Developer Builds Windows Port of Ghostty Terminal in 3 Days Using AI Agents

A developer forked Ghostty, the terminal emulator created by Mitchell Hashimoto, and released a functional Windows version in just three days, starting September 1st. The project was completed without the developer writing a single line of code, with all 246 commits handled by Claude AI. The work was managed through a custom AI coordination system, where one AI acted as a manager overseeing three to four Claude worker sessions that divided and executed tasks collaboratively. The developer chose Rust for the Windows-specific layer — totalling 45 files and 48,000 lines — primarily because Rust offers strong Microsoft-backed support for COM, the Windows input system that Zig cannot handle reliably. The project also served as a real-world test of the developer's own AI CLI manager tool, which was itself built using the same multi-agent workflow.
