# CanYouMod > CanYouMod (canyoumod.com) is a free, unofficial field guide to universal-modder, the MIT-licensed open-source game-modding plugin for Claude Code and other coding agents by rehan-remade (https://github.com/rehan-remade/universal-modder). Pick a PC game and get a verdict (moddable offline / experimental / not recommended), the engine, a recommended route, prerequisites and a copyable starter prompt. No account, no uploads, offline single-player only — no anti-cheat or DRM bypasses. Key facts: - universal-modder is not made by CanYouMod and not by Anthropic. CanYouMod is an independent guide; it does not run the plugin. - Install in Claude Code: `/plugin marketplace add rehan-remade/universal-modder` then `/plugin install universal-modder@universal-modder`. - 36 games assessed: 17 moddable offline, 8 experimental, 11 not recommended (anti-cheat / live-service games). - Assessments are documentation-based (last reviewed 2026-10-04), not hands-on certification. Always back up saves. ## Core pages - [Game checker](https://canyoumod.com/): pick a game, get a verdict and a starter prompt - [Game directory](https://canyoumod.com/games): all 36 assessed PC games - [Install guide](https://canyoumod.com/install): 7 ways to install universal-modder (Claude Code, Codex, Gemini CLI, VS Code + Copilot, Cursor, Skills only, Git clone) - [Engine guides](https://canyoumod.com/engines): .NET / XNA / FNA, Unity, Creation Engine / Gamebryo - [About & methodology](https://canyoumod.com/about): what each verdict means, sources and review process - [Privacy policy](https://canyoumod.com/privacy): no accounts or trackers; purchases processed by Waffo Pancake - [Contact & support](https://canyoumod.com/contact): email support@canyoumod.com or the online support form - [Full text for LLMs](https://canyoumod.com/llms-full.txt): every verdict, prerequisite and starter prompt in one Markdown file - [Machine-readable data](https://canyoumod.com/data/games.json): JSON of all assessments ## Moddable offline - [Can you mod Terraria?](https://canyoumod.com/games/terraria): Moddable offline — .NET / XNA / FNA.
