Open Source Swift Terminals for Windows

Ghostty is a modern terminal emulator designed to deliver high performance, low latency, and a refined user experience for developers. It is built with a focus on speed and efficiency, leveraging modern rendering techniques to provide smooth text display and responsive interaction. The project emphasizes simplicity while maintaining advanced capabilities expected from professional terminal tools. It integrates with modern development workflows and supports customization for user preferences. Ghostty aims to balance minimalism with power, avoiding unnecessary complexity while retaining flexibility. It is particularly suited for developers who want a fast and clean terminal environment. Overall, it represents a next-generation approach to terminal design.

Ghostty Blackhole is a Ghostty terminal shader that renders a ray-traced black hole directly inside the terminal window. It turns terminal contents into the background sky, so nearby text bends, stretches, magnifies, and disappears through the simulated gravitational lens. The shader can run in different size modes, including a Pomodoro-style timing mode, a Claude Code token mode, and a demo mode. In token mode, the black hole grows as Claude Code’s context window fills, creating a visual warning before compaction becomes necessary. The project uses a single fragment shader and live physics-inspired rendering rather than static overlays. It is useful for terminal customization, visual experimentation, and playful feedback during long AI coding sessions.

XcodeGen is a command line tool written in Swift that generates your Xcode project using your folder structure and a project spec. The project spec is a YAML or JSON file that defines your targets, configurations, schemes, custom build settings and many other options. All your source directories are automatically parsed and referenced appropriately while preserving your folder structure. Sensible defaults are used in many places, so you only need to customize what is needed. Very complex projects can also be defined using more advanced features. Generate projects on demand and remove your .xcodeproj from git, which means no more merge conflicts! Automatically generate Schemes for different environments like test and production. Share build settings across multiple targets with build setting groups. Easily copy and paste files and directories without having to edit anything in Xcode.

RepoBar is a macOS menu bar application that provides a real-time dashboard for monitoring GitHub repositories without opening a browser. Built with SwiftUI and AppKit, the tool surfaces key repository signals such as CI status, pull requests, issues, releases, traffic metrics, and recent activity directly in the system menu bar. RepoBar is designed for developers managing multiple repositories simultaneously, offering glanceable insights that reduce context switching and improve workflow awareness. The application also tracks local Git repository state, helping users correlate remote repository activity with their local development environment. It includes a bundled CLI and supports configurable refresh schedules, repository pinning, and fast navigation to GitHub actions or checks. The project emphasizes speed, minimalism, and continuous visibility into development operations.
