Featured Reviews

Sameer Verma - PeerSpot reviewer
Low-code, helpful support, and great native mobile capability
There is always a layer of custom code required. There is a misconception of low-code, or Mendix, or the industry in general. They are perceived as more of a dashboarding tool, and as a visualization platform only, rather than building a complete enterprise solution. That's more of an awareness marketing challenge they have, or the industry has. In general, AI needs to be better. The team and the company is running ahead with this a bit more. AI area is something which companies have started to pick up on, low-code wise, and they should invest in it more. I would like to see their data hub module become a little bit more mature. They need to expand their base as the concept is amazing. We just need to see more use cases and learn more capabilities there, and then definitely they need to fill in the AI piece of it.
Bireswar Das - PeerSpot reviewer
A low-code platform for the development of mobile and web enterprise applications
To illustrate a case, the customer initially had a private cloud, essentially a data center hosted within it. They needed a disaster recovery solution, which would involve using a public cloud. This situation led to some deployment challenges due to the hybrid nature of their setup. However, once we implemented the solution for them, they were extremely satisfied. The process was not only effective but also quite speedy. To be more precise, we completed it in around 100 days, even though they initially requested it to be done in four months. They were very pleased with the efficiency of the implementation.
Zain Omer - PeerSpot reviewer
Though a secure tool for building applications, there is a need to improve its stability
There is a lot of room for improvement in Temenos Quantum. Temenos Quantum is not quite stable yet. Improvements can be made to make Temenos Quantum stable. Improvements are needed in the solution, considering how my company needs to raise a lot of tickets with the technical support team of Temenos for some basic issues every time. There are some features in Temenos Quantum that I want to be stabilized by Temenos, just like in Android Studio and Xcode. Building an application using Temenos Quantum is not difficult, but my company needs to seek some support for the solution all the time.
