Comparisons
Compare every event diagramming tool
In 2025, Cvent — which already owned Social Tables — acquired Prismm (formerly AllSeated) and began consolidating both into Cvent Event Diagramming. Every comparison in this space is now really one story: the two main tools merged into one enterprise product with annual contracts. These pages lay out the details honestly, including where Cvent wins.
