Stardust is a free interactive cosmic playground built by NebulaTool. Using nothing but your browser, you can sculpt galaxies with your cursor, trigger supernovas with a click, spawn black holes that devour nearby particles, and type words that dissolve into star constellations. The entire experience runs client-side with no downloads, no accounts, and no data collection.
Choose from five distinct particle modes, each with unique physics: Nebula creates flowing connected star fields, Vortex pulls particles into spiraling formations, Firefly produces drifting organic motion, Aurora generates sweeping curtains of light, and Comet sends particles streaming with gravity trails. Six color palettes let you shift the entire cosmic atmosphere from ethereal pastels to toxic neons.
Click anywhere on the intro screen to trigger the Big Bang and begin your cosmic journey. Move your mouse to create particles that trail behind your cursor. Left-click anywhere to trigger a supernova burst that sends over 100 particles exploding outward. Hold the left mouse button to create a gravity well that attracts nearby particles toward your cursor.
Right-click to spawn a black hole with realistic accretion rings and an event horizon that consumes particles. Type any word on your keyboard and watch it appear as ghost text before dissolving into hundreds of star particles that form the shape of your letters.
