Starfield
ParticlesDescription
Cinematic night sky with three parallax star depths, color-temperature-varied stars, a subtle fbm milky-way band with a dust rift, gentle twinkle, anamorphic hero-star flares, and occasional shooting stars with properly fading tails.
What is the starfield background?
Starfield is a free starfield background that renders in real time with WebGL, so it stays sharp on any screen without shipping a heavy video file or GIF — and it pauses while off-screen to keep pages fast.
Use it as visual inspiration for a hero or section background on a landing page, portfolio, SaaS site or app. Every parameter — colors, speed and intensity — is adjustable in the remix playground. No account is needed to preview it.
Make it yours
Every knob below is tuned by the AI to match your design — or ask for changes in plain language, like “slower and more blue.”
colorsPaletteStar temperature palette ordered cool to warm; picks are skewed toward the first (cool) entries with rare warm accents, and the first two colors also tint the milky-way haze.
bgPaletteDeep sky base color; gets a zenith-to-horizon gradient and faint same-hue horizon lift.
bg-alpha0–1Background opacity; at 0 the stars composite as pure additive light over the host section (un-premultiplied, no dark halos).
speed0.02–2Parallax drift rate; near stars move ~5x faster than far ones. Keep low (0.15-0.4) for the expensive film-title feel.
density0.1–1Star population across all layers; the far layer is automatically denser inside the milky-way band.
size0.1–1Star core and halo scale; higher values give dreamier bokeh-like bright stars.
depth1–3Number of parallax sheets: 1 = mid field only, 2 adds dense far stardust, 3 adds sparse near hero stars with anamorphic flares.
twinkle0–1Scintillation amount; double-sine shimmer per star, automatically steadier on bright stars for realism.
shooting0–1Shooting star frequency (0 = off); two staggered emitters with random skips, tapering tails that grow then burn out.
angle0–360Sky orientation in degrees: sets the milky-way band diagonal, the parallax drift direction along it, and the meteor travel direction.
mouse0–1Depth-parallax strength. As the cursor drifts from center, the star sheets counter-shift by depth — near hero stars travel most (a few percent of the frame), the far stardust barely, and the nebula haze least of all — selling a gentle window-into-space camera lean. The offset saturates softly toward the edges, holds while the pointer rests, and 0 disables it entirely for the pure ambient render.
Frequently asked questions
Yes. You can preview the starfield background for free in the AIDesigner effects library — no watermark and no sign-up required to try it.
Use "Remix this effect" to tune the colors, speed, and parameters, then use the preview as a reference for your website background implementation.
It renders on the GPU through WebGL at a capped frame rate, so it is far lighter than a background video and automatically stops drawing when it scrolls out of view — keeping load and battery impact low.
Yes. Every knob in the "Make it yours" section is adjustable, and you can also just ask the AI in plain language — for example "slower and more blue" — and it retunes the starfield background to match.

Rounded glass flutes acting as true cylindrical lenses over a fluid two-tone light field: every rib compresses and mirrors the scene across its whole width while the rims light-pipe and disperse it — every visible line is displaced light, nothing painted on.

Animated flow field quantized through a Bayer matrix into a limited ink palette — crisp retro risograph halftone dithering with chunky pixels, wind-swept ribbons, and a drifting luminous core.
Noise Shimmer
Premium film-texture finish: slow thin-film iridescent ribbons with fine animated grain and a subtle vignette.
