FWIW Lazarus[1] has its own CHM generator and CHM viewer which uses its own HTML engine written on top of its LCL framework, making it cross platform. Though personally i prefer the native viewer on Windows as LHelp (Lazarus' viewer) feels a bit clunky. (the generator actually comes from Free Pascal, but the viewer is only on Lazarus) [1] https://www.lazarus-ide.org/ https://www.lazarus-ide.org/
