SpaceEngine vs Celestia vs Everdust

SpaceEngine runs on Windows ($29.99 on Steam) and supports PC VR headsets; its FAQ says there's no point making a mobile version, and its Steam page lists no Mac build. Nothing on a Mac, a phone or Apple Vision Pro reproduces its 1:1 universe. The closest for roaming a 3D universe is Celestia, free on iPhone, iPad, Mac and Android. Everdust does something else: live simulations you can put your hands in, and a Night Sky whose nebulae and galaxies you fly inside.

  • Pick SpaceEngine if you have a Windows PC with a decent graphics card: it is the deepest universe explorer there is, in VR too.
  • Pick Celestia on a Mac, iPhone, iPad or Android to travel to any planet, star or galaxy in its catalogs, for free.
  • Pick Everdust for physics you can touch, free on Apple Vision Pro, Apple TV, Android phones and tablets, iPhone, iPad and Meta Quest 3 and 3S.

  • Runs on Mac, iPhone, iPad and Android.
  • Free, with an expandable catalog and add-ons.
  • Accurate positions for real solar-system objects.

Where Everdust fits

I make Everdust, so weigh that. Everdust is not a universe explorer: you can't type in a star's catalog number and go there. What you get is simulation: galaxies, black holes and nebulae made of live particles that move with your music and answer your touch, on Apple Vision Pro with your hands.

Everdust's Night Sky on Apple Vision Pro puts the real sky for your place and time around you: look at a planet and pinch to fly there, or at one of its 29 wonders, a nebula, a galaxy or a star cluster, and fly inside it. The Everdust Atlas has a page for each.

The free version covers every world and toy, The Story of Everything in full, and each game's first 3 levels or more and its daily level; Everdust Plus unlocks the rest.

Questions people ask

Is SpaceEngine on Mac? Its Steam page lists Windows only, with no macOS build. On a Mac, Celestia (free) is the closest way to roam a 3D universe.

Is there a mobile version of SpaceEngine? No. Its FAQ says there would be no point, because very few mobile devices are powerful enough. Celestia is on iPhone, iPad and Android, and Everdust runs galaxy and black hole simulations on iPhone, iPad, Android, Apple Vision Pro and Meta Quest.

Does SpaceEngine work in VR? Yes, with SteamVR or Oculus PC headsets, on a Windows PC. It has no Apple Vision Pro or standalone Quest app.

Is there something like SpaceEngine for Apple Vision Pro? Nothing with its scale. Everdust's Night Sky lets you look at a real nebula or galaxy and fly inside it, and Celestia's iPad app runs on Vision Pro in a window.

Is SpaceEngine free? No. It costs $29.99 on Steam, and SpaceEngine PRO, for commercial use, is $69.99. Celestia and Everdust are free.

Checked November 1, 2026. Prices and features change; the store listing is always the final word. I make Everdust, and I’ve tried to describe the other apps as fairly as their makers do. Everdust is also listed on AlternativeTo as an alternative to SpaceEngine and Celestia.
