QNX is now free for anything non-commercial, plus there's an RPi image

Original Article ↗ Hacker News Discussion ↗

BlackBerry’s QNX real-time operating system is now available free of charge for non‑commercial use, with a Raspberry Pi 4 image and full development tools, aiming to attract hobbyists, students and smaller teams into its ecosystem. Commenters praise QNX’s microkernel design, real‑time capabilities and use in safety‑critical systems, but many are wary after previous “rug pulls,” restrictive licensing terms and stronger competition from real‑time Linux and open‑source RTOSes. A recurring theme is that meaningful traction would likely require truly open-sourcing QNX or adopting a more developer‑friendly commercial model.

Overview of the Release

  • QNX 8.0 is now free for non‑commercial use, with an RPi 4 image and other BSPs.
  • Non‑commercial license is described as perpetual and self‑service, giving access to the full development suite and targets.
  • Intended audiences called out: students, hobbyists, academics, and small non‑profit projects.

Licensing Model and Trust Issues

  • Many commenters welcome a free tier but criticize:
    • Prior “rug pulls” (source available twice before, then abruptly closed).
    • A termination clause letting BlackBerry revoke licenses at any time.
    • “High‑risk application” and “societal loss” wording seen as vague and risky.
    • Requirement to sign on behalf of institutions and hardware telemetry collection.
  • Some argue only true open source (e.g., GPL/AGPL or permissive licenses) would rebuild trust; others propose an Unreal‑Engine‑style royalty model.
  • Several say they will not invest time in QNX again without a fully open license.

Technical Characteristics and Comparisons

  • QNX described as a microkernel RTOS with:
    • Message‑passing IPC tightly integrated with scheduling, priority inheritance, and network transparency.
    • User‑space drivers that can be restarted, and minimal kernel (no paging by default).
    • Strong POSIX compatibility, making many Unix CLI tools portable.
  • Praised for deterministic latency and suitability for safety‑critical and high‑availability systems (automotive, industrial, medical).
  • Comparisons:
    • Versus Linux: PREEMPT_RT now in mainline; some say that makes QNX less relevant, others argue Linux still isn’t a true hard‑real‑time OS or easily certifiable.
    • Versus FreeRTOS/Zephyr/etc.: QNX occupies a different niche (full OS with MMU, drivers, GUIs, not just a tiny executive).
    • Some suggest seL4 or other microkernels for security/verification; others note those are more minimal than QNX.

Use Cases, Relevance, and Alternatives

  • Existing deployments mentioned in cars (infotainment, instrument clusters, ADAS) and telecom/routers.
  • Some see QNX as “20 years too late” for new adoption, squeezed by Linux from above and lightweight RTOSes from below.
  • Others argue diversity beyond Linux monoculture is valuable, especially for certified safety systems.
  • Hobbyist project ideas discussed: robotics, Trilobot, weather stations, cash registers, classic games.

Developer Experience, Ecosystem, and Accessibility

  • Some praise the core developer experience (POSIX tools, CMake, microkernel design).
  • Major complaints:
    • Poor or lagging driver/BSP support vs Linux.
    • Small, aging community; few examples; “working with 25‑year‑old software”.
    • Heavy friction to try it: mandatory account, license flows, license manager, QNX Software Center just to download images.
    • Password/account system seen as outdated and restrictive.
  • Suggestions: easier downloads without accounts, VM images like Microsoft’s, bug portal, better docs, and clear positioning on “what QNX is” on the marketing site.

Desktop, UI, and Nostalgia

  • Strong nostalgia for:
    • The 1.44MB demo floppy with GUI+browser.
    • Photon microGUI and earlier desktop‑capable QNX releases.
    • Historical speed and “snappy” feel compared to contemporary OSes.
  • Photon is confirmed long‑dropped; modern QNX targets embedded/graphical systems, not general desktops, though community window managers exist.
  • Some recall earlier QNX on PDAs, the ICON school computers, and BB10/PlayBook devices, lamenting missed opportunities.
