Both UiPath and OpenBots are robust enterprise grade platforms for automating business processes. They both provide tools that enable development of automation code and execution and management of this automation code executed by digital workforce (Robots). In addition to the core build, run and manage features, both also offer sophisticated components for human in the loop execution, Forms/Apps for data capture during execution, and cognitive execution for document classification and data extraction. There are also additional tools that help you measure your automation program metrics by building dashboards that provide process execution insights to operations and business teams.
The main difference between the two platforms is the cost. With its Zero Bot licensing model, OpenBots enables scalability of automation programs. Whereas, with UiPath your automation pipeline tends to be much smaller as the number of ROI positive automations is much lower. This is due to the expensive licensing cost which increases with every Robot you put in production resulting in significantly lower benefits from the program.
Both UiPath and OpenBots are very mature products that provides capabilities around all aspects of automation analysis, design, development, and delivery of automation projects. For most part they are at feature parity. There are some areas where UiPath offers additional capabilities for process discovery. They have add-on components for process mining and task mining which OpenBots currently offers as partnerships with other providers. On the other hand, OpenBots strength is their orchestration capabilities. With OpenBots you are not only able to orchestrate automations that are built using proprietary low code OBScript but also automations which are scripted using popular languages like C# and python. Additionally, the auto provisioning capabilities help dynamically increase the number of robots for higher concurrency to cater to higher transaction volumes. Other OpenBots differentiating features include a development SDK to build custom commands (Activities), business events, email gateway, rules engine (In development) etc.
UiPath has the largest market share and adoption rate today. They have the largest development network. OpenBots is built on similar technology stack and makes it very easy to learn for developers that are already familiar with UiPath. OpenBots also provides various enablement and training programs and has a mature product academy and certification program for self paced enablement.
