A client in your browser, created by Dabdavis (source on GitHub, MIT licence). This is Sandstorm's version, kept closer to the original game. It plays from your own Frontiers disc image, which stays on your computer: it is read here, never uploaded. You sign in on the game's own Station screen.
Recommended browser: a Chromium-based one (Chrome, Edge, Brave, Opera, Chromium) with WebGPU.
Report a problem (F3, also in the game) goes to Dabdavis, who makes the client. Use it only for problems with the client itself: graphics, sound, controls, crashes. Anything about the game on Sandstorm (quests, NPCs, items, your account) goes to our Discord instead.
