Hey @Vlcky, the community version is an always free version with limited features, useful for Developers, and small team beginning their automation journey. Whereas Enterprise version is a full-fledged UiPath Studio-cum-Robots-cum On-premise Orchestrator version. The decision to choose on-premise or on cloud should be taken keeping in mind your automation needs depending on the use case you are working.

Hope this helps!
