Oliphaunt – A native Mastodon client for macOS

In plain words

Oliphaunt is a native Mastodon client for macOS built with AppKit and SwiftUI, designed to be fast and lightweight without using Electron or Catalyst. It features a keyboard-friendly interface optimized for desktop use, local caching through Core Data, and support for multiple accounts and cross-instance timelines. The application is available as a TestFlight beta for macOS 14 and later.

In the maker’s words, at launch

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…

  A native macOS client for Hacker News, built with SwiftUIFeb 2026 · github.com · ▲265

  Hey HN! I built a native macOS desktop client for Hacker News and I'm open-sourcing it under the MIT license.

  Ghost Pepper – Local hold-to-talk speech-to-text for macOSApr 2026 · github.com · ▲467

  I built this because I wanted to see how far I could get with a voice-to-text app that used 100% local models so no data left my computer. I've been using a ton for coding and emails. Experimenting with using it as a voice interface for my other agents too. 100% open-source MIT license, would love feedback, PRs, and ideas on where to take it.

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
