Open Source TypeScript Game Mods

r2modman is an open-source, cross-platform mod manager designed to simplify installing, organizing, and maintaining game modifications for a wide range of PC titles that use the Thunderstore ecosystem. Built with Electron, TypeScript, and Vue, the application focuses on providing a clean, beginner-friendly interface so players can manage complex mod setups without deep technical knowledge. It allows users to download, enable, disable, update, and uninstall mods with a few clicks while keeping the base game playable through normal launchers like Steam. The tool supports multiple popular mod-heavy games such as Risk of Rain 2, Valheim, GTFO, and others, making it a central hub for Thunderstore-based modding workflows. One of its core strengths is the profile system, which lets users maintain separate mod configurations for different play styles or multiplayer compatibility.

x-minecraft-launcher is an open-source Minecraft launcher designed to provide a modern user interface and powerful tools for managing modded Minecraft environments. The application allows players to install and manage multiple instances of Minecraft, each with its own configuration, mods, resource packs, and runtime settings. It emphasizes efficient disk usage by sharing resources between instances rather than duplicating files, which helps reduce storage consumption when working with many modpacks. The launcher integrates directly with major mod distribution ecosystems and supports downloading mods, modpacks, and dependencies from various repositories. Built with modern web and desktop technologies, it focuses on performance, modular architecture, and cross-platform compatibility across Windows, Linux, and macOS systems. The project also supports different authentication systems and allows advanced configuration of Java runtime parameters and game settings.

Decky Loader is a homebrew plugin launcher built for the Steam Deck that enables users to extend and customize the console’s functionality through a dynamic plugin ecosystem integrated directly into the SteamOS interface. It acts as a middleware layer that injects and manages plugins, allowing deep customization such as modifying UI elements, changing system sounds, adjusting display properties, and extending system behavior beyond stock capabilities. The platform is designed to persist across system updates and reboots, ensuring continuity of installed plugins without manual reconfiguration. It supports advanced developer features such as two-way communication between plugins and the loader, as well as interoperability between Python backends and TypeScript React frontends. Decky Loader also allows plugins to bypass typical browser restrictions like CORS, enabling more powerful integrations with external data sources.

roblox-ts is an attempt to bridge the abilities of TypeScript to work in a Roblox environment. We break down your code into an abstract syntax tree and emit functionally similar structures in Luau so that the code behaves the same.

Microsoft MakeCode, short for Programming eXperience Toolkit, is an open-source framework developed by Microsoft for creating beginner-friendly programming environments and educational coding tools. The toolkit serves as the foundation for Microsoft MakeCode, a platform used to teach programming through interactive editors that support both block-based and text-based coding. PXT enables developers to build custom programming environments that can run in web browsers or local development setups, making it suitable for educational hardware platforms such as microcontrollers and classroom devices. The system uses a subset of TypeScript as its underlying programming language, simplifying JavaScript syntax while maintaining compatibility with modern development workflows. Through its modular design, developers can create specialized editors and programming experiences tailored to specific devices or learning contexts.

MCSManager Panel (MCSM) is a modern, secure, and distributed control panel designed for managing Minecraft and Steam game servers. MCSManager has already gained a certain level of popularity within the community, specifically Minecraft. MCSManager excels in offering a centralized management solution for multiple server instances and provides a secure and reliable multi-user permission system. In addition, We are committed to supporting server administrators not only for Minecraft but also for Terraria and various Steam games. Our goal is to foster a thriving and supportive community for game server management.

Mirror Engine is an experimental game engine and development platform designed as an alternative environment for building multiplayer virtual worlds similar to platforms such as Roblox or Unreal Editor for Fortnite. The project is built on top of the Godot engine and attempts to combine both the game client and development editor into a single integrated environment. The goal of the platform is to allow developers and creators to collaboratively build interactive worlds in real time without needing to manage backend infrastructure such as networking, asset hosting, or authentication systems. The repository includes components for both the engine application and supporting server infrastructure, allowing the platform to function as a full game development ecosystem. The engine aims to simplify the process of building multiplayer experiences by providing built-in networking, asset management, and synchronization systems.

RenderPilot is an open-source Windows application for managing rendering components used by PC games. It automatically discovers installed games and shows which rendering libraries they use, making it easy to update, downgrade, or restore components without manually working through game folders. It also integrates rendering add-ons such as RenoDX and Luma, provides per-game NVIDIA DLSS controls, and automatically keeps backups for safe rollback. Everything stays local: RenderPilot requires no account and collects no telemetry.

OSRS .json Hiscores is a server-side API wrapper designed to transform Old School RuneScape hiscores data into structured and developer-friendly JSON objects, addressing limitations in the official API’s output formats. The official API typically returns CSV or basic arrays, which can be difficult to work with, so this project restructures the data into meaningful objects that include player stats, rankings, and inferred metadata. It also adds additional logic to determine player game modes, including historical transitions such as de-ironing or hardcore status changes. The library includes functions for retrieving leaderboard pages, skill rankings, and activity statistics, making it suitable for building analytics dashboards or game-related applications. It supports TypeScript with full type definitions, improving developer experience and reliability when integrating into backend systems.
