HSGuides is a community resource for players of Hero Siege, combining a build planner and wiki to help users plan, explore, and share character setups. Its tools cover full skill trees, gear loadouts, and an incarnation planner, alongside a loot-filter library and a comprehensive item database. Players can browse community-created guides for every class, with builds spanning different playstyles, progression stages, and seasons.

Featured examples include Plague Doctor vitality builds, Demon Slayer and Pirate setups, summoner and physical Prophet guides, and builds for classes such as Necromancer, Illusionist, Marksman, and Shield Lancer. The site also provides downloadable or shareable loot filters tailored to activities and preferences, from leveling and Nightmare play to strict endgame filtering. Users can access build lists, manage their own builds, and consult the wiki for game-related information.

HSGuides identifies itself as a community tool, says it is not affiliated with Panic Art Studios, and notes that its data comes from Hero Siege Helper and Hero Siege game files
