - we may not bother renewing and resort to the Community Edition if we need it.

Usability
Appian
Appian is a low code environment, because of this, a very good visual interface is required. Appian is providing a feature-rich dashboard [that] we can use for building the dashboards and other interfaces. Appian also provides patches and releases to enhance these features. A developer can start off development just by going through a basic course from the Appian learning community.

There is always room for improvement, but I haven't met any IDE that I liked more so far. Even if it did not fit a use case right out of the box, there is always a way to configure how it works to do just that.

A 10 would say I have nothing to wish for. A 9 means I haven't seen anything better.This tool really helps you in the whole creation and maintenace cycle, so from requirements to building/modeling to testing to deploying to capturing feedback.

Appian
Appian is one of the leading low code business automation platforms that support RPA, decision rules, case management, workflow automation, and machine learning all in a single bundle. But it is also harder to implement and replace the traditional business process.

Customer support is really good in the case of IntelliJ. If you are paying for this product then, the company makes sure that you will get all the services adequately. Regular update patches are provided to improve the IDE. An online bug report makes it easier for the developers to find the solution as fast as possible. The large online community also helps to find the various solutions to the issues.

This installs just like any other application - its pretty straight forward. Perhaps licensing could be more challenging - but if you use the cloud licensing they offer its as simple as having engineers login to the application and it just works.

Eclipse is just so old, like a dinosaur, compared to IntelliJ. There are still formats that Eclipse supports better, especially old and/or propriety ones. Still, most of the modern software development needs can be done on IntelliJ, & in a much better way, some of them are not even supported on Eclipse.

Mendix would be my preferred system all the way. The system is designed for these kinds of works. I've worked with WP and DNN but they should be used just for websites. To create an app for a business value, I would suggest Mendix. Also, the offline capabilities of Mendix have greatly improved since the deployment of Mendix 7.13.

Return on Investment
Appian
  • I believe it has negatively impacted our release dates. There may have been a misunderstanding as to the learning curve, even though it is "low code."
  • The look and feel of the applications created using Appian have uniformity and it's easier to have "reuse" between applications.
  • There is less developer control when it comes to features. I think this mainly has to do with the amount of plugins available. I would think there should be many more available plugins. But again, our use case is probably different than most others.

  • Easier to find bugs and debugs, thus reducing man hours and generating immediate dollar impact.
  • Coding time is lessened, which in turn again reduces man hours and generates immediate dollar impact.
  • Refactoring code is more innovative and easy here, resulting in more maintainable code.

  • It helps to speed up application development because of its low code by the fact that it's low code. It allows professional developers to focus more on specialized application development rather than the more routine application development that business IT and super users can do for themselves with some coaching from the IT department. So it's just allowing the more specialist professional developers.net, for example, Java in our organization to focus on more complex engineering application developments.
