ModSmith Pro
A downloadable tool
ModSmith Pro is a game mod support planner for game developers who want to ship mod-friendly games without drowning in support tickets.
Plan mod support for your game before you write a line of mod code:
- Design a versioned mod API contract — define hooks, events, and data endpoints, then version them so every mod declares exactly what it needs.
- Resolve real mod dependencies — run a topo-sort resolver that orders your mod set, handles optional dependencies and semver ranges, and fails loudly on dependency cycles instead of silently breaking load order.
- Simulate an API 1.x → 2.0 break — see what a breaking API change does to your mod set before you ship it.
- Follow a researched Steam Workshop integration checklist — publishing, updating, and moderation steps distilled from real integrations.
- Plan mod safety tiers — sandbox levels, permission scopes, and review flows matched to how much trust each mod deserves.
Offline, runs locally in the browser — your designs never leave your machine.
This is the full Pro version: unlimited hooks and mods, exports, and adversarial presets. One-time purchase, yours forever.
Try before you buy: the free ModSmith demo (https://theluckyduck666.itch.io/modsmith) includes the core planner with limits (10 hooks, 12 mods, no export).
