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

"The automation part is extremely helpful in streamlining our processes."
"We do not need to pay for the solution. It’s free."
"It is an indispensable tool for mobile automation helps much in converting manual test cases to automated scripts."
"The latest versions of the solution are stable."
"The most valuable feature of Appium is it supports iOS and AOS and is open-source."
"Appium's wide support of programming languages is valuable."
"Obviously because of automation, it reduces manual testing efforts."
"Our clients have realized benefits by reducing their testing cycle from three days to three hours through Appium."
"Let's assume a project in .NET, native .NET, or Java takes around 12 months. In OutSystems, we can build that application in four to five months."
"The most valuable feature of OutSystems with discipline and the development processes. Instead of each developer doing tasks on their own with their own approach, et cetera, the solution would help bring some organization to the development process."
"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."
"Once built, web/mobile components can be reused in all new developments. In addition, the OutSystems Forge is very useful. We can exchange components and even already-built applications, reducing costs to build specific solutions."
"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."
"We used almost all of the features, themes, styling guide, and approach components. They are useful in our applications."
"It provides for faster development and better software releases."
"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."
 

Cons

"The tool needs to add a dependency manager."
"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."
"Support-wise, it could be better."
"Configuring the project to be used in Appium is a little bit tedious."
"We previously worked with native applications, and there weren't any good mobile app testing tools. We started working with React Native, which works well with Appium, but it would be good to see better integration; the way elements are displayed can be messy. React Native is very popular nowadays, so it's essential to have that compatibility."
"The initial setup is straightforward if you have previous experience with the solution, but it can be complicated for a novice user."
"The installation part of Appium is somewhat clumsy, requiring numerous dependencies and configurations."
"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."
"The latest version of the app generation tools could be more user-friendly."
"We have performance issues while fetching bulk data."
"The product could be improved if there was a shortcut, or predefined, predictable templates provided."
"The documentation needs to be more robust."
"The customer service and support are maintaining a two-day SLA for everything. 48 hours is very high."
"Since we first started using OutSystems, they switched their language support from Java and .NET to .NET only, which was a bit of a surprise. Their language support could be better in this sense, although on our resource side it is now a bit more flexible."
"Mobile apps should have been fully native."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
 

Pricing and Cost Advice

"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."
"Appian is open-source, which is not licensed."
"The solution is open-source."
"As far as I know, Appium is a free solution. It's not for commercial use."
"Appium is open source; we can use it for free."
"Appium is free and open-source."
"The solution is open source."
"The pricing of Appium is fine."
"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."
"It's not cheap. It's pretty expensive."
"The price is okay. OutSystems isn't expensive. It's a mid-range solution."
"It is too expensive for small companies."
"I believe they are very strict with their pricing platforms, or the pricing policies, and it changes."
"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"The solution is expensive."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
