Project ideas from Hacker News discussions.

Tether: iMessage, SMS, etc. on Linux

📝 Discussion Summary (Click to expand)

Theme 1 – Licensing and openness
Many commenters debated whether putting an interoperability protocol behind a copyleft license is problematic and celebrated the switch to a permissive MIT license.
- “Personally, I think putting an interoperability protocol implementation behind a copyleft license is a little unfortunate!”pzmarzly
- “Isn't this[0] the use-case that is supposedly covered by LGPL?”kees99
- “Huh, haven't thought of it. Just relicensed ancs4linux to MIT.”voakbasda

Theme 2 – Hope vs. cynicism about small contributions
The thread swung between seeing the license change as a hopeful sign of community cooperation and dismissing it as trivial in the face of larger societal problems.
- “I love HN. Read an article that raises a reasonable point about a project’s license, and that project’s author shows up to announce they were convinced and changed the license accordingly… It’s things like this that give me hope for the world.”voakbasda
- “Not to be Debbie Downer but software licensing has no effect on what matters to billions of people… If a dude changing an inconsequential text file on GitHub gives you hope for the world, then please broaden your perspective.”stackghost
- “It’s things like this that rob my of my hope for the world.”stackghost (later)

Theme 3 – Apple‑Linux interoperability and tooling gaps
Users expressed frustration with Apple’s walled garden, praised efforts that bridge the gap (e.g., Tether), and critiqued existing solutions like KDE Connect for iOS.
- “Mega‑kudos to the author for chipping away at the wall around Apple’s garden. Apple’s refusal to provide interoperability borders on criminal.”voakbasda
- “I find KDE Connect severely lacking… Even features that do exist don't always work reliably. I can't send files between devices, most of the time clipboard sharing doesn't work either…”cassianoleal
- “Before you ask, I know KDE Connect exists. It's great! If you're on Android you should definitely use it. The problem is that it didn't do what I wanted and it's roadmap indicated it never would.”(quoted from the article by cassianoleal)


🚀 Project Ideas

TetherPro: Reliable iMessage & SMS Bridge for Linux

Summary

  • Provides end‑to‑end encrypted iMessage and SMS synchronization between iPhone and Linux desktop over Bluetooth and local Wi‑Fi.
  • Features auto‑reconnect, comprehensive diagnostics, and a polished GTK/Qt UI to eliminate the pairing and reliability issues seen in existing tools.

Details

Key Value
Target Audience Linux desktop users who own an iPhone and need seamless messaging continuity
Core Feature Bidirectional iMessage/SMS sync via Bluetooth MAP/ANCS secured with mTLS, plus clipboard and file transfer
Tech Stack Rust (core service & Bluetooth stack), GTK 4 (UI), libimobiledevice, BlueZ, OpenSSL, optional WASM‑based plugin system
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters highlighted Tether’s flaky pairing, unclear docs, and lack of auto‑reconnect; TetherPro directly addresses those pain points.
  • By delivering a stable, open‑source bridge, Linux users can stay within the iMessage ecosystem without needing a Mac.

KDE Connect Plugin Hub

Summary

  • A centralized marketplace and SDK for community‑created plugins that extend KDE Connect/GSConnect with new features (e.g., iMessage support, custom actions, encrypted file sharing).
  • Simplifies discovery, installation, and updates of plugins while maintaining a stable core.

Details

Key Value
Target Audience KDE and GNOME Linux users who want to extend their device‑to‑device connectivity
Core Feature Plugin SDK (Qt/QML/C++) and a web‑based hub for browsing, rating, and installing plugins
Tech Stack Qt/QML, C++ (core), Node.js/Express (hub API), PostgreSQL, Docker, GitHub Actions for CI
Difficulty Medium
Monetization Hobby

Notes

  • Users repeatedly asked for a proper plugin system to avoid waiting on the KDE Connect roadmap; this hub enables rapid community‑driven innovation.
  • It lowers the barrier for contributors (like those wanting iMessage support) to ship features without fork‑maintaining the whole project.

BluStable: Auto‑Reconnect Bluetooth Manager for Linux‑iOS

Summary

  • A daemon and GUI that monitors Bluetooth link health, automatically attempts re‑pairing, and seamlessly falls back to Wi‑Fi Direct (via libimobiledevice) when the Bluetooth link degrades.
  • Includes connection diagnostics, logging, and notifications to keep users informed.

Details

Key Value
Target Audience Linux users experiencing unstable Bluetooth connections with iOS devices (KDE Connect, Tether, etc.)
Core Feature Watchdog service that detects drops, triggers re‑pairing, and switches to Wi‑Fi Direct without manual intervention
Tech Stack Rust (daemon & DBus integration), BlueZ, libimobiledevice, GTK 4 (system tray UI), systemd service
Difficulty Medium
Monetization Hobby

Notes

  • Commenters complained about needing to restart apps, sporadic connections, and unclear error states; BluStable provides a proactive solution.
  • By stabilizing the link, existing tools become more reliable, reducing frustration for daily users.

OpenContinuity: Open Implementation of Apple Continuity Features

Summary

  • Implements an open, secure, local‑network‑based Continuity stack (clipboard sync, Handoff, Universal Clipboard) that works between Linux desktops, Android devices, and a companion iOS app.
  • Uses mTLS and multicast DNS for discovery, avoiding dependence on Apple’s proprietary services.

Details

Key Value
Target Audience Power users who want seamless copy‑paste and app handoff across Linux, Android, and iPhone without a Mac
Core Feature Local‑only service that syncs clipboard contents and app state in real time using encrypted UDP/TCP channels
Tech Stack Go (core service & mTLS), Flutter (companion iOS/Android app), GTK 4 (Linux UI), Avahi for MDNS, gRPC for payload exchange
Difficulty High
- Monetization Hobby

Notes

  • Users praised the idea of true continuity (copy/paste, Handoff) but noted the lack of open alternatives; OpenContinuity fills that gap.
  • Provides a privacy‑respecting way to achieve Apple‑like interoperability while staying fully open source.
