This page provides a side-by-side feature comparison of OpenRocket and RockSim. Both represent the latest version of the software.

While hosted on the OpenRocket wiki site, we have attempted to make this an objective comparison between the functionality of the two software products. If you think something is wrong or omitted, please contact us.

Usage

One attribute of interest when comparing pieces of software is how much each software is used and how much of a community exists around the software. While it's impossible to get an objective measure of the usage and community activity, Google Trends does a rather good job at providing an indication of the relative interest levels over time.

Since around 2014, OpenRocket and RockSim have received approximately the same amount of search hits. The first version of OpenRocket was released in May 2009, RockSim in 1997.
