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.

Senior Technical Lead at a manufacturing company with 5,001-10,000 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

"Overall, Appium is the best; it has the flexibility, simplicity, and it is elegant, technically more advanced, and even a beginner can start using Appium very quickly and master it in less time."

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

"The most valuable features of Appium are the in-built functionality, which we can use in our code. For example, move back, move front, navigate one page before, and navigate one page ahead. You can do this by using the in-built functions from Appium."

"It has great documentation and excellent community support."

"It runs completely flawlessly and seamlessly every day."

"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."

"Currently, most people use Appium as automation software, and I haven't found any other tool that's more powerful than Appium."

"It's one of the most stable solutions for mobile automation."

More Appium pros

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

"The solution is stable and doesn't require many server resources, so I don't think there are stability issues."

"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."

"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."

"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."

"The product is mostly stable."

"Setting up OutSystems is easy. It take one or two hours."

"Some systems have over 1,000 end users; it's very stable for heavy duty operation."

More OutSystems pros

Cons

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

"The challenging part with Appium is that installation can be a bit tricky. It can be challenging to set up in Android versus iOS environments."

"Installation of this particular tool is tedious, and it gives you a good number of challenges at times."

"The deployment process and configuration are quite complex and require improvement."

"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."

"Appium can improve when the case fails, there should be a feature where you can generate the report from Appium."

"What needs improvement in Appium is its documentation. It needs to give more context on the libraries that Appium is using under the hood. For example, my team is using Appium for Android automation, and a lot of times, I feel that there's functionality that's available through the Appium interface, that exists within the UIAutomator, but there aren't a lot of useful or helpful resources on the internet to find that information, so it would be good to have some linkage with the underlying platform itself. Another room for improvement in Appium is that it's buggy sometimes. For example, at times, there's a bug in the inspector application that doesn't allow me to save my desired capability set, so it would be nice to get that bug fixed, but overall, Appium is a good tool. The Touch Actions functionality in Appium also needs improvement. For example, if I want to initiate a scroll on the device that I'm running Appium on, sometimes Swipe works, but in other situations, I have to explicitly use action chains, so I'm not too sure what's the better approach. What I'd like to see in the next version of Appium is a more intelligent and more intuitive AppiumLibrary, in terms of identifying menus and scroll bars, etc., because right now, I'm unsure if I have to do a lot of export reversals to get to the elements I'm looking for. It would be nice to have some functionality built in, which would allow me to easily get those exports."

"Support-wise, it could be better. Whenever we get some issues, it may take some time."

More Appium cons

"The tutorials for the solution should be updated."

"The product's high price is an area of concern, where improvements are required."

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

"When shared extensions are updated, all the applications are redeployed."

"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."

"I've read that where you have large deployments, OutSystems starts to crumble a bit."

"It needs improvement in the AI capability."

"The initial setup is a little difficult."

Pricing and Cost Advice

"Appium is open source; we can use it for free."

"There is no license for this solution because it is open-source."

"The price is good for people to be able to make a favorable decision for the value."

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

"Appium is free and open-source."

"It's open source, so it's completely free."

"The pricing of Appium is fine."

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

More Appium pricing and cost advice

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

"The tool’s licensing is based on the user’s usage."

"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."

"The solution is 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 is a free trial to use this solution and other options available, such as enterprise. There are different subscription plans."

"For a single application, it's too expensive."

"For one developer to use, the cost is around $5,000."
