Executive SummaryUpdated on Mar 4, 2025

OutSystems and Appium operate in different sectors of the tech industry, focusing on application development and mobile app testing, respectively. In terms of development, OutSystems holds an advantage due to its rapid low-code features, whereas Appium stands out in mobile testing with its cross-platform flexibility and language support.

Features: OutSystems facilitates development with one-click publishing, robust SOAP and REST API integrations, and the ability to reuse components across projects. It also supports agile development with visual modeling and drag-and-drop functionalities. Appium, leveraging Selenium, enables scripting in Java, Python, and other languages and supports multiple platforms like Android and iOS, aiding efficient mobile testing.

Room for Improvement: OutSystems could enhance the speed of Service Studio and develop more robust mobile app features. It also needs improvements in UI component customization and complex logic implementations. Appium would benefit from improved documentation, better stability, and advanced platform support, such as AI self-healing script features.

Ease of Deployment and Customer Service: OutSystems offers flexible deployment options, including cloud and on-premises solutions, and proactive yet sometimes slow customer support. Appium, being open-source, heavily relies on community support and offers a straightforward deployment, mainly on-premises.

Pricing and ROI: OutSystems comes with high costs, approximately $4,000 monthly, which may challenge small businesses, but delivers substantial ROI due to development speed and efficiency. In contrast, Appium is free, making it appealing for those on a tight budget, despite lacking direct official support, providing significant savings in licensing costs.

Efficient mobile testing with intuitive emulation capabilities and a user-friendly interface

Initial setup for Appium (especially for iOS) is not beginner-friendly.Consumes too much of your host machine's resources, potentially slowing down the machine.Appium Inspector often lacks deep insight or crashes with certain app builds. Improve test flakiness by intelligently selecting robust self-healing locators,simplified installers, better documentation, GUI-based config management,smart wait mechanisms and better failure logs.

OutSystems facilitates rapid application development and effective project management

What I find valuable about OutSystems is that it has a very good learning curve for developers. Within two weeks, we can gain knowledge in OutSystems, and it is very easy to learn. With my background being .NET, OutSystems is straightforward to learn, which is beneficial. Developing applications in OutSystems is good, and the flexibility allowed by OutSystems for application development is excellent compared to my experiences with other low-code technologies, where I've faced some challenges. The clean separation of concerns in the architecture provided by OutSystems is a key benefit compared to other platforms. OutSystems integrates with our existing tech infrastructure and provides flexible integration. If we want to integrate with third-party services, OutSystems has SOAP and RESTful services that allow us to consume external services, integrate with external databases such as SQL or Oracle, and includes integration studio for writing custom .NET code. After developing a .NET component, we can reference it in service studio, creating a reference file that makes integration easy. OutSystems officially supports various integrations and also includes an API discovery tool for consuming and exposing services, providing a lot of information about incoming URLs, similar to how we use Postman.

Quotes from Members

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

Pros

"We do not need to pay for the solution. It’s free."

"It runs completely flawlessly and seamlessly every day."

"Appium's best feature is that it supports multiple frameworks."

"We get a list that shows all devices that are connected to the system."

"I haven't explored other solutions in this particular area, but what I like best about Appium is the fact that it shares functions with Selenium. The extension of Selenium functions allows me to use all of the methods that exist in that domain, and it just makes it simpler for me. I've been using Selenium for some time as well, so using Appium just seems like a natural fit for me."

"We develop apps using the React Native framework, and Appium integrates well for testing those apps. The Appium automation framework also has good integration with GitHub Actions and plenty of other tools and frameworks, including BrowserStack."

"The automation part is extremely helpful in streamlining our processes."

"Appium helps me to do as much as much as I want to."

More Appium pros

"I like the mobile features the most, and there are also various features around the portal we created that I enjoy."

"OutSystems has no issues so far, the drag and drop environment is quite dynamic, and we can create our own UI on top of it."

"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."

"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."

"We can quickly develop an application using the tool."

"It is easy to use."

"It is a scalable solution...The initial setup of OutSystems is easy."

"The most valuable feature of OutSystems is the drag and drop and toolchains in the small AI developing environment. Additionally, the documentation is helpful."

More OutSystems pros

Cons

"Support-wise, it could be better."

"We haven't been able to fully leverage Appium for multiple reasons. I think number one is just that the tests take a long time to run. We have had some issues around just the results themselves and how predictable they are, but those are not issues with Appium directly."

"They should add an in-built framework."

"One area where I think Appium could improve is in addressing security concerns for our data. Currently, we're unable to use cloud solutions like CloudForm due to security restrictions on our servers. We also face challenges in updating packages for the same reason. It would be beneficial if the solution could provide better support for auto-reporting and easier connections to mobile device farms."

"An application developed on the Unity platform, such as a gaming application, objects are moving in that case. Interacting with those elements is still lacking in Appium. Appium doesn't have the internal library to play with the Unity platform. That is a huge lack right now."

"I rarely use Appium nowadays because I'm now at the managerial level, but the last time I used it, whenever I selected and clicked on an element, Appium was very slow. I tried to debug it, but I still couldn't find the problem, so this is an area for improvement in the solution. Another area for improvement lies with the connector and server. For example, the effort to get into the local machine sometimes causes the emulator to become slow, which then leads to failure in testing, and this is the usual issue I've encountered from Appium. An additional feature I'd like added to Appium in its next release is being able to do automation in iOS without using XPath and the name of the element. In Xcode, you can use previous UI tests for detecting elements, but in Appium, you have to use Xpath and the element name instead of being able to directly put the X-UiPath, which is what you can do in Xcode. In iOS as well, sometimes the element doesn't have a name or a path. Sometimes, there's also no element."

"It needs to accommodate applications that use React.js and AngularJS."

"Appium has problems with automated validations following iOS updates, causing us to have to validate manually."

More Appium cons

"The product could benefit from improved connectors to integrate with outside platforms."

"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 initial setup of OutSystems is not easy. It is a very heavy application that requires a lot of hardware and software resources."

"The largest obstacle currently associated with OutSystems is its high cost and limited availability of skilled personnel. Despite being a rapid application development platform, having a highly skilled individual familiar with the platform can be much more beneficial than an inexperienced individual. Because there is a shortage of people with the necessary OutSystems skills, utilizing the platform can become expensive. This makes little sense, considering that a rapid application development platform should be accessible to the average person. However, having a highly skilled individual can greatly increase productivity, making the cost worthwhile."

"Its ability to create and run automated tasks could be better."

"The prices should be lower. It is a little bit too high for a small market."

"I would like to see more integration between the use of artificial intelligence to speed up the process delivery time."

"There are not enough resources on the market."

More OutSystems cons

Pricing and Cost Advice

"The solution is open source."

"The solution is free."

"We found out that we could explore features of the solution for 30 days trial. We can switch to a permanent license later if we want."

"This is an open source solution so it does not cost anything for licensing or otherwise."

"The solution is open source so it is free."

"Appium is free and open-source."

"The solution is open-source."

"It's completely 100% free, and there are no hidden fees."

More Appium pricing and cost advice

"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."

"It is still very expensive, so small companies can’t generally afford it... Still, the time saving on development and delivery is worth the value."

"Pricing could be a concern. You have to pay yearly, even after you have completed your development."

"It is not an expensive product, especially if you have access to more features and deal with more projects."

"I would rate it five to six out of ten."

"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."

"It is very high price."

"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."
