Will Hollow Knight: Silksong support mods?

Short answer: Yes — on PC Silksong already supports fan-made mods via community mod loaders and managers rather than an official in-game mod toolkit. The PC scene moved fast after launch: popular mod frameworks and installers (for example BepInEx-based toolchains) and dozens of mods are available on the Nexus Mods Silksong hub. Team Cherry hasn’t shipped a dedicated public “mod API” at launch, but they’ve been tolerant of the community and even incorporated a fan-made Chinese translation into Patch 4 as an official option. See reporting on that decision for context (PC Gamer report on Patch 4).

For practical modding you’ll typically use third‑party tools and managers and can find examples such as community mod managers and plugins, quality‑of‑life packs, and gameplay swaps (e.g., mods that add the Knight or QoL features). Popular resources and coverage include the Nexus Mods Silksong mod manager page and media writeups showing how the community has already released big mods like the Knight-in-Silksong conversion (GamesRadar coverage). If you plan to mod, stick to PC, back up saves, and follow mod authors’ install notes since official patches can occasionally break community tools.
