Let’s be upfront: Bob’s Track Builder is technically abandonware . The original developer (BobsTrackBuilder.com) has been offline for years. The official paid license system no longer works.

: The free/demo version of BTB does not export to rFactor or GTR2. You can only save and view tracks. For full exports, you need a Pro license, which is no longer sold. So a "free download" is mostly useful for learning or building tracks for personal viewing, not for racing AI.

The safest way to acquire a free version is by downloading the official demo directly from the creator.

Join sim racing modding Discords like "rFactor Tracks & Cars" or "Assetto Corsa Modding Central". In their #resources or #legacy-tools channels, you will frequently find pinned links to BTB.

Go to the "Modding" or "Tracks" subforums. Search for "BTB download". Veteran modders often maintain sticky threads with legacy tools. You may need to register a free account to see download links.

If you decide to proceed, here are the most reliable sources (as of this writing). Avoid random "crack" websites that promise a download—they are full of malware.
