Featured Reviews

Srimanta Pandit - PeerSpot reviewer
Flexible, improves operational efficiency, and reduces the time taken to complete processes
The solution’s turnaround time for development is better compared to other tools. The solution enables fast development. The traceability of the processor is good. There is much more governance and regulations on the processers. The tool reduces the time of the processes by 30% to 40%. The solution’s low-code aspect has greatly impacted the development and deployment speed. One of the major reasons we are using the product is that we can reuse the modules. The developers can reuse all the modules. It enables us to make subsequent developments in less time. The prebuilt modules can be deployed within two to three weeks. The tool is very flexible. Compared to other platforms, the Appian product team was agile in quickly customizing things for us.
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.
