I'm also aware of UiPath and Blue Prism. 

I previously used Pega Robotics and will always recommend that as my preference. 

When we were working on the client’s project, we suggested to the client that we would pay for the solution and do the procurement. So to make it cost-effective, we went with INTELLIBOT. As compared to other RPA licenses, INTELLIBOT is quite cheap.

We have used UiPath and compared to it, INTELLIBOT is easier to use and deploy.

One of our clients that were using UiPath encountered processes that they were unable to automate. They switched to INTELLIBOT to get it working.
