Show HN: I completed shipping my desktop app

Original Article ↗ Hacker News Discussion ↗

An indie developer has launched Pimosa, a cross‑platform desktop app that wraps tools like FFmpeg and ImageMagick to make common video, image, and audio tasks easier for non‑technical users. Commenters praise the polished UI and focus on offline, one‑time‑purchase licensing, while offering detailed feedback on the landing page, demo media, pricing presentation, and platform support (especially Windows installers and a potential Linux build). A recurring theme is how to fairly credit and comply with open‑source dependencies, alongside debate over whether a paid GUI “wrapper” around powerful free tools provides enough distinctive value and how sustainable lifetime updates are as a business model.

Overall reception

  • Many commenters praise the app, UI polish, and the fact it’s a native-feeling desktop app instead of a cloud/SaaS tool.
  • Several find it inspiring as a solo-dev project and appreciate the fast-loading website.
  • A subset dismiss it as “just another paid FFmpeg wrapper,” but others argue that a good desktop UX on top of CLI tools is real value.

Tech stack & architecture

  • App built with Flutter, using SQLite; Next.js is used for the marketing site.
  • It relies on FFmpeg and ImageMagick, which are not bundled: on macOS they are installed via Homebrew scripts.
  • This design is explicitly chosen to stay on the right side of FFmpeg’s LGPL/GPL licensing.

UX, website, and onboarding

  • Landing page is visually appealing but criticized for:
    • “Buy now” being very prominent before screenshots or clear value explanation.
    • Pricing layout looking like a subscription even though it’s one-time.
    • Weak SEO (repeated titles), some grammar issues, unclear download/trial behavior.
  • Demo GIFs/videos are seen as too slow, unclear, or broken on some mobile browsers.
  • Navigation quirks: tools dropdown doesn’t close or scroll well; some elements look clickable but aren’t.

Pricing & licensing debate

  • App is sold as a one-time purchase with lifetime updates.
  • Multiple commenters strongly advise against lifetime updates; recommend:
    • Per-major-version licenses or one year of updates plus paid upgrades later.
  • Heated side-thread on subscriptions vs perpetual licenses, “ownership,” and expectations for long-term maintenance.

Security, distribution & installers

  • macOS users are wary of entering their device password; dev points to public install scripts.
  • Windows users strongly request a standalone EXE/MSI installer instead of relying only on the Microsoft Store, citing enterprise restrictions, offline use, and “lifetime license” concerns.
  • Long subthread on the pain of Windows code signing, EV vs regular certs, and SmartScreen/Defender behavior.

FFmpeg/ImageMagick credit & ethics

  • Several argue the site should clearly credit FFmpeg and ImageMagick (beyond a hidden credits page), both for license compliance and ethics.
  • There’s a broader philosophical debate:
    • One side: charging for a GUI over massive FOSS codebases without visibly acknowledging them feels wrong.
    • Other side: licenses permit it; UI/UX, packaging, and distribution are substantial work and deserve compensation.

Feature requests & bugs

  • Requests include: Linux version (Flatpak/AppImage), better batch workflows, text overlays/GIF workflows, subtitle tooling, screen recording integration, HEIC/JPEG XL support, lossless editing, GoPro/batch trimming tools.
  • Various minor bugs reported in UI, cropping handles, filename collisions, typos, roadmap staleness; dev indicates some are already fixed or being patched.
