Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Huly

  • Cloud pricing charges separately for storage and video/audio bandwidth, which can be unpredictable.
  • AI features are listed as 'TBD' rather than fully available.
  • Being a broad all-in-one tool, individual modules are less deep than dedicated best-of-breed products.
  • Self-hosting requires operational effort compared to fully managed competitors.

Stellarium

  • It is desktop-only software, so it has no native touch-optimised phone interface; the similarly named mobile app is a different paid product from a different company.
  • As a volunteer-maintained open source project, support is community-based rather than a guaranteed commercial help desk.
  • The interface, while capable, is less immediately intuitive for a first-time user than a polished commercial phone app.
  • Telescope control and some advanced plugins require additional setup that a non-technical user may find fiddly.
  • Because it shares a name with the unrelated paid Stellarium Mobile Plus app, buyers researching pricing online can easily conflate the two products.
