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.

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

"I like the app inspector; it's quite a good and useful tool for us, we can use it almost out of the box, it works well on Android, the solution is stable and very scalable, and it is free to use."
"I like that Appium is an opensource tool, I also like its cross-platform flexibility, and Appium provides a record-and-play option with commands that are the same as those that Selenium uses so a person who has some exposure to Selenium will be able to write a piece of code in Appium."
"The latest versions of the solution are stable."
"The most valuable feature of Appium is it supports iOS and AOS and is open-source."
"The most valuable feature is that it's easy to launch applications. Appium has everything that Selenium has. So many good tools support Appium. We can take some Excel sheets and use them to fill out the text box that's in there. We can also take screenshots of failures."
"Within a single command, we can easily connect to the device."
"It can be used with different programming languages."
"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."
"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 architecture of OutSystems is quite simple, and the features are similar to Mendix's. OutSystems has connectors for different enterprise apps and solid reporting capabilities. You can also integrate with any content management platform like SharePoint or Adobe Enterprise Manager, or something like that. You can also create and integrate workflows."
"We can do the validation before calling the API."
"Their drag-and-drop functionality is amazing."
"OutSystems' low-cost approach has positively impacted our productivity, because we were able to develop faster with OutSystems, enabling us to implement many changes during our sprint."
"Setting up OutSystems is easy. It take one or two hours."
"We have no complaints surrounding both the scalability and stability of this solution."
"I think OutSystems provides one of the best trainings out of all similar platforms."
 

Cons

"Appium has problems with automated validations following iOS updates, causing us to have to validate manually. Its execution speed is also very slow."
"Sometimes, the Appium server won't connect with the mobile application because of some socket issues, so network connectivity between applications and the Appium server could be improved."
"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."
"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."
"If it had more facility for configuration it would be a spectacular solution."
"Installation of this particular tool is tedious, and it gives you a good number of challenges at times."
"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."
"Image recognition could be improved. We have some images in our mobile applications. It should be able to run from the cloud, so we can automate the catcher."
"It needs improvement in the AI capability."
"The prices should be lower. It is a little bit too high for a small market."
"I like the OutSystems platform. I am working on integrating it with another platform using APIs, however, it has proven to be difficult. The main issue I am facing is obtaining authorization tokens as well as access and refresh tokens. It may be due to my lack of knowledge of APIs as it is new to me."
"The resource availability needs to be increased."
"I've read that where you have large deployments, OutSystems starts to crumble a bit."
"The solution is costly."
"One of the things that they could do a little better is the performance speed of the UI refresh; it sometimes seems a little choppy, and I would have to reload the same page a couple of times to get the reflection of the right information."
"The tool needs to improve the efficiency of its widgets."
 

Pricing and Cost Advice

"It's completely 100% free, and there are no hidden fees."
"The solution is open source so it is free."
"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."
"As far as I know, Appium is a free solution. It's not for commercial use."
"The solution is open source."
"Appium is free and open-source."
"Appium is open source; we can use it for free."
"As for licensing costs, I'm not directly involved in that aspect."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"There are no additional costs with the standard license."
"It is too expensive for small companies."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"I believe they have two pricing options. One is approximately $4000 USD a year and the other is approximately $10,000 USD a year."
"The subscription is billed on a yearly basis."
