Lume – OS lightweight CLI for MacOS and Linux VMs on Apple Silicon▲309
We just open-sourced Lume - a tool we built after hitting walls with existing virtualization options on Apple Silicon. No GUI, no complex stacks - just a single binary that lets you spin up macOS or Linux VMs via CLI or API. Why we built Lume: - Run native macOS VMs in 1 command, using Apple Virtualization.Framework: `lume run macos-sequoia-vanilla:latest` - Prebuilt images on https://ghcr.io/trycua (macOS, Ubuntu on ARM) - API server to manage VMs programmatically `POST /lume/vms` - A python SDK on github.com/trycua/pylume Run prebuilt macOS images in just…

Oliphaunt – A native Mastodon client for macOS▲105
I’ve been building Oliphaunt, a native Mastodon client for macOS, as a solo project — designed to be fast, lightweight and feel right at home on the Mac. It’s not built with Catalyst or Electron framework. Key features: • Native macOS UI using AppKit with some SwiftUI integration (not a web wrapper) • Core Data for local caching • Responsive, keyboard-friendly interface • UX tailored for desktop-class Mac computers • Supports multiple accounts, cross-instance timelines and search You can try it via TestFlight (macOS 14+ Sonoma): https://testflight.apple.com/join/Epq1P3Cw…

Mocktail – Free, open-source mock API server with a built-in dashboard▲25

You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding…
