Developer Builds Minecraft Launcher with Claude Code
Project Overview
BlockHaven Launcher is a free, open-source Minecraft launcher built using Claude Code. The developer, who has 20+ years of software development experience, directed the entire development process without writing specifications or code themselves.
Technical Implementation

- TypeScript for type safety
- Microsoft OAuth for authentication
- Modrinth API integration for mod browsing
Key Features
- Microsoft authentication system
- Modrinth mod browsing capabilities
- Isolated multi-instance profiles
- Server auto-connect functionality

Development Workflow
The developer described the desired architecture and tech stack to Claude Code, which then:
- Wrote the design documents
- Implemented the code
- Utilized start-work skills/tooling for development
The developer's role was directing the process rather than writing specifications or code. The repository is fully public, allowing other developers to examine what Claude Code produces for a real desktop application.
