This page lists various fan-made tools that can help calculations related to the gameplay of Kerbal Space Program. Unlike addons, they do not directly influence the game, as they are run separately.
The table cells that are shaded blue are links to the KSP Forums, to indicate open source tools and compatibility with the latest version of KSP. Conversely, tools who's last known compatible version is too far into the past are shaded red as are non-free tools and websites gone missing.
The KSP forums have a section dedicated to such tools here, which is where it is most likely that new tools and versions will be announced.
