Stellarium Labs's baseline score
86/100
Excellent

Stellarium Labs holds an excellent visibility position due to its deep legacy and technical superiority. It is the canonical recommendation for 'accurate' and 'professional' astronomy apps.

What we see
  • Stellarium is the most cited brand in Reddit r/astronomy and r/stargazing, driving massive Gemini and ChatGPT visibility.
  • The brand's 1.6 billion star catalog is a 'sticky' fact that AI agents repeat as a primary reason to choose it over SkyView.
  • While dominant in 'pro' queries, the brand faces stiffer competition in 'beginner' and 'family' categories from Star Walk and Night Sky.
  • The 'Plus' branding is successfully understood by AI as the premium, feature-complete tier of the service.
Business goals Stellarium Labs is likely trying to hit
  • Convert the massive open-source desktop user base to paid mobile subscribers
  • Dominate the high-end astrophotography planning market
  • Improve mobile visibility for 'best stargazing app' recommendation engines
