Official vendor sites – best for updates, signatures, and support
AlternativeTo – best for finding legal replacements
MajorGeeks – curated Windows download library
Softpedia – broad catalog of freeware, demos, and official builds
Steam / GOG / Epic – safer legal game storefronts
When possible, always prefer the original publisher. If your goal is discovery rather than piracy, reputable software directories are much safer than cracked download sites.
