Starfield

Particles
Interactive — move your cursor

Description

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.”

colorsPalette

Star 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.

bgPalette

Deep sky base color; gets a zenith-to-horizon gradient and faint same-hue horizon lift.

bg-alpha0–1

Background opacity; at 0 the stars composite as pure additive light over the host section (un-premultiplied, no dark halos).

speed0.02–2

Parallax drift rate; near stars move ~5x faster than far ones. Keep low (0.15-0.4) for the expensive film-title feel.

density0.1–1

Star population across all layers; the far layer is automatically denser inside the milky-way band.

size0.1–1

Star core and halo scale; higher values give dreamier bokeh-like bright stars.

depth1–3

Number of parallax sheets: 1 = mid field only, 2 adds dense far stardust, 3 adds sparse near hero stars with anamorphic flares.

twinkle0–1

Scintillation amount; double-sine shimmer per star, automatically steadier on bright stars for realism.

shooting0–1

Shooting star frequency (0 = off); two staggered emitters with random skips, tapering tails that grow then burn out.

angle0–360

Sky orientation in degrees: sets the milky-way band diagonal, the parallax drift direction along it, and the meteor travel direction.

mouse0–1

Depth-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.
