Featured Reviews

Julius Jagdon - PeerSpot reviewer
The tool is intuitive to use and, through automation, has been a real time-saver
When there are multiple steps or if there's a disconnect when creating the ticket, it could be a problem for the user. For example, our RSN needs to approve the ticket first before it's moved to the next person rather than having them all grouped. It would be better if we could see all the tickets grouped at the same time.
Sukrut Joshi - PeerSpot reviewer
Enables users to develop applications quickly and has a responsive and helpful technical support team
The time to market is quite good. We can quickly develop an application using the tool. OutSystems is developed using .NET and Java. We can easily find technical resources who have worked on .NET and Java and leverage their previous knowledge to develop OutSystems applications. It can also be used for application development. If an end-user does not want to use the solution after two to three years, OutSystems sends the source code and the applications to the end-user. There is no dependency. It’s one of the major factors I found quite good in OutSystems.
