Independent consultant, at OpenText
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.

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

"For the particular use case we used Appium for, we felt that it served our purpose completely, and we haven't had any issues with the Python Client for Appium."
"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 way Appium server interacts with mobile apps is fantastic. It provides all the information about the elements inside the app, Android as well as iOS. I can interact with the element quickly, just type some text or get some text values from the element - whether it's a drop-down, or web text, or a native element."
"It has great documentation and excellent community support."
"This solution has improved our organization in terms of efficiency."
"The best feature of Appium is that it allows you to inspect the element. With the Appium Inspector, you don't have to install another application to do the inspection. I also like that Appium has Android device connectivity. Currently, most people use Appium as automation software, and I haven't found any other tool that's more powerful than Appium."
"It can be used with different programming languages."
"The library is extensive so the driver interacts with most functions or actions on mobile devices."
"Before OutSystems we used to take six to seven months to build applications, now, using OutSystems, it just takes two to three months, max, and the best part is that one or two developers can create a full application."
"Setup is easy, the solution is also easy to learn and there is a lot of community support on forums to help."
"We have no complaints surrounding both the scalability and stability of this solution."
"One thing I like about OutSystems is that there's no lock-in. You can keep running your applications because it's on .NET and hosted centrally. That's one of the advantages I see there in terms of not having an IT strategy that has a dependency on a particular platform."
"OutSystems' best feature is that you can build tests with the flow, so even the tests are made in the PDD framework in a low-code way."
"Our previous solution had other overheads such as release management, version management, code management, monitoring, etc., all of which are built-in with OutSystems."
"The most valuable features of OutSystems are the user-friendly platform. The drag-and-drop feature is great. I have used other rapid application development tools before, but they were not as advanced as OutSystems. With the previous tools, I had to manually build certain features, but OutSystems does it automatically."
"Integrations with external systems with SOAP and REST are easy to implement off-the-shelf, but a developer can always implement specific libraries for other integrations."
 

Cons

"If it had more facility for configuration it would be a spectacular solution."
"The deployment process and configuration are quite complex and require improvement."
"One thing which can be really helpful is that there is some kind of a recorder made available rather than scripting everything."
"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."
"There is always a concern about the amount of code that is required to enhance the automation process. The idea of having less code or no code is what we would like to see in future updates."
"The product was a bit difficult to install. It wasn’t easy. We had issues."
"It breaks down."
"They can improve test reporting, and more importantly on test scripts, by providing less constructs to automate more complex testing scenarios."
"The tutorials for the solution should be updated."
"Mobile apps need improvement."
"The small-scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost."
"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 is a little difficult."
"We'd like OutSystems to add stronger workflow-based automation similar to what Appian offers. It needs more workflow modeling and RPA features."
"I have difficulty in using several new features. Some of the product's features are tricky to use as well."
"Writing custom code still needs to be done via Integration Studio. This might have been added to the IDE."
 

Pricing and Cost Advice

"The price is good for people to be able to make a favorable decision for the value."
"Appium is free and open-source."
"As far as I know, Appium is a free solution. It's not for commercial use."
"It's completely 100% free, and there are no hidden fees."
"The solution is open source."
"I'm unsure if there's any cost associated with Appium. I got the free package which includes the server GUI application and the inspector application, and it was free to download, and that's all I need to get my work done. I'm not aware of any additional costs associated with the tool."
"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."
"The solution is open source so it is free."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"For a single application, it's too expensive."
"For one developer to use, the cost is around $5,000."
"OutSystems is a good solution, but it's not cheap."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"There are no additional costs with the standard license."
"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."
"I would rate it five to six out of ten."
