Room For Improvement

Google Firebase users desire better pricing transparency, technical support, usability, integration, mobile testing, and enhanced tools for developers and non-technical users.
OutSystems requires improvements in pricing, support, AI integration, testing, performance, documentation, containerization, and version control to satisfy users.
Since Google Firebase is a NoSQL platform, areas for improvement include enhancing query functionalities to be more equivalent to SQL, like MS SQL.

Automation testing with mobile devices could be improved, especially in regression testing to ensure that new feature launches do not affect other features.

Himash Careem - PeerSpot reviewer
Intermediate Software Engineer at Xelleron Pty
Analytics integration has improved how I manage user identity and understand customer behavior
I face difficulties with the authentication parts in Google Firebase when it goes with iOS applications. With Android applications, that is easier because Google owns it. When it goes to iOS applications, there should be a much more straightforward, smoother way. I mostly faced that with Flutter because with Flutter, there are two sides with Android and iOS. The Android part was pretty much easier for me, but when it goes to the iOS part, there was more work on that.
Aditya Bhatt - PeerSpot reviewer
Sr. Project Delivery Lead | Sr. 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.
