Rekee allows to design custom racing tracks for the Rallyman: GT and Rallyman: DIRT board games. The editor application is optimized for desktop screen sizes and modern browsers with WebAssembly support.
Use the mouse to drag tiles from the catalog (left side) and drop them on the map (right side). Additionally the editor supports a "quick building" mode: double-click on catalog tiles will auto-append the tile at the map position highlighted by an arrow icon. When pressing the Shift or Ctrl keys (Cmd on Mac) during double-click the tile will be appended either as a left or right curve.
This project is under development with improvements and features to be added, or possibly changed in upcoming versions. Contributions are welcome, you can get involved with the project on GitHub.
