Sim racing software

4 tools that sit alongside the sims themselves, with the licence terms, requirements and supported-sim list each project publishes. Other people build and maintain these projects. For the calculators built on this site see tools.

Sims no tracked tool names

Forza Motorsport, Gran Turismo 7, iRacing. None of the 4 projects above names these in the supported list we checked. That is a gap in what these projects publish, not evidence that nothing works.
