With low-code, we don't need a lot of coding, and then from the plumbing perspective, there is a complete CI/CD pipeline that exists within Appian that can be leveraged for open deployment.

It has good integrations. We were looking for out-of-the-box integration with both on-prem and publicly accessible data sources. We needed integration with the cloud, OData, our REST API feed, and then on-prem passthrough to go to a SQL database or on-prem APIs through Azure local deployment, etc.

The most valuable features of Appian are the VPN engine, it is fast, lightweight, and easy to set up business rules. Business teams can do it by themselves. That is a very good feature.

Appian is a great tool for internal use cases where the users are company employees, but it has room to improve for use cases where the users are public facing, where anonymous users could come to a site and run a business workflow or interact with some data.

I think Appian could improve by adding its own native GenAI and agentic capabilities.

If there is a very complex process that includes a lot of data transitioning and memory-centric processes, it consumes a lot of memory.

There are some restrictions with respect to using external components within Appian. So, for example, if we do not have a particular feature available, there's a long cycle of getting approvals and all of that. That does not offer flexibility, which definitely can be improved on.

The tool itself is pretty good, but the main area that we struggled with was the backend. The frontend development is really good, but the backend modeling can be streamlined a little bit. There are good integrations, but tying them through the data layer and then up into the frontend could be improved a little bit. It does read/write on the data source, and you can configure it to just write or just read, but there is a little bit of work involved.

Occasionally, certain pre-made modules may not be necessary and customers may desire greater customization options. Instead of being limited to pre-designed features, they may prefer a more flexible version that allows for greater customization.
